Drencher fire extinguishing system: in detail from A to Z

Setting up the proper fire extinguishing system is essential to protecting your house from flames. A system that is becoming more and more popular is the drencher fire extinguishing system. We’ll go into great detail about the drencher system in this post, covering everything from its installation and upkeep to its fundamental ideas.

By continuously spraying water or other extinguishing agents over the affected area, the drencher fire extinguishing system is intended to put out fires fast and efficiently. Drencher systems concentrate on flooding a particular zone with a concentrated flow of extinguishing agent, offering quick suppression in targeted areas, as opposed to conventional sprinkler systems that spray water over a large area.

One of the key components of a drencher system is the detection mechanism, which triggers the release of the extinguishing agent upon detecting signs of fire. This can include smoke detectors, heat sensors, or flame detectors strategically placed throughout the property. Once activated, the system springs into action, delivering a powerful stream of water or other suppressants to smother the flames.

To guarantee maximum coverage and efficacy, installation of a drencher fire extinguishing system necessitates meticulous planning and coordination. Before designing and installing the system, professionals usually evaluate the property’s layout and unique fire risks. This could entail figuring out where to put nozzles, pipes, and detectors to optimize coverage and reduce reaction times in the event of a fire.

To guarantee a drencher system’s dependability and efficiency, routine testing and maintenance are necessary. This entails examining detectors, examining pipes for leaks or damage, and confirming that control panels and release mechanisms are operating properly. Frequent testing processes guarantee that any problems are found early on and that the system is still prepared to react efficiently in an emergency.

Component	Description
Activation System	Triggers the drencher system in case of fire detection.
Piping Network	Distributes water throughout the building, usually installed overhead.
Nozzles	Discharge water evenly across the protected area when activated.
Water Supply	Provides the necessary water volume and pressure for the system to operate effectively.
Control Panel	Monitors the system"s status and allows manual activation or deactivation.

Principle of operation of the fire extinguishing system.

The supply of extinguishing composition to the protected room via the action of sensors forms the foundation of the drencher fire extinguishing system’s operation. Regardless of the burning area, the entire drainage protection area is supplied with extinguishing composition. This makes it possible to put out the fire more quickly, stop it from spreading, and, if needed, also ensure that other objects are protected from the fire’s hazardous elements.

The following are the parts that make up the drencher extinguishing system:

Water source with pumps for the supply of extinguishing agent

For the system to run continuously for at least 60 minutes, there should be two power sources. Additionally, a backup pump is installed, which will supply the extinguishing agent through the pipelines in the event that the primary pump malfunctions or fails.

Pipeline system.

Metal pipes with the proper paint job are oriented in relation to the supply of foam and water. The method used to fill the pipelines with extinguishing agent is what makes drainage systems unique. Until the fire detection system is activated, the pipelines are typically left empty. The extinguishing agent is fed into the pipelines for extinguishing after being triggered.

This feature keeps water from freezing in the pipelines during cold snaps. It also permits the installation of restrictors on sprinklers without stopping the water flow, allowing water and foam to be supplied simultaneously throughout the protected area.

However, there are some exceptions. To shorten the time it takes to supply extinguishing agent for fire extinguishing, pipelines are partially filled with water in the event of a potential explosion in a fire, constant plus temperature, or rapid fire spread.

Control system.

Intended to produce control signals among the fire extinguishing system’s component parts in order to deliver fire extinguishing agents to the protected areas. Additionally, for alerting staff members at the facility as well as fire and rescue services to the presence of a fire.

Sensors to detect the primary fire factors.

First of all, a manual start/extinguishment mechanism for the drencher system is required. Incentives also come in four varieties:

1. Electric. In conjunction with the fire alarm system, the extinguishing system responds to smoke, fire and temperature sensors. Which creates an impulse to open the valves and start the pumps to supply the extinguishing agent.
2. Cable. It is used on objects with constant temperature above 0 0C. The rope with thermal locks is stretched in the protected room, after exposure to temperature, the thermal lock activates the rope, which opens the gate valve for water and foam supply.
3. Hydraulic. A thermal lock is installed on a certain number of pipelines filled with extinguishing liquid. When the thermal lock is triggered, the pressure in the system drops and pumps are switched on to supply the extinguishing agent to the protected room over the entire installed area.
4. Pneumatic. Part of the piping in the protected room from the thermal lock to the valve is filled with gas. When the thermal lock is triggered, the gas pressure drops, which leads to the opening of the valve with the subsequent start of pumps and extinguishing the fire in the area of the room.

