JFE Engineering has developed the advanced stoker-type incineration system "JFE Hyper 21 Stoker System", which realizes low excess air combustion, minimization of environmental pollution and more effective use of energy by applying High-temperature Air Combustion Technology (HiCOT). To improve the performance of this system, we have attempted to develop the numerical simulator to grasp the combustion behavior in the incinerator. For the first step, we calculated by using the HiCOT zone Model with the suitable reaction mechanism and it was confirmed that our numerical simulator is appropriate for an analysis of the combustion behavior. In this paper, for the next step, we calculated by using the Entire Incinerator Model and compared calculated values and measured values in actual plant. As a result, it was showed that our numerical simulator is useful for a design tool.
