Device and principle of operation
Such a device works on a straightforward principle: gas is introduced into the inner cavity at a high speed through an ejector, allowing air to be drawn into the volume and mixed with the gas.
A specialized ignition device is used to ignite the ready gas-air mixture at the openings after it has passed through the distribution tubes and reached the outlet. Most boilers used for home heating use piezo igniters.
- nozzle device;
- igniter or piezo ignition;
- primary sensor that monitors the presence of flame.
In the realm of heating and insulating your home, understanding your gas burner for the boiler is key. This vital component comes in various types, each with its own unique device and maintenance requirements. From traditional atmospheric burners to modern condensing ones, knowing how to clean and maintain them ensures optimal performance and longevity. But with the array of options available, selecting the right gas burner can be daunting. This article aims to simplify the process by shedding light on the types, inner workings, cleaning procedures, and providing guidance for choosing the best one suited to your needs. Whether you"re a homeowner looking to upgrade or a professional seeking insight, mastering the gas burner is essential for efficient and effective home heating.
Types of gas burners for boilers
Burner devices and boiler design are closely related. In order to ensure thermal balance, the boiler manufacturer typically produces it independently or completes it with a strictly defined model.
Such devices cannot be altered or rebuilt because doing so could result in an explosive emergency when the gas equipment is operating.
Grouping gas burner apparatuses:
- atmospheric type, usually used in units with an open furnace chamber of small thermal capacity;
- fan or supercharged for closed furnace, used in powerful boiler units;
- with a permanently operating ignition device;
- piezo ignition.
Furthermore, there are combi-oil burners for boilers that can operate on both gas and oil fuels, such as the GMG burner gas and oil burner.
Fan
These devices rely on energy to function and require forced airborne oxygen supply. These burners’ designs enable a more accurate blending of the two media, resulting in the highest quality combustion process.
Burners are installed in industrial units used for central heating, such as an oil burner for the boiler, and in residential units with a high heat load.
They mostly produce saturated steam on DE 16 14 boilers. Because these medium-pressure devices are automated, you can regulate how they operate. Flame control sensors are present in burners GMG 4 or 4m and burner GMG 5, for instance. A unit of that type will automatically cut off when the flare goes out.
An additional unit in gas oil burners that run on two different fuels cleans the fuel oil of suspended solids and heats it to a temperature of approximately 70 degrees Celsius, lowering the viscosity of the fuel.
Atmospheric gas burners
The boiler operates much more easily because this burner device construction type is the simplest. Air mixing and natural air suction allow them to operate.
Chimneys are used to remove the fuel mixture’s combustion products. They get their air directly from the room, which needs to have three ways of air circulation in the furnace room, as well as adequate supply and exhaust ventilation.
The primary benefit of such devices is their energy-independent operation, or their ability to run without a power source. Due to their poor ability to mix gas and air efficiently, they have the lowest efficiency of all the models that are currently on the market.
Diffusion kinetic
A midway version between ventilator and atmospheric devices is the diffusion-kinetic device. Their primary application is in industrial gas boilers.
Units that use both fuel types—gas and fuel oil or heating oil—are equipped with combined burner devices. They are thought to be more effective, feature safety automatics, and have a good range of unit load regulation from 15 to 105%.
Classification by the method of air supply
The device’s ability to operate efficiently depends on the quantity, quality, and supply of gas and air mixed together; this will also determine whether the device can meet its efficiency and heat output normative indicators.
Devices for air supply are organized as follows:
- Blowless – air masses are supplied to the burner mouth due to rarefaction in the furnace chamber;
- Injection, in them air flows are drawn to the mouth of the burner for heating boilers, a jet of gas;
- blowing, the combustion air enters the furnace using a centrifugal fan.
Low temperature
Devices of the atmospheric type are mounted in boilers with open furnaces. Their operation operates on a very basic principle. Air is drawn from the furnace room by the ejector device that directs pressurized gas from the mains to the igniter.
