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.

Stock Coal and Limestone Feed Systems

The Gravimetric Feeder compensates for the variation in bulk density by feeding a fixed weight of coal in response to a boiler demand. This ability to accurately weigh the coal on an “as-fired” basis provides significant improvement over volumetric feeders in terms of matching the BTU delivered by the feeder

Weight-sensor calibration for gravimetric coal feeder Justia

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.

Gravimetric analysis Wikipedia

Gravimetric analysis describes a set of methods used in analytical chemistry for the quantitative determination of an analyte (the ion being analyzed) based on its mass. The principle of this type of analysis is that once an ion's mass has been determined as a unique compound, that known measurement can then be used to determine the same analyte's mass in a mixture, as long as the
