Dew Point Grinding - ME Mining Machinery

Coal Grinding Dew Point Reduction. All modern power-station boilers burning coal are fitted with air heaters. These are used to reduce the temperature of the stack gases to the lowest possible level. This limit is set by the dew point of the water vapour and sulphur oxides in the gas. The higher the percentage of oxides of sulphur
