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.

Tanjung Coal Fired Jati& B Boiler Design Training Performance.4 Coal Feeders. Coal Feeders receive coal from the Coal Silos and control the amount of coal delivered to the Pulverizers. The Coal Feeder is called a Gravimetric feeder because the feeder weighs the coal as it travels on the belt or conveyor.
For the purpose of calibrating the gravimetric feed control system 30, a test load in the form of a calibrating weight 50 is provided. This load may be applied to the weighing mechanism when the feeder A is not in operation and when there is no coal carried on the upper span 28 of the belt 21.

The gravimetric feeder compensates for the variation in bulk density and feeds a fixed weight of coal in response to a boiler fuel demand. This ability to accurately weigh the coal provides significant improvement over volumetric types in terms of matching the fuel delivered by the feeder to the actual process energy required on coal fired units.
