7 Steam Power Plants Dalhousie UniversityPULVERIZED COAL FURNACES Thermopedia

This brief overview on steam power plants focuses on conventional pulverized coal fired power plants PCF PP While the steam cycle section of the power plant is similar for power plants operated on all fuels the fuel handling combustion and post combustion environmental control systems are substantiallyPulverized coal pulverized fuel pf has been fired in rotary cement kilns see Kilns and boiler furnaces see Boilers The latter are basically boxes lined with tubes in which water is evaporated and contain a water/steam mixture

Pulverised Coal an overview ScienceDirect TopicsThermal Cycle and Layout of a Pulverized Coal—Fired Power

The coal preparation building was separated from the boiler house because the plant pulverized the coal and then stored pulverized coal in a bunker for subsequent combustion Coal was passed through Bradford breakers dried to 25 moisture and then pulverized 11 The thermal cycle of a 750 MW size pulverized coal—fired reference power plant is shown in the heat balance diagram of Figure 2 1 The pulverized coal—fired steam generator provides main steam of psia/ 176 F 285 bar/600 176 C and reheat steam of 870 psia/ 176 F 60 bar/600 176 C
