Ash Generated from the MSW Combustion Process. The rest of the MSW combustion ash is called bottom ash (8090 percent by weight). The main chemical components of bottom ash are silica (sand and quartz), calcium, iron oxide, and aluminum oxide. Bottom ash usually has a moisture content of 2262 percent by dry weight.

Reducing Bottom Ash Dewatering System Maintenance. Many coalfired power plants use water to cool and sluice bottom ash away from the bottom of the boiler for final disposal, and then they recirculate the water for reuse. This system is also known as a hydraulic bottom ash system. Many plants dispose of the ashladen water to an ash containment pond,...
