To extend the outstanding benefits of the well-proven MAC® system to those boilers that burn poor coals, Magaldi engineered the SuperMAC® system, designed with increased cooling capabilities and a unique system configuration that minimizes the required cooling air amount concerning the total combustion air rate. It addresses the demand of coal-fired power plants for sustainable practices in bottom ash handling when burning high ash content coals (indigenous to India, South Africa, or Mexico) or other low-rank coals (lignite). Unlike conventional wet bottom ash handling (WBAH) systems, responsible for huge water consumption, high maintenance costs, environmental issues, and negative effects on boiler operation, the SuperMAC® dry bottom ash handling system delivers a reliable, cost-effective, and environmentally friendly operation thanks to the unique combination of the dry cooling process and the dependable Superbelt® conveying technology. The use of the dry bottom ash handling system results in significant water and O&M cost savings. Since no water is used for ash cooling and conveying, pumps, piping, and water treatment systems are no longer necessary, and the associated costs are eliminated.
