Abstract :
Incineration of persistent organic pollutants (POPs) is an important alternative way for disposal of this type of
hazardous waste. PCBs are very stable compounds and do not decompose readily. Individuals can be exposed to
PCBs through several ways and damaged by their effects. A well design of a waste incinerator will convert these
components to unharmfull materials. In this paper we have studied the design parameters of an incinerator with
numerical approaches. The CFD software Fluent 6.3 is used for modelling of an incinerator. The effects of several
baffles inside the incinerator on flow distribution and heat is investigated. The results show that baffles can reduce
eddy flows, increase retaining times, and efficiencies. The baffles reduced cool areas and increased efficiencies of
heat as maximum temperature in two and three baffle embedded incinerator were 100 and 200 °C higher than the
non-baffle case, respectively. Also the gas emission leaves the incinerator with a lower speed across a longer path
and the turbulent flow in the incinerator is stronger.
