Waste to Energy Plant Diagram
Waste-to-energy plants generate electricity by burning municipal wastes in large furnaces to produce steam, which in turn drives a steam turbine to generate electricity. Mass burn facilities use solid waste directly off garbage trucks, without shredding or processing the materials. The solid waste stored temporarily in a large bunker, picked up by a claw lift and deposited in the furnace. The firing produces steam, which turns a steam turbine to generate electricity. Flue gases are scrubbed to remove nitrogen oxide, mercury, dioxin, acid gases and particulate matter, then are exhausted through a chimney. Ashes are removed via conveyor to trucks which take them to the landfill for disposal or use as a day cover.
