There are two basic types of feeders used in industrial plants: volumetric and gravimetric. As its name implies, a volumetric feeder modulates and controls the volumetric rate of discharge from a bin (e.g., cu. ft./hr.). The four most common types of such feeders are screw, belt, rotary valve, and vibrating pan. A gravimetric feeder, on the ...

For the purpose of calibrating the gravimetric feed control system 30, a test load in the form of a calibrating weight 50 is provided. This load may be applied to the weighing mechanism when the feeder A is not in operation and when there is no coal carried on the upper span 28 of the belt 21.

Stock Gravimetric feeders provide coal delivery on a weighted basis in order to more closely match the combustion control requirements for heat input into the boiler. The Gravimetric Feeder automatically compensates for density variations and feeds coal to …

and two test laboratories that offer free testing of customer-supplied materials using Metalfab's equipment and systems. With more than 30 years of application knowledge and material handling systems design experience, Metalfab's installed base comprises thousands of bin activators, gravimetric and volumetric feeders,

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 to the

A loss-in-weight feeder is a gravimetric feeder that directly measures the material's weight to achieve and maintain a predetermined feed rate measured in units of weight per time. The following section ( The Gravimetric Feeding Triangle ) …

Gravimetric dosing systems, on the other hand, use one or more integrated weigh cells to measure input material. This means that mass is the only parameter considered. Because the system continues to dose material until it reaches the …

Comprehensive coal feeding solutions. Stock has supplied coal feeding and material handling equipment to power plants since 1929. The company has developed an excellent reputation in the industry, supported by more than 80 years of experience in providing gravimetric and volumetric feeding systems and more than 12,000 feeders installed worldwide.

Gravimetric Feeders The feeder was typically located immediately beneath the coal bunker and immediately over one of the pulveriz-ers. Coal would pass down into the feeder and onto the horizontal transfer belt within the feeder body. As the coal proceeded from the inlet and toward the discharge, it passed

As the micropulverized coal fills the feeder hopper 8 on the gravimetric feeder 12, its level is sensed by a level detector 9. See also FIG. 3. When the sensor indicates that the coal has filled the hopper to a predetermined level, a signal is sent to the computer 201 (FIG. 3) via a digital data input/output board 202 which causes the two speed ...
