Numerical Simulation for the Improvement of Complex Incinerator

신개념 소각 연소실의 성능향상을 위한 해석연구 사례

Using the CFD method, we investigated the combustion characteristics of grate-rotary kiln incinerator through the residence time, path line of flow and distributions of temperature and CO mass fraction according to the shape of mixing chamber and the existence and nonexistence of baffle at the exit of bypass duct. The results show that the now mixing and residence time could be variable according to the shape of mixing chamber and baffle, and we could know the temperature in the mixing chamber could increase too high if the combustion process on the grate retarded.
