PROBLEM TO BE SOLVED: To obtain steam-heating equipment which can heat an object to be heated with steam of about 100 deg.C in temperature with accurate temperature, without being affected adversely by the air. SOLUTION: The steam-heating equipment is constituted, in such a way that a steam supply pipe 35 for supplying steam is connected to the jacket section 4 of a reaction furnace 3. Then a condensate recovery device 1 is connected to the lower part of the jacket section 4. In addition, the high pressure- operated fluid introducing port 9 of the device 1 is branched, and an ejector 11 is connected to one branched port 19. Moreover, the suction chamber 14 of the ejector 11 is connected to the jacket section 4 via a pipeline 37 and a thermally operated valve 43. Whenever high-voltage steam is supplied to the ejector 11, a suction force is generated in the suction chamber 14 of the ejector 11, and the air in the jacket section 4 is sucked into the ejector 11 and is discharged to the outside.
