抄録: Dioxins in the combustion gas of Municipal Solid Waste Incinerator(MSWI) are resynthesized during passing through the lower temperature region between the outlet exhaust boiler and the outlet gas duct. As a countermeasure , a spray water injection method is effective which prevents dioxins from resynthesizing by rapidly cooling down the gas temperature less than the temperature required for resynthesizing of dioxins. Using the evaporation rate of a water droplet calculated by Mizutani’s evaporation theory and the dioxins formation rate estimated by the theory of Altwicker and Stanmore, we have developed Excel program for predicting the combustion gas cooling rate and dioxins formation rate. A dioxins suppression factor was found to be dependent on the spray water droplet diameter. Therefore, some simulations have been done using real incinerator data. As a result, gas cooling rate, dioxins formation rate and dioxins product quantity can be estimated. If incinerator waste material element analysis will be available, the Excel program will be able to estimate the incinerator dioxins product quantity easily.