Drenchers or sprinklers (sprayers).

A single drencher fire extinguishing sprinkler is intended to cover a 9 m2 area. The distance between the drains themselves and the wall should be 3 m and 1.5 m, respectively, for the best extinguishing and protection.

The structural structure separates the drains into two categories:

1. Vane, used in the diaphragm (the diameter of the outlet opening is 12 mm);
2. Rosettes, used to create a water curtain (the diameter of the inlet can be 10 mm, 12 mm, 16 mm).

Calculation of the fire extinguishing drainage system

When all the drains are included, the hydraulic calculation serves as the foundation for the ASPT project. Both the primary and backup sources are turned on in this situation. The PPB contains minimums that must be met:

• from 0.1 or 0.3 l/sec (for objects with easily flammable materials) per 1 m. sq. rooms.

• supply line – from 3 m/sec, distribution line – 10 m/sec.

A single sprinkler can cover an area of no more than nine meters square, and the main pump’s needed capacity must be between 100 and 600 meters of cube per hour.

Example of system calculation

The hydraulic computation displays the number of drains and the amount of water used. Experts perform the computations, and the information is documented in the TD, project, and inspection reports. Essential:

1. find out the pressure loss;
2. Consider the hydraulic resistance, irrigation epub;
3. determine the capacity factor.

Calculation simplified for 70 square meters:

1. flow rate of one nozzle at 0.16 MPa – 1.4 l/sec;
2. the diameter of the pipes is 32 mm;
3. total flow rate – 13.2 l/sec;
4. about 7 – 9 drains will be needed.

Installation rules and calculation example

The amount of water needed to put out the flames is used to calculate how to install a drencher fire protection system. The components of the object that needs to be protected determine how much water is needed. Therefore, the standard rate of water volume increases threefold in the presence of large amounts of rubber or cellulose.

When determining the cost of installing a drainage system in a typical room, the following guidelines must be followed:

• one drainer can treat an area of 9 square meters;
• the distance between the drains – 3 meters, the distance between the drains and the wall – 1.5 meters;
• The volume of water used must be at least 0.5 liters per second per 1 square meter of the room;
• The speed of water flow through the supply pipelines should be at least 3 meters per second, and the distribution line – at least 10 meters per second;
• installation is carried out on door, window and technological openings through which the flame can penetrate into the neighboring room;
• to create water curtains it is necessary to use socket-type drains with the diameter of the drain hole of 10, 12 or 16 millimeters, and for direct extinguishing of the flame it is necessary to use vane-type drains with the diameter of the hole of 12 millimeters.

Types and types

There are two types of automatic drainage systems, depending on the extinguishing agent:

• Water fire extinguishing systems equipped with drencher sprinkler heads are more powerful than sprinkler systems for suppressing class A fires (wood, processed products, including cardboard, paper) inside warehouses, production facilities.
• Foam fire extinguishing units are in demand for extinguishing class A fires, which are difficult/impossible to extinguish with water, such as rubber, other polymeric materials, and class B – flammable liquids, including products of hydrocarbon raw materials, technological processes of organic synthesis.

Because of this, drainage units—which are the most efficient automatic means of putting out fires—as well as the cost and intensity of the foam supply that enable prompt and effective suppression of class B fires are widely used for the protection of stores, warehouses of oil refinery finished products, and chemical plants.

In addition to providing property protection, drainage systems are actively used as fire water curtains, acting as fire barriers, dividing into building compartments or fire sections of a significant area or volume, and replacing fire screens, curtains, gates in technological openings in buildings, open vestibules, and process equipment housings. They also serve as emergency cooling equipment and storage tanks for flammable gases and liquids.

