    2 Anthracite Coals: ... The boiler uses particles of culm crushed to go through a mm screen. The culm is burnt in a fluidised bed, being stockpiled in tonne quantities prior to burner entry. The steam produced is at 90 bar, 513oC. The saturation temperature of steam 90 bar is, from steam tables, just over 300oC, so the extent of superheating is major. Also in Frackville is a .
