Boiler Deslagging: Anti-Slagging Technology for Coal

Boiler Slagging. Power boilers experience slagging as the molten ash adheres to the surrounding substrates. This is also commonly referred to as slag. The amount of slag is primarily dependent on temperature and the types of coal being used and whether it is anthracite, bituminous coal, subbituminous coal, or lignite. Boilers will often slag in

Boiler Slagging

Boiler Slagging . Slagging Propensity. The root cause of furnace slagging is actual very simple, slagging will occur if furnace exit gas temperatures (F.E.G.T.) exceeds the fusion temperature of ash from the coal being fired. To ensure operation without slagging, we typically recommend that F.E.G.T. be 100°F to 150°F below the ash softening

Slagging in PC boilers and developing mitigation

2014-1-1 · Slagging phenomenon is a common problem for a significant number of coal-fired boilers. Coal ash deposits typically form on the waterwall tubes, plug the lower regions of the finishing superheater and superheater areas and lay down on the slope of the nose region of the boiler ().The slope and superheater areas sometimes covered with heavy ash deposits, resulting in undesirable unit shutdowns.
