What are coal feeders? 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.
2. Overview of Gravimetric Feeder Control System Gravimetric feeder weighs material on a belt between two fixed points (span) precisely located in the feeder body (Fig 1). A roller, located midway in the span and supported at each end by precision load cells, supports half the weight on the span.

The gravimetric feeder does this by determining the product of the fuel belt load multiplied by the speed to give the actual flow rate (e.g. tons/hr). This flow rate is compared to the boiler set point and the belt speed is varied accordingly: Gravimetric Conversion Scope: Installing a two loadcell weigh suspension with no moving parts, levers ...
