    Weightsensor Calibration For Gravimetric Coal Feeder

    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.

  • Should coalfired power plants use gravimetric feeders

    Should Coalfired Power Plants Use Gravimetric Feeders

    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.
