What is a smokeless gas boilers – the principle of operation, features of operation

Efficiency and environmental friendliness are our top priorities when it comes to home heating. A novel approach that is becoming more and more well-liked is the smokeless gas boiler. However, what is it exactly and how does it function?

A modern heating system that effectively heats your home while reducing harmful emissions is a smokeless gas boiler. These boilers are designed to burn gas cleanly, which has a significantly lower environmental impact than traditional boilers, which release smoke and other pollutants into the atmosphere.

So, how does this enchantment occur? An extremely basic yet clever principle of operation powers a smokeless gas boiler. These boilers use advanced combustion technology to ensure complete and efficient gas burning, as opposed to older models that burned gas over an open flame.

The ability of smokeless gas boilers to precisely control the combustion process is one of its key features. Through precise regulation of variables like fuel and air mixture, temperature, and airflow, these boilers maximize combustion, leading to negligible waste and emissions.

Their high degree of efficiency is another noteworthy characteristic. Smokeless gas boilers can maximize heat output while consuming less fuel by efficiently utilizing the energy released during combustion. This lowers your carbon footprint in addition to saving you money on energy bills.

What is a smokeless boiler

The term "condensing," "turbine," "closed furnace chamber" boilers, and "smokeless units" refer to the same class of heating apparatus. Residential buildings up to 300 m² in size have units installed for heating purposes. The primary benefits of a smokeless gas boiler are its minimal installation room requirements, draught characteristics, and efficient boiler room ventilation.

The principle of operation of the turbine boiler

• A sealed combustion chamber of closed type is installed inside the device.
• Air intake is carried out through the outer pipe of the coaxial chimney.
• Entering the combustion chamber, the air masses are fed to the burner device.
• Heated air passes through the water circuit, located vertically, providing the best heat exchange.
• After that, the flow containing combustion products is discharged outside the room, through the internal contour of the coaxial chimney.

All smokeless boilers operate according to this general principle. Nonetheless, the consumer’s available units vary greatly in terms of their functional features and design. Smokeless equipment can be categorized using the following signs:

• Place of placement – there are models made in floor and wall-mounted version. The former are characterized by higher power, the latter are more compact. Floor-mounted smokeless gas boiler has more weight, due to the use of thick-walled steel in the production of the combustion chamber. The models are mostly energy-independent, have a simple design and rarely break down. Household floor standing single-circuit boilers are available in outputs up to 40 kW.
  Wall-mounted versions have a lightweight design, due to the use of light metal alloys in the manufacture of the furnace. Economical wall-mounted smokeless single-circuit gas boilers and two-circuit analogs, have a high efficiency up to 90%, and mainly use a system of forced circulation and control of the coolant, as well as the supply and removal of air.
• Functionality – the main purpose of gas equipment is to heat the room. For this purpose, in the design of a single-circuit smokeless boiler is installed water circuit – a narrow copper tube, through which the coolant circulates.
  In two-circuit units there are two tubes or plates at once. In one of them the coolant from the heating system is heated, on the second of them water for domestic needs is heated. Floor-mounted two-circuit smokeless gas boiler has a capacity sufficient to heat rooms with a large area and meet the need for hot water for a large family.
• Type of draught – two-circuit smokeless hinged boilers of the latest generation have a forced system of exhausting combustion products. The operation of the equipment is completely dependent on the availability of electricity. The advantage of the design is high performance and efficiency.
  Boilers with natural air circulation are energy independent. The advantage of the units is their simple design and lack of complex automatics. Boilers work longer than energy-dependent analogs, break down less often, need simple maintenance.
• Ignition type – there are units with mechanical gas ignition, by means of a piezo element or with an electronic system that automatically ignites the gas in case of necessity.
• Performance – modern devices use the principle of condensing heating. In this design, the temperature of waste gases is used for additional heating of the coolant. Atmospheric models have a lower capacity, but are cheaper.

Installing an uninterruptible power supply device with a reserve battery capacity that ensures operation for several hours is necessary to ensure the continuous operation of energy-dependent boilers.

How the flue gas discharge of a smokeless boiler is organized

Coaxial pipes are the only means of discharging the combustion products. This is because of the way the device operates. The chimney’s layout for a closed turbine combustion chamber looks like this:

• The chimney has two circuits. In fact, the design is two pipes of different diameters, inserted one into the other.
• The external contour is used for air intake into the furnace chamber. The air is in contact with the surface of the internal circuit and, as a result, is supplied to the furnace already heated, which increases the thermal efficiency and efficiency of the device.
• The internal circuit is used for the exhaust of combustion products. The temperature of the flue gases heats the surface of the chimney. Cooling is carried out by cold air circulating in the external circuit.

The coaxial chimney’s design is completely safe and cannot start a fire. The header has a wind deflector installed to stop the boiler from blowing out.

A smokeless boiler needs a coaxial chimney. Using a regular pipe as a smoke exhaust system is prohibited.

What is the difference – smokeless and chimney boilers

The principle of flue gas extraction and the design of the combustion chamber are the primary areas where the smokeless gas boiler and chimney boiler diverge.

• Combustion chamber design – in conventional atmospheric boilers an open-type burner is installed. When burning gas, air from the room where the boiler is installed is used. Smokeless units have a closed furnace. Air intake is from the street.
• The principle of gas removal – atmospheric boilers need a traditional chimney, smokeless boilers use a coaxial pipe. Although it is allowed vertical chimney for a boiler with a closed combustion chamber, manufacturers strongly recommend using a horizontal outlet.
• Performance – comparison of chimney and smokeless gas heating boilers is clearly not in favor of the former. Boilers with a closed chamber have an efficiency of 95%, conventional boilers are no more than 80-85%.

A few decades ago, atmospheric units were the only ones used for heating private homes and apartments. According to statistics, smokeless analogs are being installed more frequently these days due to their high heat output and performance.
