Abstract
In this study, we have the flow between counter-flow nozzles clarified by the fluid analysis and combustion experiments. The high-temperature steam as heated flow was supplied from the lower nozzle with O_2. The fuel was supplied from the upper nozzle. In particular, we focused on the lateral flow rate, the temperature distribution of the impinging fluids and varied ratios of fuel and nozzle distance. The result showed that the range that can be combusted stably was changed by differences in equivalence ratio and also variation of the nozzle distance influence flame structure.
