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

Gravimetric Coal Feeder ASME

Earliest known coal feeder, representing innovations that influenced nearly all industries using coal-fired boilers . A variety of mechanical feeders, including drag-chain conveyors and rotary pocket feeders, historically have been used to volumetrically control the flow of fuel to coal pulverizers on power generators. Most power generation in the United States has relied on burning fossil

Stock® HPG feeder High Pressure Gravimetric Feeder

The HPG series is designed for pulverized coal fired boilers that require feeders to withstand explosion pressures as high as 50 PSI (3.5 bar) in accordance with NFPA 85, and provide maximum safety and accurate coal feeding. This feeder has a typical conveying length of 7’ (2134mm) and can be designed as a drop in replacement. Stock®

Should coal-fired power plants use gravimetric feeders?

Substituting a gravimetric feeder with a volumetric equivalent isn't feasible for power plants. Machinery that burns coal to produce a specific amount of energy must not receive an excess or paucity of material. If a pulveriser, for example, receives more coal than it is equipped to handle, the mechanism may break, resulting in downtime and lost productivity.

Pfister® SCF coal feeding from FLSmidth

Based on the industry-proven PFISTER® gravimetric rotor weighfeeder technology, the smart coal feeder is especially designed for dosing pulverized fuels in industrial environments.
