Apr 01, 2017· Drag Chain Coal Feeders. Sunit ConCranes made Coal feeders having generally same advantages as mentioned in above conveyors addition to that it delivers a constantly variable but controlled quantity of coal to pulverizing mills.
gravimetric feed systems represent the standard for coal feed systems. Volumetric / CVF For those applications where weighing the coal is not desired. Stock volumetric feeders are designed to reliably and safely deliver coal to the boiler and are built in the same tradition as the Stock gravimetric feeder. They are both built to deliver
Jun 19, 2018· Feeders are useful to handle bulk solids. There are two forms of feeders and we call them as gravimetric feeders and volumetric feeders. A gravimetric feeder consists of a volumetric feeder associated with a weighing system. It measures and controls the discharge of a substance at a constant weight per unit 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.
The Gravimetric Concept A gravimetric feeder adds a weigh system and new control scheme to what would otherwise remain a basic volumetric feeder. In doing so direct measurement and control of discharge rate becomes possible.

Because of the heterogeneity of coal, gravimetric feed systems have a number of advantages over volumetric systems when it comes to Gravimetric Coal Feeder . More Details. gravimetric coal feeder system in indonesia.
This heat generation plant in Lanzhou City employs Smart Coal Feeder Pfister® SCF for dosing coal dust to the burner. The dosing rate is layed to 4 t/h. At another plant in Suqian which generates steam two Smart Coal Feeder Pfister® SCF units are installed with a momentary feed rate of tph each.
The effect of moisture on coal has been studied for many years by Schenck Process LLC, and the resultant density changes are measured by the Gravimetric Feeder. The gravimetric feeder compensates for the variation in bulk density and feeds a fixed weight of coal .
Is a gravimetric belt feeder. The unit accurately feeds free flowing color and additives at the throat of extrusion, blow molding and injection molding machines. The system incorporates a special algorithm that filters out vibrations and movement from mold clamping making it suitable for use on injection molding machines.

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 primary application of Gravimetric coal feeder is for feeding coal to boilers. However, it is used for any solid fuel feeding to boilers. No pressure, NFPA 85 conditions or even higher pressure inside the coal feeder chamber can be variants in the design of feeders.
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 ...
