How to improve the combustion efficiency of biomass heating boilers

01 Sep, 2021

　　Under the influence of national energy-saving 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, which is equivalent to the world 10 times the 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 increase the combustion efficiency of the biomass heating boiler. Like other boilers, to increase 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 increase 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, and reduce the combustion efficiency; if the excess air coefficient is too large, It will reduce the furnace temperature and increase the heat loss of incomplete combustion. The excess air coefficient makes the sum of q2+q3+q4 the smallest value.

　　2. Adopt anti-scaling and descaling technology: By using 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 increasing boiler thermal efficiency.

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