Abstract

PURPOSE:To obtain briquette capable of readily molding powdered coal by working tar content as a binder and having large mechanical strength and reduced laminar peeling, by directly under pressure molding powdered coal produced by rapidly heating low grade coal while maintaining reforming temperature. CONSTITUTION:High-temperature powdered coal produced in process producing heat treated coal by rapidly heating low grade coal at about 300 deg.C reforming temperature is caught with cyclone and then molded under pressure while maintaining reforming temperature and spontaneously produced tar content is permeated between powdered coals in good fluidity and worked as a binder to provide the aimed briquette. Dusting, absorption of water and autogenous ignition can be reduced and handling properties of coal is improved by molding finely powdered coal using the above-mentioned method.
