What are the characteristics of rice husk granules produced by biomass pellet machines?

Take rice husk as an example to investigate the effect of different rice husk particle size on pyrolysis and incineration characteristics, heat transfer coefficient, and coke incineration. Use TG/DTG6200 thermogravimetric differential thermal analyzer to do heat on rice husk powder of different particle size. After the experiment, different TG, DTG and DTA curves were obtained. The results show that the smaller the grain size of rice husk is, the lower the evapotranspiration point temperature is, and the shorter the time of separation, the greater the heat transfer coefficient and the higher the heating rate, which is favorable for incineration, but the too small particle size increases together. Loss of heat, when the particle size is below the critical standard, easy to show extinguishment. The coke burning process is affected by the size of the particles, the particle size is reduced, the incineration reaction rate is accelerated, and the burning time is shortened, which is favorable for incineration.
Biomass is a kind of aspirational renewable power, because of its extensiveness, reproducibility, and cleanliness. Due to the complexity of biomass, China is a large agricultural country. The annual output of biomass straw is about 600 million tons. It is mainly collected in corn stalk (2817%), wheat straw (2514%) and rice straw (1413%). Biomass research is also about crop waste.
At present, there are many researches on biomass pyrolysis, but there are not many reports on the characteristics of biomass incineration. The shape of the biomass is messy, the density is low, and the calorific value is low, which makes its use difficult. There have been reports of coal and biomass blending techniques and biomass granulation incineration techniques, and there have been few reports of direct incineration of biomass pelletizers. The direct incineration of biomass is primarily stove burning and boiler burning. The use of low-incineration stoves generates low power, resulting in the deterioration of power; the incineration skills of boilers greatly increase the incineration power. The main boiler incineration methods include fluidized bed boilers and layered burners, and the fluidized bed has better adaptability to biomass fuels. The biggest difference between fluidized bed incineration and ordinary incineration is the state when the particles are incinerated. The fluidized bed particles are in the process of fluidized incineration and heat exchange. This incineration method is very suitable for the direct incineration of biomass.
