Improved coal grinding and fuel flow control in thermal ...

2011-4-30 · The grinding power consumption, which is dependent onthe amount of coal on the table, and the di erentialpressure across the mill are well measured. However, themost important information about the fuel ow is typicallynot available. The pulverized coal ow sensors have beenunder development for some time [Department of Tradeand Industry, 2001]. Recent work at Danish power plantsshows that it is possible to use the existing ow sensorsfor the closed loop control. Dahl-Srensen and Solberg presented results on this topic showing how sensorfusion using Kalman lter techniques can be employed toovercome sensor problems and obtain reliable fuel owestimates. The relation between mill's di erential pressure,the primary air ow, and the mass of coal

ANALYSIS OF THE CONDITION OF COAL GRINDING

2013-2-26 · One of the key subsystems in thermal power plants is the coal mill used to pulverize the coal before it gets into the plant furnace. The interior of the mill rotates and the plates located on the inside grind the coal into a small size powder. During that process the plates within the mill slowly get depleted and the productivity of the mill gradually de-creases until it becomes completely dysfunctional (Figure 1). In order to prevent this from happening, the plates need to be changed as soon as the productivity of the mill
