ABSTRACT:
A burner combines air cooling and pulverized coal combustion with air for the combustion of low inflammability coals. A ceramic lining protects the cooled steel mantel of the burner while supplying heat for sustained combustion process. Air preheated in the cooling process is used to preheat the coal and to supply secondary air imparting a helical trajectory to the coal particles close to the ceramic lining. The ceramic lining is formed in situ around the flame chamber from molded plastic ceramic hardened by burner operation.
