Problems solved by technology

[0003] Therefore, there are currently crop straws, livestock and poultry manures and other fuels that are prepared into biomass fuels that are easy to store on the market. Now most biomass fuels are prepared by crushing straws into segments through a pulverizer, and then extruding them through a molding machine. Molded, shaped biomass fuel will produce smoke due to incomplete combustion during the combustion process, which is harmful to human body and environment

Abstract

The invention discloses crop straw biomass fuel and a preparation method thereof. The crop straw biomass fuel comprises, by weight, 100-150 parts of crop waste, 40-60 parts of pine and cypress branches, 25-45 parts of livestock manure, 5-10 parts of asphalt, 35-42 parts of clay, 30-40 parts of medicine mud sediment, 25-45 parts of coal dust and 5-10 parts of solid alcohol; the crop waste comprises, by weight, 70-90 parts of rice stalk, 20-30 parts of rice husk, 50-70 parts of corn stalk, 30-45 parts of corncob, 35-45 parts of cotton stalk, 5-10 parts of cotton stalk husk and 5-15 parts of peanut shell; the granularity of the crop waste, the pine and cypress branches and the livestock manure is less than 5mm; the granularity of the asphalt, the clay, the coal dust and the solid alcohol is less than 1mm; water content of the biomass fuel is controlled between 6%-8%.

Description

technical field [0001] The invention relates to a renewable energy source, in particular to a crop straw biomass fuel and a preparation method thereof. Background technique [0002] As some renewable fuels such as crop straws and livestock and poultry manure, due to their relatively low calorific value and relatively large volume, they are not suitable for occasions with high heat requirements, so people generally use direct incineration in the field to discard them. Fossil energy such as coal, oil, and natural gas with high calorific value will gradually be exhausted with the large-scale exploitation of human beings. [0003] Therefore, there are currently crop straws, livestock and poultry manure and other fuels on the market that are prepared into biomass fuels that are easy to store. Now most biomass fuels are prepared by crushing straws into segments through a pulverizer, and then extruding them through a molding machine. Shaped, shaped biomass fuel will produce smoke ...
