superhighmoisture coal. As drying for highmoisture coal requires more heat at a mill, the hightemperature gas at the mill inlet must be applied. Supposing that the moisture content in pulverized coal at the mill outlet is 30%, the gas temperature required at the mill inlet is considered to be approximately 450°C.
