COAL MILL SPARES

Coal Mills are used to pulverize and dry to coal before it is blown into the power plant furnace.
In order to control the energy production of the plant, the coal flow into the furnace is a very important factor. Unfortunately, it is not possible to measure the coal flow from the coal mill to the furnace. The coal flow out of the mill is often estimated based on the incoming coal flow. In case of a fault in the coal mill the plant operator would need to take accommodating actions as fast as possible. Fault detection in the coal mill is consequently important.
