This study is the research and development of the tubeless boiler with hydrogen combustion. This boiler is structured by spraying water into the oxy-hydrogen diffusion combustion gas. Steam is produced by the reaction of the oxy-hydrogen combustion and the spray evaporation, thus, the water tubes used in the conventional boiler are not required to produce the superheated steam. Oxygen is diluted by the steam recirculation from the exhaust gas to suppress the combustion speed. This paper reports the development tubeless boiler of 5kW heat release rate with 80g/min steam generation with the intermitted spraying evaporation and by the Diesel jet nozzle.
