METHOD FOR PREPARING BIOMASS FUEL USING URBAN DOMESTIC SLUDGE

摘要

A method for preparing biomass fuel using urban domestic sludge, comprising: using a coulter blending machine to stir evenly urban domestic sludge, chaff, sawdust, pumice and microbial agent to obtain a mixed material; using a multi-layer vertical mixing and turnover fermentation tower to perform biodrying on the mixed material to obtain a biodried material; and mixing the biodried material with a combustion improver, prilling and drying same to obtain biomass fuel particles. The method is simple and is low in cost, and the prepared biomass fuel has the advantages of igniting quickly, a strong burning fire power and a long burning duration.
