The temperature of flue gas from the incinerator is lowered by a waste heat boiler, economizer, and cooling tower. Fly ash, hydrogen chlorides, sulfuroxides, and dioxins are removed by the filter-type dust collector, while nitrogen oxides are removed by the denitrification tower. Having been rendered harmless, the flue gas is then released into the evironment via the stack.
