This paper presents the design of coal bunker with different liner materials The bulk solids flow pattern depends on the flow properties such as angle of internal friction Kinematic angle of wall calculation of bin wall loads feeder loads and normal pressure and rubbing velocities at the boundary walls of hoppers and chutes

Coal Feeder │Instrumentation

The coal is usually stored in the bunker before feeding and the flow of coal is controlled by a gate valve After coal is fed into the feeder it passes through the conveyor belt and enters the coal mill where it gets converted into a fine particle mixed with an equal quantity of air and finally used for combustion inside the furnace
