NOVELTY - Crushed corn stalk, straw, leaf, peanut shell, cow dung, horse dung and biomass tar as biomass raw material are mixed, crushed and fermented. The biomass raw material is dried using heating source from combustible gas generated by pre-heating and water content is controlled to less than 10%. The dried biomass raw material is pre-heated for 20 minutes at 200-250 degrees C, and portion of volatile component is removed. The pre-heated biomass raw martial is added in cavity (2.1) of compressor mold (2) to compress and obtain biomass fuel block.    USE - Manufacture of coke biomass fuel block used as fuel.    ADVANTAGE - The coke biomass fuel block is manufactured with high density, high carbonation rate, favorable burning characteristics and combustion characteristics, and reduced ash content.    DETAILED DESCRIPTION - Crushed corn stalk (in mass%) (50), straw (10), leaf (10), peanut shell (10), cow dung (10), horse dung (5) and biomass tar (5) as biomass raw material are mixed, crushed to particle size of 1-2 mm and fermented under humidity of 50% at 30 degrees C. The biomass raw material is dried using heating source from combustible gas generated by pre-heating and water content is controlled to less than 10%. The dried biomass raw material is pre-heated for 20 minutes at 200-250 degrees C, and portion of volatile component is removed to reduce volume of the biomass raw material and improve the viscosity. The volatile component in biomass raw material generates combustible gas in incomplete oxidation environment, and the generated combustible gas is used for drying and pre-heating raw material, and used as gas fuel. When the combustible gas is generated, the biomass tar is used as biomass raw material. The pre-heated biomass raw martial is added in cavity (2.1) of compressor mold (2) to compress and obtain biomass fuel block having diameter of 30-60 mm and length of 50-60 mm.    DESCRIPTION OF DRAWING(S) - The drawing shows the schematic view of compressor mold.    Compressor mold (2)    Cavity (2.1)
