PROBLEM TO BE SOLVED: To easily obtain high-temperature steam while preventing the reduction in operation efficiency and breakage of a boiler by minimizing the generation of scales by direct heating of water. SOLUTION: This instantaneous steam producing device comprises a steam generating means and a gas discharge cylinder 7 of a back fire using aerobic heat evaporation re-combustion type burner A (Patent No. 2838241). In the steam generating means, an aqueous solution injection port 33 is provided in one or several proper positions of a cylindrical steam generating cylinder 30 having a discharge cylinder 34 at one side and a mounting plate 35 at the other side with an insert port 32a, and an aqueous solution feeder J is connected to an aqueous solution feeding pipe 36 provided in the injection port 33 through an aqueous solution feed pipe 37. The burner A is inserted to the insert port 32a, whereby the burner A is continuously provided with the steam generating means. COPYRIGHT: (C)2005,JPO&NCIPI
