Oct 01, 2003· Because of the heterogeneity of coal, gravimetric feed systems have a number of advantages over volumetric systems when it comes to achieving optimised combustion in pulverised coal fired power plants, with lower emissions. Gravimetric systems are widely used in the USA, but volumetric feeders predominate in Europe.
Volumetric and gravimetric feeders control system. a gravimetric control system provides a great deal of feedback in the way of alarms . documentation and inventory control . for example, if a manufacturer is required to provide ongoing process docu mentation or validation to customers, then gravimetric control is the only option gravimetric control is the only option vices such as a level ...
In general, the determining factor for the type of feeder you select will be the accuracy level required for your application. If all you need is a constant, reliable flow of material, the less expensive volumetric feeder may be adequate. For precise metering, the advanced control systems found in gravimetric feeders may be the way to go.
The Model 490 NFPA rated gravimetric feeder is designed to meet your needs when feeding a fluidized bed boiler or other system needs requiring a low pressure, sealed feeder. It is designed with the operator in mind to give years of trouble free operation.
Pressurized Gravimetric Feeders. The STOCK® gravimetric coal feeder weighs material on a length of belt between two fixed rollers (span) precisely located in the feeder body. A third roller, located midway in the span and supported at each end by precision load cells, supports half the weight on the span.

A lossinweight 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 ) introduces the three main challenges faced by any gravimetric feeder: material handling, weighing and control.
of the gravimetric feeder led to general industry acceptance and by the mid1960s most large, coalfired boilers included gravimetric feed systems in their design Gravimetric Feeder Description The first gravimetric feeders consisted of six major elements, as follows: Two of twelve feed systems manufactured for Niagara Mohawk

In light of this reality, gravimetric weigh feeders are the better option. These instruments calculate a substance''s total weight, using that value to determine how much coal to feed. 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 ...
A gravimetric feeder adds a weigh system and new control scheme to what would otherwise remain a basic volumetric feeder. In contrast, a gravimetric feeder feeds material by weight and provides closed loop feedback information about the actual weight being discharged over time.
Ralph Hardgrove, a Babcock Wilcox retiree who joined Stock Equipment Company in 1961 (at 70 years of age), led the feeder''s development into general industry acceptance by the mid1960s, when most large coalfired boilers included gravimetric feed systems in their design.
