Abstract

Abstract

Incineration is an effective way for solid waste treatment， with grate incinerators being the most widely used equipment. As a tool， CFD is widely used in the waste incinerator design and optimization， the typical model is coupled by FLIC and FLUENT. However， it cannot fully consider the combustion process and can only be coupled manually， which results in significant errors. This study developed an optimized bed model and compared ot with the FLIC model.In addition， the calculation results from the two models were compared and analyzed. Furthermore， CFD simulations were performed for a 900 t/d incinerator using the optimized bed model coupled with STAR CCM via an automatic coupling method. Finally， the optimization algorithm of SHERPA was used to optimize the air distribution of the incinerator. The optimization results showed that the thermal burn-off rate decreased from 3.1% to 0.25%， and the fuel combustion became more complete； the residence time of flue gas above 850℃ in the furnace increased from 4.22 s to 4.55 s， which was more conducive to the removal of dioxins. Overall， the simulation calculation achieved ideal optimization effects and provide an improved CFD method for waste incinerator design.