A tiny amount of low-temperature flame from the igniter wick causes ignition. Low-power household heaters use this setting. They operate simply, produce little noise, and have a low cost indicator.
Injection burner for boiler
The heat output values of these gas burner designs are higher. Their efficiency stems from the fact that the gas is enriched with oxygen from the surrounding air even before it enters the chamber.
The process of getting the working mixture is divided into multiple steps. This is how a liquid-fuel roof burner operates.
Such a gas burner unit is constructed with several hollow channels, or nozzles, through which high-pressure gas enters and injects (sucks up) air masses that are present in the furnace chamber.
This mixture also goes by the name "micro-flares" because it burns like tiny flares. The pilot nozzle or igniter in the furnace runs continuously. By up to 20%, this model uses more gas than blowing versions.
Blower
Blast fans provide the air for closed furnaces. These burner variations are not all-inclusive; rather, they are computed for a particular boiler, such as a gas burner GGS.
This is a big benefit for the owner of an individual heating system because it comes with the boiler’s basic package and doesn’t require any special installation or adjustment.
The burner unit has the following units installed:
- gas purification filter
- gas pressure regulator;
- gas flow regulator;
- gas reducer;
- primary sensors;
- electric relay for automatic switching off/on of the burner unit according to the boiler setting results;
- electric fan relay, stops the gas supply when the blower motor is switched off.
Because such a system depends on energy, experts advise installing an uninterruptible power supply (UPS) as a backup power source while it’s in use.
How to clean a gas burner
One of the gas boiler’s primary components is the nozzle. Maintaining the cleanliness of the boiler’s working components is essential for the technological process to continue without interruption; otherwise, the boiler’s gas burner will require extensive repairs. These actions are taken when it doesn’t ignite as well as as a preventative measure.
The gas supply has to be turned off in order to clean it.
The algorithm used to remove soot from the burner device:
- Disconnect the ignition button wire.
- The thermocouple clamping device is removed.
- Mark with a marker the level of the nozzle entrance to the burner device in order to install it later in the right position.
- Unscrew the nut that provides the connection between the valve and the device.
- In the same way, disconnect the piezo igniter.
- Remove the nozzle.
- The cleaning process is carried out with a hairbrush and a stiff brush.
- When the fouling is removed, blow out the holes with a vacuum cleaner.
- Next, install the burner in the boiler.
Burner for gas boiler with their own hands
Although it is not difficult to make the burner yourself, experts do not advise doing so, particularly for factory-made boilers where the equipment manufacturer has professionally calculated the gas burner for the boiler.
This procedure necessitates extremely precise calculations because even the smallest mistake could result in inadequate fuel combustion and possibly a boiler explosion.
An atmospheric type gas device may occasionally be installed in a user’s wood-fired, solid fuel unit when there is a viable use case.
Use the ash chamber instead of drastically rearranging the unit to utilize this module. Install automatics for regulatory and control processes. It is preferable to select a burner based on its manufactured heat output.
Selecting an appropriate gas burner for your boiler is essential to guarantee effective heating and peak performance in your house. There are many different kinds of burners on the market, ranging from atmospheric to condensing, and each has pros and cons of its own.
For appropriate cleaning and maintenance, it is imperative to comprehend the gadget and all of its parts. Maintaining your burner through routine cleaning not only increases its lifespan but also lowers the possibility of malfunctions and ensures safe operation.
Think about your needs for heating, the size of your boiler, and energy efficiency when choosing a gas burner. Getting expert advice can help you make the best decision for your house by offering insightful advice.
Recall that while purchasing a high-quality gas burner may seem like a bigger upfront cost, over time it can result in significant energy bill savings. Selecting a more efficient and clean-burning model also lessens the impact on the environment.
In conclusion, the comfort, effectiveness, and sustainability of your home heating system can all be significantly impacted by the gas burner type you select for your boiler.