Principle of operation and constituent elements

It is a branching system of pipelines where water is continuously under pressure. As soon as a fire breaks out, the network must respond immediately. Consequently, the sprinkler system consists of:

1. Pump-jockey, which maintains the pressure inside the network. It"s small in capacity and volume. It is not tasked with delivering the amount of water required to extinguish a fire. But it can be used to extinguish a small fire.
2. The main pump, which provides the required volume of water. Their number is determined by the branching of pipelines and the number of sprinkler irrigators.
3. Pipelines connecting the pumps and sprinklers.
4. The sprinklers themselves.

How this plan operates. The sprinklers are crucial, or more specifically, their thermal lock, which supports the valve that seals the holes. A unique heat-expanding liquid is pumped inside a hermetically sealed glass flask, which serves as the lock. The liquid expands in volume due to the fire’s rising temperature, pressing on the glass inside the flask and breaking it. The water supply is opened by the bulb bursting.

The latter starts to sprinkle through tiny holes as a result of the jockey pump’s pressure. If multiple glass flasks explode due to the room’s rising temperature, the jockey pump can handle the situation on its own because it has the necessary amount of water in it. However, if the fire gets too big, meaning that a lot of sprinklers are turned on, the main pump kicks in to provide the fire extinguishing system with the necessary amount of water.

The network also incorporates essential signaling, such as light and sound alerts. Alternatively, different containers that hold the necessary amount of water can be used. The pumps are linked to the water supply line if the facility is small.

Varieties of fire sprinklers

More discussion of the sprinkler is required because it is a key component of the fire sprinkler system. Dealing with thermal locks, or glass flasks, must come first. Size-wise, they are typical devices. But the speed at which they respond varies dramatically. For this reason, the liquids are colored differently by the manufacturers.

Fluid color	Temperature at which the bulb bursts, C	Response speed, min.
carrot	57	2-5
red	68	2-5
yellow	79	10
green	93	10
blue	141	10
blue	182	10

The remaining items fall into the high-temperature category, while the first two are classified as low-temperature elements.

Only one structural component—the socket, which determines the direction of the water or foam spray—distinguishes the models from one another. Three fundamental models exist:

1. Standard, round socket, which creates a stream of irrigation in its own shape in all directions. Manufacturers offer two varieties of water sprinklers of this type: installed with the socket upwards (brand SVV) and with the socket downwards (brand SVN).
2. A visor is installed on the socket to redirect the flow of sprayed water. They are used only if it is necessary to emphasize a particular area, for example, to create water curtains or to provide cooling for process equipment.
3. Sprinkler, inside of which a cap with a large number of small holes is installed on the supply pipe side. It is this cap that creates the water spray of a finely dispersed type. Usually these devices are used in fire sprinkler systems in facilities defined by class "A" fire hazard rating.

Requirements for sprinkler heads

Certain requirements indicate the sprinklers’ quality:

1. Tightness of the device. Since the entire fire sprinkler system is pressurized at all times, any leaks are leaks that will allow water to pour into the interior of the premises. Therefore, this parameter is considered to be the main indicator of the quality of the device.
2. Durability and reliability of the devices. Shock loads, negative impact of aggressive media, humidity and temperature fluctuations – all this irrigators must be able to withstand throughout the entire period of operation.
3. Reliability of the glass bulb. It must burst only when exposed to the required temperature.
4. Intensity of water spraying. Here everything depends on the diameter of the holes, which varies in the range of 8-20 mm.

Requirements for the condition of extinguishing agents

The attitude toward them in terms of pressure created is different because fire extinguishing involves using a variety of substances, such as gases, water, foam, and various water-dispersed solutions, to put out the fire.

• For liquid substances the pressure is not less than 1 MPa (10 atm).).
• For gases – not less than 0.01 MPa.

These are merely suggested values. Technical documentation created during the sprinkler system design phase serves as the foundation for determining real indicators. The documents in this instance must unavoidably state the extinguishing agents’ maximum and minimum pressure values inside the pipelines. The state fire protection authority is in charge of ensuring that the parameters are correctly followed.

