BIOMASS SOLID FUEL AND MANUFACTURING METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To obtain higher calorie than conventional so that calorie is 4,000 Kcal or more by mixing bamboo charcoal powder with sewage sludge, maintain such high calorie over long time and further make the ash content after firing extremely low with 30 vol.% or less in the total solid content.SOLUTION: There is provided a biomass solid fuel having calorie of 4,000 Kcal or more and the ash content after firing of 30 vol.% or less in the total solid content by mixing bamboo charcoal powder with sewage sludge for solidification.
