How to improve the combustion efficiency of biomass heating boilers

04 Dec, 2021

　　Under the influence of national energy conservation and environmental protection policies, heating boilers generally use biomass fuels. Biomass heating boilers are boilers that use biomass pellets to provide central heating. The annual production of biomass energy far exceeds the total energy demand of the world. , Equivalent to 10 times the world's total energy consumption, so the use of biomass heating boilers in winter is of great significance.

　　In order to make the boiler energy-saving, it is necessary to improve the combustion efficiency of the biomass heating boiler. Like other boilers, to improve the combustion efficiency of the biomass heating boiler, it is necessary to ensure that there is no slagging in the furnace and the boiler has a faster combustion speed. , The following introduces you to the measures to improve the combustion efficiency of biomass heating boilers:

　　1. Sufficient oxygen: If the excess air coefficient is too small, that is, the air supply is insufficient, it will increase the solid incomplete combustion heat loss q4 and the combustible gas incomplete combustion heat loss q3, which will reduce the combustion efficiency; if the excess air coefficient is too large , It will lower the furnace temperature and increase the heat loss of incomplete combustion. The optimal excess air coefficient makes the sum of q2+q3+q4 the minimum.

　　2. Adopt anti-scaling and descaling technology: By adopting biomass heating boiler descaling agent and electronic anti-scaling device, the water vapor circulation system is optimized, and the boiler's blowdown rate is reasonably controlled, thereby reducing scale and improving boiler thermal efficiency.

　　3. Keep the flame front position of the biomass heating boiler fuel reasonable. The flame front should be located between the high-end grate and the middle grate, and the flame on the grate is full.
