JFE Engineering has developed the advanced stoker-type incineration system "JFE Hyper 21 Stoker System". It is equipped with some new technologies to meet requirement to a municipal solid waste incineration system. Main technology of this system is High-temperature Air Combustion Technology (HiCOT), which realizes low excess air combustion. This paper describes the numerical simulation of combustion behavior in JFE Hyper 21 Stoker System. Firstly, a few kinds of kinetic mechanisms of combustion reaction were examined to select suitable one for a large-scaled numerical simulation of HiCOT. After we selected Yetter mechanism, two kinds of three-dimensional models, HiCOT zone model and entire incinerator model, were made and numerical simulation was performed by using these models. In this paper, we show the effectivity of these models that clarify the combustion behavior in JFE Hyper 21 Stoker System using HiCOT.
