Introduction
Coal fired boiler is a steam or hot water boiler that uses coal as the main fuel. Coal is burned in the furnace, and the heat generated is transferred to water through heating surfaces to produce steam or hot water for industrial use.
Feeding system: manual, automatic
Structure: fire tube, water tube
Design Type: vertical, horizontal
Combustion Type: chain grate, travelling grate, reciprocating gate
