Should coal-fired power plants use gravimetric feeders?

Why gravimetric is optimal Volumetric weigh feeders depend on a material’s consistency in order to perform effectively. As the name implies, these instruments calculate the amount of space a particular substance occupies, and use this estimate to gauge how much product should be fed to conveyor belts. With coal, this approach is problematic.
