Background
Biomass fuel: the biomass material is burnt to be used as fuel, and is mainly agricultural and forestry waste (such as straw, sawdust, bagasse, rice chaff and the like). Mainly distinguished from fossil fuels. In the current national policy and environmental protection standard, the direct combustion biomass belongs to a high-pollution fuel, is only used in a rural large stove and is not allowed to be used in a city. The application of biomass fuel, which is actually mainly biomass briquette fuel (BMF), is a novel clean fuel which is prepared by using agricultural and forestry wastes as raw materials and performing the processes of crushing, mixing, extruding, drying and the like to prepare various briquettes, granules and the like and can be directly combusted. After the biomass fuel is produced, a lot of powdery substances usually exist, the existence of the powdery substances influences the combustion utilization rate, and the raw material conversion rate of the biomass fuel is also reduced.
