CFD modeling of incinerator to increase PCBs removal from outlet gas

Incineration of persistent organic pollutants (pops) is an important alternative way for disposal of this type ofhazardous waste. pcbs are very stable compounds and do not decompose readily. individuals can be exposed topcbs through several ways and damaged by their effects. a well design of a waste incinerator will convert thesecomponents to unharmfull materials. in this paper we have studied the design parameters of an incinerator withnumerical approaches. the cfd software fluent 6.3 is used for modelling of an incinerator. the effects of severalbaffles inside the incinerator on flow distribution and heat is investigated. the results show that baffles can reduceeddy flows, increase retaining times, and efficiencies. the baffles reduced cool areas and increased efficiencies ofheat as maximum temperature in two and three baffle embedded incinerator were 100 and 200 °c higher than thenon-baffle case, respectively. also the gas emission leaves the incinerator with a lower speed across a longer pathand the turbulent flow in the incinerator is stronger.
