PFISTER® rotor weighfeeders are gravimetric, meaning that the coal is weighed as it is dosed, so variations in size and density don''t have the same impact on dosing accuracy. The precision you can achieve with a PFISTER® rotor weighfeeder can have a huge impact on the economical and ecological operation of your plant.

Function of Gravimetric Coal Feeder Guide: The coal feeder can continuously and accurately feed coal, and the amount of coal can be known Taking thermal coalfired boilers as examples of coalfired power generation, the use of coal feeders can stably control the overheating temperature, reheating temperature, and pressure
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. These instruments ...
gravimetric feeding control. A sidebar reviews gravimetric feeding basics. G ravimetric feeders are commonly used to feed bulk solids in the chemical, pharmaceutical, food, and plastics industries. Unlike a volumetric feeder (such as a screw feeder), which feeds material by volume, a gravimetric feeder feeds material by weight. In both. Get Price
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.
