A gravimetric feeder is a self-calibrating feeder system that doses based on the weight in speed. Dosing is significantly influenced by the type and properties of the input material, ambient conditions like temperature, humidity, etc. as well as the type of dosing device. Dosing systems dispense predefined amounts of material in a specified ...

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.
The First Gravimetric Feeder The first gravimetric feeder was manufactured as part of an order for twelve feed systems to be installed at Niagara Mohawk Power Corpora-tion's Dunkirk Station, Units 3 and 4, in 1957. One feeder was completed early to allow for detailed accuracy testing, and was still operating suc-cessfully and feeding within ...
What is special about Pfister rotor weighfeeders for coal power plants? Pfister rotor weighfeeders work like horizontal star feeders. The gravimetric mass in the feeder is measured by a load cell. The speed of the feeder motor is controlled inverse to the mass content in the feeder.
In the 1950s, Arthur J. Stock (1900-1986) successfully combined the weighing and control of material flow into a single device, now known as the gravimetric feeder. The first installation was placed in continuous operation at Niagara Mohawk Power Corporation's Dunkirk Station in 1957. Ralph Hardgrove, a Babcock & Wilcox retiree who joined Stock ...
