Abstract

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 temperature accuracy, without being adversely effected by the air. SOLUTION: The steam-heating equipment is constituted, in such a way that a steam supply pipe 3 for supplying steam is connected to the jacket section 2 of a reaction furnace 1. Then the pipe 3 is branched, and a steam ejector 5 is connected to the branched pipe. In addition, the suction chamber 13 of the ejector 5 is connected to the jacket section 2 via a thermally operated valve 12 and the actuator section 18 of the valve 12 is made to communicate with a temperature-sensitive pipe 17. When air is filled in the jacket section 2 and the temperature of the section 2 drops, the pipe 17 detects the temperature drop and opens the valve 12. Consequently, the air is sucked into the steam ejector 5 and discharged to the outside.
