Feb 282015 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 discharge it on the conveyor belt running below. The following points need to be checked before taking any paddle feeder into service.
feed rateif it is not again establish by stopping the conveyor system the problem is identify and attended. This problem majorly occurs in rainy season when coal is in wet condition. Some times operate specially cannot identify the increase current it will cause heavy coal

The method of operation of the feeder by the Coal-trol Digital Thermostat is done at initial setup of the Thermostat. The rst method (TBRN Y on the SETUP menu) controls a Single-Motor feeder by varying the speed of the feeder motor as needed to maintain temperature setting.
Whether operating in a power station stockyard or handling ROM coal on a mineor acting as a bypass unit during major stacker reclaimer maintenance operationsthe new mobile Buffalo reclaim feeder can be loaded by either dozing or side tipping onto the feeding deck at a feed rate of up to 1,800 th through a sizer or directly onto a conveyor
A condition in which the hole above a draw down point for an operating feeder does not manifest at the surface of the coal stockpile. It is also known as domingvoiding and cohesive arches. 1.4.2 Coal placement structures Coal clearance structures used for the support of gantries and the placement of coal onto a stockpile.
Milling System operation. 942013 Steag O&M Company 14 Continue the feeder at minimum speed and establish coal feeding into the pulveriser. Coal fed into mill gets pulverized and carried into furnace thus establishing coal firing. Check for any coal power leakage from coal pipesmills feeder area and attend the same immediately.

Coal needs to be stored at various stages of the preparation processand conveyed around the CPP facilities. Coal handling is part of the larger field of bulk material handlingand is a complex and vital part of the CPP.. Stockpiles provide surge capacity to various parts of the CPP. ROM coal is delivered with large variations in production rate of tonnes per hour (tph).

Volumetric operation of a coal feeder has served the industry for many years. In a volumetric system the flow of material is controlled by the boiler demand systembut the actual amount fed is estimated and the accuracy can vary greatly. Read more. coal mill operation and maintainance scribd.
For all Makes & Models of Coal Feeders Improve plant heat rate Account for fuel use Volumetric operation of a coal feeder has served the industry for many years. In a volumetric system the flow of material is controlled by the boiler demand systembut the actual amount fed is estimated and the accuracy can vary greatly.
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.
Advantages of this feeder design: Large vibrating openingup to 12 x 12permits large hopper discharge openings for greater drawdown volume. Compactlow profile design reduces tunnel depth for substantial savings in foundation costs. Fixed or variable feed rate designs permit continuous operation to assure uniform feed to reclaim conveyor.
