由于生物质热风炉燃料特性与化石燃料不同，从而招致了生物质燃料在熄灭过程中的熄灭机理，反响速度以及熄灭产物的成分与化石燃料相比也都存在较大差异，表现出不同于化石燃料的熄灭特性。生物质热风炉生物质燃料的熄灭过程主要分为挥发分的析出和熄灭，生物质热风炉焦炭的熄灭和燃尽两个独立阶段，前者约占熄灭时间的10%，后者则占90%，详细熄灭过程如下：生物质热风炉燃料送入熄灭室后，在高温热量作用下，生物质热风炉燃料被加热和析出水分。

Because the fuel characteristics of biomass hot blast stove are different from those of fossil fuels, the extinction mechanism of biomass fuels in the extinction process is induced. The reaction speed and the composition of extinction products are also quite different from those of fossil fuels, showing different extinction characteristics from fossil fuels. The extinguishing process of biomass fuel in biomass hot blast stove is mainly divided into two independent stages: volatile matter precipitation and extinguishing, coke extinguishing and burnout of biomass hot blast stove. The former accounts for about 10% of the extinguishing time, while the latter accounts for 90%. The detailed extinguishing process is as follows: after the biomass hot blast stove fuel is fed into the extinguishing chamber, it acts on high temperature heat. Under this condition, the biomass hot blast stove fuel is heated and water is released.

随后，生物质热风炉燃料由于温度的继续增高，约250摄氏度左右，热合成开端，析出挥发分，并构成焦炭。生物质热风炉气态的挥发分和四周高温空气掺混首先被引燃而熄灭。普通状况下，生物质热风炉焦炭被挥发分包围着，熄灭室中氧气不易浸透到焦炭外表，只要当挥发分的熄灭快要终了时，生物质热风炉焦炭及其四周温度已很高，空气中的氧气也有可能接触到焦炭外表，生物质热风炉焦炭开端熄灭，并不时产生灰烬。

Subsequently, as the temperature of biomass hot blast stove fuel continues to rise, about 250 degrees Celsius, thermal synthesis began, the volatile matter precipitated, and formed coke. The mixture of gaseous volatile matter and high temperature air around biomass hot blast stove was first ignited and extinguished. Under normal conditions, the coke of biomass hot blast stove is surrounded by volatile matter. Oxygen in quenching chamber is not easy to soak into the surface of coke. As long as the extinction of volatile matter is near the end, the temperature of coke and its surroundings in biomass hot blast stove is very high. Oxygen in the air may also touch the surface of coke. The coke of biomass hot blast stove begins. Extinguish, and sometimes produce ashes.
