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.
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.
