The fuel distribution network feeds a matrix of burners on a wall-fired or a tangentially fired furnace. Each power generation unit at a coal-fired power station can have typically 20, 24 or 32 or 48 burners. A simplified example of the fuel supply and distribution system is illustrated in Fig. 10.1.
Coal-fired plants produce electricity by burning coal in a boiler to produce steam. The steam produced, under tremendous pressure, flows into a turbine, which spins a generator to create electricity. The steam is then cooled, condensed back into water and returned to the boiler to start the process over.
The efficient combustion of coal in large power plant boilers require the proper arrangement of the burners that provide proper turbulence and mixing with the combustion air. To start the combustion, auxiliary burners and ignitors are required . This article describes the three most common burner arrangements - tangential and tilt tangential, down-firing, and wall firing - and the difference
