CFD based investigations into optimization of coal pulveriser
In coal-fired power plants, the first major component is pulverizer, whose performance dictates the total power station efficiency. Pulverizer is employed to grind the lumped coal and transport the fine coal powder to furnace chamber for an efficient combustion. Optimization of the pulverizer at its best operating conditions can be Pulverizer “capacity” is the amount of coal a pulverizer can grind at a given raw feed rate, to a given fineness, at a certain Hardgrove Grindabilty Index (HGI), and at a specific raw fuelPulverizers 101: Part II POWER Magazine

CFD based investigations into optimization of coal pulveriser
In coal fired power plant, coal is pulverized in a pulverizer, and it is then transferred to boiler for combustion. Coal need to be ground to its desired size to obtain maximum combustion efficiency.The experiments have been carried out at a 200 MW and a 300 MW coal-fired utility boiler, respectively.For the 200 MW boiler, the tilting fuel and combustion air nozzles including five primary air nozzles and seven secondary air nozzles are located in each corner of the furnace.All nozzles can be tilted in a vertical direction over ±20° from On-line monitoring the performance of coal-fired power
