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 temperature.Get Price
