Abstract
Recently, environmental pollution caused by emission of toxic substances from waste incineration flue gas has been become a social problem. For removal of toxic substances as polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans, Bag filter systems are used in many cases. This system, however, needs waste gas quenching apparatus to remove toxic substances efficiently and for its protection. So far, two-fluid nozzle was used for quenching [cooling] frequently and it needs compressor to atomize water. We developed air assisted pressure nozzle as energy saving two-fluid nozzle for waste gas quenching [cooling]. This nozzle can atomize water in low power compared with two-fluid nozzle. In this paper, we report the characteristics of air assisted pressure nozzle and installation case in actual waste incinerator plant.
