  • Air Pre-Heater - an overview

    In large steam generators using low-grade coal, with 33–45% ash content, collection and disposal of ash poses a serious problem. In a typical 500 MW coal-fired unit production of ash per diem varies from about 3.0×10 6 kg to about 5.0×10 6 kg, depending on the quality of these low-grade coals. Coal ash may be broadly classified into three ...
