Technical Field

the invention relates to the technical field of biomass fuels, in particular to an environment-friendly charcoal-added biomass fuel and a processing method thereof.

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.

In the existing biomass fuel preparation process, a small part of gases such as sulfur dioxide, carbon monoxide, nitrogen dioxide and the like can be generated in the combustion process, and certain damage is caused to the air environment, so that an environment-friendly charcoal-added biomass fuel and a processing method thereof are provided.
