High-temperature air combustion technology is applied to produce surplus electric power and reduce dioxins, NOx and CO in combustion process of a stoker-type MSW (Municipal Solid Waste) incinerator. The macro-patterns of flow and combustion are analyzed numerically with an approximate combustion analysis code using physical model. Present simulation data, general distributions of the temperature, the velocity, and the chemical species, were approximately related to the experimental data measured using a simulated MSW incinerator. We found that blowing mixed gas of high-temperature air and exhaust gas to combustion beginning space was effective for the decrease of air for waste combustion.