STATIONARY WATER INSTALLATIONS

Water was the most accessible and efficient firefighting material when the first stationary fire extinguishing systems were installed.

Water-based automatic stationary fire extinguishing systems are currently employed to put out fires of category "A," which are typically fires involving solid materials that may smolder while burning:

1. Subcategory A1 – raw materials and products made of wood and wood-based composite materials (chipboard, fiberboard, plywood), cellulose, textiles and plant fibers;
2. Subcategory A2 – raw materials and products made of polymeric materials, natural and artificial rubber, bitumen, organic and synthetic resins.

The following are some benefits of stationary water-based fire extinguishing equipment:

Since water doesn’t harm humans like other extinguishing agents do, the extinguishing system can be activated as soon as a fire is discovered without waiting for personnel to be evacuated;

The most affordable kind of extinguishing agent is water. Compared to gas and powder systems, stationary installations utilizing it have comparatively low installation costs and much lower ongoing maintenance costs;

Many changes have been made over time that make it possible to install a stationary water automatic fire extinguishing system in practically any room.

It is also necessary to mention a few drawbacks and technical restrictions.

1. Automatic water-based fire extinguishing units cannot be used to extinguish category B, C, D and E fires;
2. Restriction on operation at sub-zero temperatures. At the moment it can be bypassed by adding antifreeze to the water tank to prevent freezing. However, this does nothing to raise the cost of the extinguishing agent;
3. Water has a negative effect on various material valuables and can damage them as well as fire.

Experts distinguish between the following stationary water fire extinguishing methods based on technical specifications:

Covers the whole protected area when operating. They are distinguished by high water consumption, necessitating large tanks and more potent pumping machinery.

Their efficiency is relatively high and their response time is fast. Nevertheless, they seriously impair finishing materials and property values. Primarily utilized in industrial settings, where their potential for indirect harm is minimal.

Distinguished by specific triggering. Heat locks, which are present in sprayers, are destroyed by elevated temperatures. As a result, the water supply is done exactly in the flame detection zone. The system’s operational efficiency is marginally less than that of a drencher.

Furthermore, the pressurized water in the pipelines makes this system very vulnerable to below-freezing temperatures.

Water extinguishing systems with fine spray.

Agents for extinguishing fires were only recently introduced. characterized by great effectiveness and minimal extinguishing agent consumption, allowing a variety of combustion inhibitors to be added to water or other fire extinguishing agents.

They are authorized to extinguish disconnected electrical installations up to 1000V, produce significantly less collateral damage, and lessen smoke in the space.

In contrast to earlier systems, stationary laphnet barrels are typically operated manually and activated outdoors. They are utilized in public spaces of pulp and paper mills, wood processing industry businesses, etc.

Areas of application of drainage systems

GOST R 51043 of 2002 is the primary normative act that establishes the specifications for the technical features of drainage installations. Several fundamental ideas are introduced in the document:

1. A sprinkler is a device that atomizes or sprays water or a solution of a blowing agent to extinguish a fire.
2. Drencher. drench) is a type of sprinkler, a device that has an open outlet. The fire extinguishing agent, such as water, exits through it.

Installing a sprinkler directly on the pipeline means that it is typically placed beneath the ceiling and not frequently on the walls. Due to its quick fire extinguishing capabilities, the device is frequently utilized in large plants, such as:

• Domestic and industrial chemical plants;
• wood processing plants;
• shops where paint and varnish products are produced;
• Production or storage facilities with permanent negative temperature conditions.

Sprinklers with a dehydrator are also useful in areas where a lot of people are frequently present. These include medical facilities, conference rooms, hotels, restaurants, schools, and other establishments.

Not only do these fire extinguishing devices react quickly to the fire’s source, but they also spray water or a foaming agent simultaneously from multiple points, which contributes to their effectiveness. For this reason, sprinklers are typically installed in big batches all at once.

Device

The general concept of the equipment arrangement and the fundamental makeup of the drainage system’s components is quite similar to that of the sprinkler system. Water is fed into the control unit from the water supply lines and the fire reservoir (reservoir), and pressure is increased through a pumping station on the property of the building protection object or industrial site via installed outdoor technological installations. From there, the distribution network is distributed with mounted sprinkler heads and foam generators of various multiplicities.

