The purpose of this study is R & D of micro superheated-steam generator having 90cc/min evaporation rate at 250℃ superheated steam. The micro steam generator should be within 200×200×150mm including the burner, the micro boiler and the combustion chamber to be equipped into the household cooking stove. Therefore, the air-preheating and the gas re-circulation are applied to the micro steam generator to achieve complete combustion in limited space. Thus were achieved downsizing of combustor, low-NO_x combustion with high efficiency.
