Abstract

The invention relates to the technical field of modern agricultural industry, and discloses crop biomass fuel with high heating value. Crop biomass fuel raw materials are mixed, and auxiliary raw materials are added, so that the burning efficiency is improved; meanwhile, a prepared burning catalyst is added, so that a burning process is promoted, the burning area can be enlarged, the burning speedis improved, the burning process is more complete, the heating value are higher, the complete burning performance is improved, the residual ash content after burning is reduced, the biomass fuel havean adsorption effect on polluted gas, and pollution of the gas exhausted by burning is reduced. According to the crop biomass fuel with the high heating value disclosed by the invention, the problemof low burning heat value of crop biomass fuel is solved, the utilization value of the crop wastes is improved and the heat value of the biomass fuel are improved, and resource maximum utilization andrealistic meaning of environment protection can be realized, and therefore, the crop biomass fuel are very worthy of being popularized and used.

Description

technical field [0001] The invention belongs to the technical field of modern agricultural industry, and in particular relates to a crop biomass fuel with high calorific value. Background technique [0002] Biomass fuel: refers to the burning of biomass materials as fuel, generally mainly agricultural and forestry waste (such as straw, sawdust, bagasse, rice bran, etc.), which is mainly different from fossil fuels. In the current national policy and environmental protection standards, direct combustion of biomass is a highly polluting fuel, which is only used in large stoves in rural areas and is not allowed to be used in cities. The application of biomass fuel is actually mainly biomass briquette fuel, which uses agricultural and forestry waste as raw materials, and is made into various shapes (such as lumps, granules, etc.) through crushing, mixing, extrusion, drying and other processes. A new type of clean fuel that can be directly burned. [0003] As a wide source of c...
