Pha Lai Coal

Highly pulverised coal is fed through by four tube mills which need no standby provision. This is a consequence of their ability to run for long periods without overhaul. Air is removed from the beds by cyclones which reduce the mass of air and fuel, thus aiding ignition. Circulation is aided by the furnace's octagonal design.
