| Research Abstract |
In this study, we had developed a new safe small hydrogen combustor, called the cyclone jet combustor, which consists of a jet diffusion flame stabilized by a swirl pilot flame. Hydrogen flames are safely stabilized by the cyclone jet combustor over the blowout condition of jet flame. There exists the minimum temperature region between the jet flame and the middle flame, which affects the flame stabilization. The removal of the minimum temperature region is essential for the expansion of the stable condition. Thus, the annular air jet nozzle was replaced with a multi-port air nozzle. Thereby, the minimum temperature region was completely removed to expand the stable condition extremely.
