Feb 02, 2019· 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 ...

Feb 23, 2016· With coal, this approach is problematic. According to Schenck, coal density changes with size, moisture and a variety of other factors. Therefore, even if an operation were processing coal of equal dimensions, each piece may have a different density. In light of this reality, gravimetric weigh feeders are the better option.
Generally, the gravimetric feeder receives the particulate coal in the form of a continuous stream in a fixed flow path, and delivers the coal at a controlled rate as free-falling or separately flowing particles. The rate of discharge by weight is controllable to achieve accurate control of the fuel-air ratio.
A variety of mechanical feeders, including drag-chain conveyors and rotary pocket feeders, historically have been used to volumetrically control the flow of fuel to coal pulverizers on power generators. Most power generation in the United States has relied on burning fossil fuels in steam boilers, with coal as the fuel of choice. By the 1920s, pulverized-firing (the burning in suspension of ...
