NOVELTY - A crop straw biomass fuel comprises agricultural waste, pine branch, livestock manure, asphalt, clay, medical mud precipitate, pulverized coal and solid alcohol. The agricultural waste comprises rice stem, rice husk, corn stover, corn core, cotton straw, cotton paper and peanut shell. The particle size of the agricultural waste, pine branch and livestock manure is less than 5mm. The solid particle size of asphalt, clay, pulverized coal and solid alcohol is less than 1mm. The moisture content of biomass fuel is controlled at 6-8%.    USE - Crop straw biomass fuel (claimed).    DETAILED DESCRIPTION - A crop straw biomass fuel comprises 100-150 pts. wt. agricultural waste, 40-60 pts. wt. pine branch, 25-45 pts. wt. livestock manure, 5-10 pts. wt. asphalt, 35-42 pts. wt. clay, 30-40 pts. wt. medical mud precipitate, 25-45 pts. wt. pulverized coal and 5-10 pts. wt. solid alcohol. The agricultural waste comprises 70-90 pts. wt. rice stem, 20-30 pts. wt. rice husk, 50-70 pts. wt. corn stover, 30-45 pts. wt. corn core, 35-45 pts. wt. cotton straw, 5-10 pts. wt. cotton paper and 5-15 pts. wt. peanut shell. The particle size of the agricultural waste, pine branch and livestock manure is less than 5 mm. The solid particle size of asphalt, clay, pulverized coal and solid alcohol is less than 1 mm. The moisture content of biomass fuel is controlled at 6-8%. An INDEPENDENT CLAIM is included for preparation of crop straw biomass fuel, which involves drying agricultural waste, pine branch and livestock manure at 50 degrees C, controlling moisture content of the agricultural waste, pine branch and livestock manure at 20-25%, placing the agricultural waste, pine branch and livestock manure in pulverizer, crushing to obtain particle with size of less than 5 mm, uniformly stirring agricultural waste, pine branch and livestock manure, fermenting at temperature of 55 degrees C for 4 days, adding asphalt, clay, solid alcohol, pulverized coal, medical mud precipitate and 50-60 pts. wt. water to fermented material, stirring uniformly, pressing, further processing and drying until the water content of cake reaches 6-8%.
