COMBUSTION ACCELERATING ADDITIVE FOR NORMAL COMBUSTION OF LOW GRADE COAL MATERIAL AND FORMED COAL USING IT

摘要

PURPOSE: A liquid combustion promoter and molded coal containing thereof are provided to simply manufacture the coal by using cheap raw materials without the pollution problem. CONSTITUTION: A liquid combustion promoter is a hot water extract of a mixture compound containing 11~20wt% of milky quartz powder, 13~22wt% of furnace material silicate powder, 0.3~0.6wt %of ferric oxide powder, 7~13wt% of talcum powder, 4~7wt% of diatomite powder, 17~26wt% of amber powder, and 2.5~7.5wt% of pumice powder. The hot water extract is obtained by adding the mixture compound to boiling water, extracting effective components by boiling before cooling, and filtering.
