mill inlet and outlet moisture

Development of Mill-burner System for Low-rank Coal with Super ...

As drying for high-moisture coal requires more heat at a mill, the high-temperature 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. The evaporation of water in raw coal...
