Coal-fired watertube boilers are classified into three major categories: stoker-fired units, PC-fired units, and FBC boilers. Stoker-fired boilers include a mechanical system that is designed to feed solid fuel into the boiler. These stokers are designed to support the combustion process and to remove the ash as it accumulates.
