coal power plant slagging

The No 1 cause of furnace slagging is low furnace oxygen content Most boilers are designed for 115 to 120 theoretical combustion air This is generally expressed as 15 to 20 excess air For coal furnaces the oxygen levels would be 3 to 38

Slagging and Fouling in Coal Fired Boilers
Slagging and Fouling in Coal Fired Boilers

Coal fired boilers experience deposition and slagging depending upon the ash characteristics of ash in the coal being fired In many cases the operating parameters also play a major role The molten or partial melting pasty ash deposits in radiant heat transfer surface like boiler furnace is termed as slagging
