Abstract A novel controller for coal circulation and pulverized coal flow in a coal mill is proposed. The design is based on optimal control theory for bilinear systems with additional integral action. The states are estimated from the grinding power consumption and the amount of coal accumulated in the mill by employing a special variant of a Luenberger observer.

An area of power plant control that has received much less attention from mod elling and control specialists is the coal mills. This is in spite of the fact that it is now accepted that coal mills and their poor dynamic response are major factors in the slow load take-up rate and they are also a regular cause of plant shut-down (Maffezzoni, 1986).

Soiled Fuel. Coal is used for burning the raw mill. The coal received from various vendors is stacked at the designated coal shed and quality is checked by collecting the samples manually. The coal is then proportionately mixed if required to get uniform desired quality.

Power plant boiler fuel demand is transmitted as a coal feeder speed demand to a coal pulverizer control. A speed controller operates the feeder in accordance with the speed demand, and a position controller for a hot coal transport air damper positions the hot air damper to hold the mill outlet temperature to a setpoint value and to increase or decrease damper position in …

Pulverized coal mills are typically not equipped with sensors that detect the amount of coal injected into the furnace. This makes control of the coal flow difficult, causing stability problems and limits the plant's load following capabilities.