An illustration of a drencher water fire extinguishing unit’s schematic

• Drencher control unit, consisting of a basic signal valve, control piping, is installed between the supply and feed pipelines.
• The signal valve is the central element of the control unit, responsible for opening the passage cross-section after receiving the control signal from the fire extinguishing control devices; regulating the water flow; maintaining the required pressure level in the supply pipeline.
• Control bundling of the drainage unit is a complex of shut-off, signal and starting devices, valves, control and measuring equipment, united by a system of pipelines, determining all the working functions that ensure trouble-free operation of this set of firefighting equipment, interconnection with external fire automation systems available at the object of protection.
• Control units, components included in the piping should remain operable after 0.5 thousand hours. actuation cycles.
• Drencher system control unit should be located in the premises of pumping stations, fire stations or in protected heated rooms with air temperature not lower than 5 ℃, with free access for service personnel.
• When control units are located in protected rooms, they must be separated by fire partitions, ceilings with fire resistance limit not lower than EI 45, doors – not lower than EI
• Separate control units, which are placed in special cabinets, can be installed in protected rooms, near them, without fire barriers, with a distance to the fire load of at least 2 meters.
• Control units that are placed outside the premises served by the drencher installation, it is necessary to allocate mesh, glazed partitions.
• A supply pipe connecting the control unit to the fire water supply inlet, or to a fire-fighting pumping station.
• Feeding pipeline connects the control unit with the distribution network of pipelines mounted in the premises of the object of protection, on which are installed drencher water or foam sprinklers, foam generators.
• All pipelines should be made with steel pipes with threaded connections, flanges, electric welding, split pipe couplings.
• Pipelines laid in places inaccessible for visual inspection, maintenance – behind suspended ceilings, in grooves, shafts, should be connected only by electric welding.
• In addition to steel, the norms allow the use of fire-resistant plastic pipes, tested, according to the developed technical specifications.
• It is forbidden to connect technological, sanitary and technical equipment to any type of pipelines of the drainage systems.

• Drencher sprinklers with a fully open outlet opening with a diameter of 10, 12 or 15 mm, designed for spraying water, foam solutions, are installed dissecting the flow of liquid sockets/blades downward or upward, which depends on the design solutions, there are general, special purpose; for water curtains; for the protection of rack storage, suspended ceilings; recessed, concealed, hidden.
• A diverter is the product furthest or highest removed from the control unit.
• Foam generators of different multiplicity, usually used in volumetric extinguishing method.

The following accessories are added to ditcher foam fire extinguishing systems:

• Pumps for filling the tanks with foaming agent.
• Tanks for storage of foaming agent.
• Automatic dosing devices, including diaphragm-type, ejector-type dosing devices, pumps/dosing tanks.
• Drainage for draining the fire-fighting agent from the tank and water solutions from the pipelines.
• To control the level in containers with foaming agent.
• For mixing solutions.

Crucial: installation of foam fire extinguishing systems at the target of safety should have a 100% fire foaming agent reserve in addition to being calculated. It is possible to store both the design and reserve volumes in the same tank.

The installation of a fire alarm system with heat, smoke, combined fire detectors, flame detectors in protected premises, on open technological areas, interlocked through the reception and control devices, and fire extinguishing control units with control units is most frequently used as a standard prompting system for automatic start of drainage systems.

What is the difference from the sprinkler system

The table below illustrates the key distinctions between sprinkler and drainage systems.

Drencher systems	Sprinkler systems
Can be used repeatedly	Must be replaced after the first use
Fill the entire protected area, providing extinguishment and localization of fire	Sprinklers work selectively only in the area affected by fire
Smoke and temperature sensors can be installed	The head of the sprinkler is closed with a thermal lock, when the temperature rises, it opens and the system is triggered
The system mains are filled with air or extinguishing agent, but not pressurized	Pressurized water circulates in the system piping
Response time up to 5 minutes, shortened by the use of an electric starting mechanism	Operation time from 5 to 10 minutes, which is due to the heating time of the thermal lock
High extinguishing agent consumption due to simultaneous operation of all sprinklers	Reduced agent consumption due to selective action of sprinklers

Caution! Because of their larger coverage area, quick operation, and reusability, ditcher units are more sophisticated.

