摘要

The present research is related to the development of a hybrid system, which is composed of solid oxide fuel cell (SOFC) and micro gas turbine (MGT) assisted with recuperator. The main problems in small-size com-bustors for MGT are related to mixing enhancement and flame stability because the Reynolds number is very low. To solve these problems, we developed a multi-jet type baffle plate for the combustor. The reacting flow fields in this device were investigated by using flow visualizations and blow-out experiments. As expected this kind of baffle plates enhance the turbulence mixing in the low Reynolds number flows and maintain the flame stability in the small cornbustor.
