Coal Grinding - Cement Plant Optimization

Mill Feeders: Feeders for coal mill are generally installed directly under hoppers with rod gate in between. The feeders are generally 2 to 3 m long and discharge on to conveyor or feeding chute to mill. For coal mill feeding, table feeders, belt feeders, chain feeders and weigh feeders have been used.

Coal Based Fuel Feeding System for Boiler

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 is the primary process in the thermal power plant. In power plants, the PA fans supply air for conveying of the pulverized coal from coal mills to the furnace area.

Review of control and fault diagnosis methods applied to coal

For an individual mill, MPC block adjusts bias values of the control loops for the coal feeder speed, air flow, and the outlet temperature using estimated values based on the dynamic coal mill model. It is demonstrated that an improvement in the dynamic response, tighter and faster control, is achieved by applying this technique.

Gravimetric and Volumetric Coal Feed Systems for Boilers

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.