Regulatory documents

Rules controlling the layout, equipment needs, installation, and use of drencher fire extinguishing systems:

• SP 485.1311500.2020 on design standards for fire extinguishing installations, including drainage systems.
• GOST R 50680-94 on requirements to water fire extinguishing systems, GOST R 50800-95 – foam extinguishing systems.
• GOST R 51043-2002 on requirements for sprinklers of water and foam fire extinguishing installations.
• GOST R 51052-2002 on requirements, methods of testing of control units of water, foam fire extinguishing systems.

Application on objects

Water-based sprinkler systems and foam extinguishing agents are frequently employed to safeguard dangerous kinds of establishments. In order to eradicate fire cores at considerable fire intensity, it is imperative to promptly irrigate vast regions and completely fill the enclosed space to put out the fire before it spreads further:

• Production halls of oil refineries, chemical plants.
• Woodworking facilities.
• Warehouse complexes, including fuel and lubricants warehouses, oil depots.
• Paint and varnish production enterprises.

In addition to other items, such as those that function without heat.

Drencher water curtains are used to separate large, volumetric construction objects into fire compartments and to safeguard technological openings, vestibules, and construction sites.

Advantages and disadvantages

Users who select fire extinguishing drains receive:

• fire protection for large areas
• the fastest response time after switching on compared to a sprinkler system;
• the ability to prevent smoke, soot, carbon monoxide and toxic fumes from spreading throughout the room;
• equipment that switches on and off independently, reacting to the signals of sensors at switching on and the volume of used fire-extinguishing agent for switching off (the volume is set based on the area of the room from 15 to 200 liters);
• reusable without additional costs for refurbishment, refilling of the system or replacement of individual parts;
• the possibility, at low cost, to transfer the installation to work with another substance, for example, with foam or gas.

There are some drawbacks to the system, including:

• use of a large volume of water or foam, sometimes unjustified;
• water damage to property;
• The possibility of erroneous actuation to neutralize, which requires the use of several different types of alarms.

System requirements

Drencher fire extinguishing systems are intricate engineering installations that require adherence to several regulations during installation.

These specifications relate to:

• The location of the drains in relation to the space and to each other;
• water consumption rates;
• quickness (the moment of switching on);
• Speed of water supply during extinguishing.

Kindly take note! The maximum technological area that each drainer can protect is limited to nine square meters. м. They are all located within the system no more than three meters from each other. There are no walls or other physical obstacles within 1.5 meters of it.

In order to guarantee the formation of a dependable water curtain and the extinguishment of fires of varying intensities, the system’s standard water flow rate should be set at 0.5 liters per second for vertical surfaces and 0.1 liters per second for horizontal coverings per square meter of protected area. If the room is used or stored with materials that generate a lot of toxic waste, like rubber or celluloid, the flow rates are raised to 1.5 and 0.3 liters per second, respectively.

The necessary piping capacity has been determined. Water must be able to move through the distribution pipes at a maximum speed of 10 m/sec and through the supply pipes at 3 m/sec.

The specifications for the fire extinguishing systems’ capacity are established based on the area and intended use of the premises.

• increased capacity – an hour of operation during operation is provided;
• average capacity – the working cycle is 30 minutes.

Larger diameter piping needs to be installed when foam is utilized as the fire extinguishing element instead of water.

Norms and regulations

Drencher fire extinguishing systems are automatically operated and governed by all fire safety rules and regulations.

These are some of the most pertinent regulatory documents:

• Code of Regulations SP 5.13130.2009 on automatic fire extinguishing and alarm systems;
• NPB 88-01 on the norms and rules for the design of fire extinguishing and fire alarm systems.

These documents lay out the requirements that the fire extinguishing installation must adhere to, including the following:
