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

Method of reducing high temperature slagging in

Boiler derations of 10% of total generating capacity due to slagging are not uncommon, and in some cases deration of 25% or more is required to avoid boiler shutdown. While reduction in load is an effective solution to the slagging problem, it is economically undesirable for the obvious reason that equipment is not being used to maximum capacity.
