2/2/2019 · Coal Feeder is a device that regulates the amount of coal to be supplied into the Coal Mill. The amount of coal is regulated according to the needs in the boiler combustion chamber (furnace). The number regulation system in the coal feeder can be done in two ways based on the type, namely by weight fraction or coal volume fraction.

The fuel feeding system in a PFBC can be either a slurry feeding or a dry feeding system. In the former, coal and additives (e.g., limestone) are mixed with water and then pumped in the combustion chamber; in the latter, coal is pressurized in a lock-hopper system and then transferred to the combustion chamber via a distribution hopper and supply tubes ( Stubington and Budijanto, 2003 ).

Coal feeding system | Power Engineering
A fluidized bed boiler feed system for the combustion of pulverized coal. Coal is first screened to separate large from small particles. Large particles of coal are fed directly to the top of the fluidized bed while fine particles are first mixed with recycled char, preheated, and then fed into the interior of the fluidized bed to promote char burnout and to avoid elutriation and carryover.
