The combustion method of industrial boilers is one of the factors we will definitely consider when selecting boilers. Let me share it for everyone.
Diffusion combustion
Advantages: This method of combustion is not to pre-mix, but to diffuse the gas at the nozzle mouth, and then burn it. The combustion method is relatively simple, and the flame is relatively stable.
Diffuse combustion
Disadvantages: Due to the long flame, it is easy to produce incomplete combustion, which will produce more carbon monoxide and nitrogen oxides, which is not conducive to the full use of boiler fuel, the improvement of boiler thermal efficiency, and difficulty in achieving boiler emission standards.
2. Full premixed combustion method
Advantages: pre-mixed air and gas, multi-radiator heat transfer, heat transfer intensity is increased. The advantage of using this combustion method is that the burning flame is clearer and the thermal efficiency is higher.
Premixed combustion
Disadvantages: Combustion premixing ratio requires precise combustion rate, fast combustion, sufficient radiant heat transfer efficiency, high flame temperature below 1200 ° C, no incomplete combustion and NOx-generated flue gas temperature, easy condensation, good heat recovery, and high efficiency
3. Flameless combustion
A combustion method that uniformly mixes the space before combustion with the gas in a gas boiler. When using this method, the oxygen required for the combustion of the gas does not need to be obtained in the surrounding air, and it only needs to reach the combustion zone with the air mixture to achieve instantaneous combustion completion.
When choosing a combustion method, you need to compare the advantages and disadvantages of different combustion methods. A good combustion method is also conducive to achieving full combustion of industrial boilers, improving thermal efficiency and reducing emissions. Therefore, it is important to choose carefully.
