Pulverized coal is portioned out by a gravimetric feeder, and fed to a burner installed at the top of the furnace via a primary air fan. Flue gas passes through a gas cooler and undergoes heat exchange in an air preheater. Fly ash is then removed from the flue gas, and the flue gas is exhausted from a chimney by an induced draft fan. Visual inspection or sampling probe insertion was conducted ...
