Waste incineration is one of many societal applications of combustion. As illustrated in Figure 3-1, the typical waste-incineration facility includes the following operations:
Waste storage and feed preparation.
Combustion in a furnace, producing hot gases and a bottom ash residue for disposal.
Gas temperature reduction, frequently involving heat recovery via steam generation.
Treatment of the cooled gas to remove air pollutants, and disposal of residuals from this treatment process.
