The purpose of this study is to develop the superheated steam generator using the tubular flame. The tubular flame is formed in a rotating flow field by injecting the air-fuel mixture tangentially into the cylindrical chamber. The superheated steam generator consists of the cylindrical combustion chamber, internally finned tube as the evaporator, and the water tube as the super heater. The prototype of superheated steam generator was made. The thermal efficiency is 87.5% based on LHV at the hot-water supply mode. Subsequently, boiling experiment was carried out. The superheated steam generator could evaporate water in 100cc/min.
