Referring more particularly to the drawings and initially FIGS. 1 and 2, there is shown a gravimetric coal feeder A adapted to receive a column 10 of particulate coal through an inlet conduit 11, from a hopper 12. The apparatus A feeds the coal from the column 10 at a controlled rate of flow to a discharge chute or conduit 13 at the righthand ...
Precise feeder control and minimal stoppages above and below the feeder are crucial. Hot smoldering or burner raw fuel anywhere in the pulverizer system is considered serious. Raw coal that is allowed to "spill" into the under bowl (air inlet) section and is allowed to accumulate will be exposed to high temperature (usually 500°F or higher ...
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.
For maximum fuel efficiency and low emissions levels, you need a precise and consistent coal feed. The PFISTER® SCF delivers. Thanks to the integrated dosing electronics, this smart coal feeder provides highly accurate and reliable gravimetric feeding of pulverized fuels to the burning process, including coal dust, lignite dust and petcoke.
Interruptions in raw coal feed. Lower feeder speeds. This occurs because a minimum airflow through the coal mill must be maintained to insure that burner line velocities are not too low to allow settling of coal in the fuel lines or burner components. Not uncommon to achieve air to fuel ratios of 3 to 5 pounds of air per pound of coal.
configuration while the boiler 10 was fired by coal feeders and four (4) bark chute openings evenly spaced above the feeders. Boiler 10 was designed to burn stoker coal and wood fuel on an air cooled traveling grate. Both boilers 1 and 2 were designed to generate 110,000 pph of steam flow, while Boiler 10 had an MCR steam flow rate of 225,000 pph.
Boiler Auxiliaries such as PA fan, ID fan,Coal Feeder and Fuel Oil motors can be upgraded with VFD control, for old 210 MW and 500MW units. New units of all sizes should have VFD for coal feeder speed control. VFD is becoming popular for VRV airconditioning, Hoists, Lifts and EOT Cranes 66 THANK YOU. 67 Speed Motor Ratings Major SG ...
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 units.

The crushed coal is fed to the drier from the raw coal bunker by gravity. The drying of coal is effected either by using hot gases, preheated air or bled steam. The dried coal is fed to the pulverizer with the help of feeder. The pulverized coal is carried from the pulverizer mill with the help of air and it is separated in the cyclone separator.
Therefore, DMS methods are widely used in the separation of coal and various metal ores and nonmetallic ores. Direct separate clean coal and waste rock; separate coarse waste tailings and rough concentrate. For the ordinary gravity separation method, the lower limit of the feeding ore is about 23mm (the coal is 36mm).

He then resumed hauling coal from the No. 3 face. When he pulled onto the section feeder with his 3rd load, his shuttle car lost power, also blocking the No. 2 shuttle car from reaching the feeder. After the shuttle cars did not return to the face for loading, the continuous mining machine operator walked toward the feeder.
Coal feeders provide coal to the coal pulverizers (mills) where the coal is pulverized and dried. Dryer coal is easier to pulverize, and less mill power is needed to achieve the same coal fineness. Additionally, with less fuel moisture, more complete drying of coal can be achieved in the mill. This results in increased mill exit
