Coal Feeder Load Cell Calibration Procedure Automation

2010-6-30  The weights must be able to go to at least 80% of the capacity of the installed load cell. The type of calibration and kit will depend on your application and if it is possible to remove the installed load cells or not. Another easy and relative inexpensive way it can be done is to use water bags, because 1 liter of H2O = 1 Kg in weight so 1000

Gravimetric and Volumetric Coal Feed Systems for Boilers

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.
