Open all side doors of feeder and empty the coal on belt. Ensure calibration weight is not engaged. Use levelling bars and shim plate ( approx. 0.5mm) to adjust load cells for proper and equal loading between weigh & span rollers. you may check mA at TB 1,2 & TB 3,4 both should be equal mA. After adjustment remove levelling bars.
During feeder operation, coal adhered on the belt is cleaned off by a scraper and dirt accumulated on inner belt is dropped off from both ends of the self-cleansing type tension roll. As seat air also generates dirt, dirt will deposit on the inner floor to cause self-ignition if it is not timely cleaned off.
Where in its operation the Coal Feeder is driven by a 3 phase synchronous motor coupled with a conveyor belt . Coal Inlet: Is a gap or hole …
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
the feeder system of the present invention is a unique combination system for measuring and controlling the mass feed rate of particulate fuel material, such as coal particles, comprising a group of volumetric feeders and a gravimetric feeder coupled to said group of volumetric feeders; and provided with means for controlling the fuel fed from …

Here, the coal feeds into the furnace at the four corners of the furnace. This produces a cyclonic effect in the furnace, ensuring a proper mixing of air and fuel that is essential for proper combustion. Due to this effect, a fireball is created with the burners firing tangential to it.
Drag chain type conveyor thoroughly sweeps the floor of the feeder into the discharge chute to minimize coal and dust build-up. The clean-out chain can be controlled in one of two different modes, either continuously or intermittently …
fCoal Feeders Operation Modes Gravimetric operation weighs the coal as it travels along the belt. This is the primary mode of operation and provides a more accurate measurement of …
Coal is then taken using the reclaimer stacker and then transported by using conveyor 3 to conveyor 4. Coal will then be flown to the crusher house. Inside the crusher house coal is crushed into small sizes of approximately 30mm. In the next process coal is transported by conveyor 5 to flow to the conveyor 6.
The coal going through the feeder is the "Net" weight and that is displayed on the weighing system display. You can do the same with the bags. The bag is the "Tara" weight and the water itself will be the "Net" weight. The weight of the bag can be "Tared' out so that you will have a zero indication before you start filling the bag/bags.

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 …
Highly energy intensive unit operation of coal grinding is intended to provide a fine coal as a fuel for calcination and clinkerization. Coal grinding operation is monitored for following parameters to ensure objectivity and economy of operation. Product fineness (Residues) on 90 …
Smart coal feeder Pfister® SCF with integrated dosing electronics Highly accurate and reliable gravi-metric feeding of pulverised fuels like coal dust, lignite dust, petcoke to the burning process in industrial environments like asphalt produc-tion, heat & steam generation Smart coal feeder Pfister® SCF is based on the industry-wide proven ...
The invention discloses a device for solving the coal clogging problem of a coal feeder. The problem that an existing device is poor in effect of dredging clogged coal is solved. The device for solving the coal clogging problem of the coal feeder is characterized in that the outside of a raw coal hopper, the position above a gate door and the position below the gate …
A belt feeder consists of a hopper positioned directly over a belt conveyor. The belt conveyor "pulls" material out from under the hopper, while an adjustable vertical strike-off plate controls the height of material allowed to advance as the belt moves forward, or in other words, the material profile on the belt.

OPERATION OF PADDLE FEEDER • The Paddle Feeders feed the coal on the conveyor belt from the Track hopper at a controlled rate. The paddle blades projected in the hopper slot scoop the coal from hoppers and …
This feeder has a typical conveying length of 7' (2134mm) and can be designed as a drop in replacement. Stock® HPG feeders maintain accuracy within ± ¼ of 1 percent of the total coal …
Flexibility for your operation The reclaim feeder can be easily relocated to areas of greatest need. Designed to handle a wide range of applications, including coal/coke, aggregates, industrial minerals and other wet, sticky materials. Designed for reliability This unit offer an average in-service life of more than 15 years.
The coal is first crushed into minute particles using equipment called pulverizes. The main function of the Primary air fan or PA fan is to carry the pulverized coal to the furnace as fuel for combustion. This process is used to create the steam that …
The bottom slot opening feeds the material to the belt to deposit the coal symmetrically and centrally to develop an ideal belt loading. The center dome produces a vibratory action on the material to reduce the arching and induce the flow in the storage pile. Sealing is simple and complete with installation of seals as shown in the diagrams.
Operation Of Coal Feeder - greenrevolution. The operation of the feeder is as follows: The coal being elevated by the buckets 8 is delivered to the charge-hopper 1, the deliverygate of which is closed and held by the pressure due to the three weights 20, 27, and 33, the positions of which define this pressure. ...
Guide To Clean And Efficient Operation Of Coalstoker. The coal feed is by either a screw or a mechanical ram which forces the coal the length of the retort and upward. The ash on this type of stoker is normally discharged with side dumping grates. These stokers will fire boilers in the size range of 3,000 to 30,000 pounds of steam per hour.
Coal Feeder is a device that regulates the amount of coal to be supplied into the Coal Mill. The amount of coal is regulated according to the needs in the boiler combustion chamber (furnace).. The number regulation system in the coal feeder can be done in two ways based on the type, namely by weight fraction or coal volume fraction.
