coal mill control for thermal power plant

Modeling and Control of Coal Mill NTNU

Coal mill is an important component of the thermal power pla nt. It is used to grind and dry the moisturized raw coal and transport the pulverized coal ± air mixture to the boiler. Poor dynamic performance of coal mill will lead to decrease in the overall efficiency of the power plant, slow load take up rate and fr equent shut down.

Coal Mill an overview ScienceDirect Topics

To summarize the coal mill controls, they may be divided basically into two major categories:. 1. To control the quality of coal being sent to the burners located on the furnace walls. The word quality here means the temperature and fineness of the PF. The set temperature values are dependent on the percentage of volatile matter that exists in the main fuel.
