container for burning refuse, or plant designed for large-scale refuse combustion. In the second sense, an incinerator consists of a furnace into which the refuse is charged and ignited (usually by a gas burner), a secondary chamber in which burning at a high temperature is continued to complete the combustion process, and flues to convey the gases to a chimney. Auxiliary equipment may include steam boilers for using waste heat to generate electricity or to heat nearby buildings and devices for removing ash and other pollutants from the flue gases.
