PROBLEM TO BE SOLVED: To obtain a reduced pressure steam heating apparatus which can optionally control the temperature of liquid in a tank only by supplying a small amount of a cooling fluid.SOLUTION: A steam supply pipe 3 is connected to a jacket part 11 of a reaction vessel 1. A suction means 2 is connected to a lower part of the jacket part 11. The suction means 2 is constituted of an ejector 14, a tank 5, and a circulating pump 15. A circulating liquid exhaust nozzle 27 spouting circulating liquid in the shape of a shower is arranged in an upper part of the tank 5. A heat pipe 28 having a heat sink and a radiator is attached to the circulating liquid exhaust nozzle 27. While the circulating liquid is spouted in the shape of a shower from the circulating liquid exhaust nozzle 27, a part of heat quantity reserved in the circulating liquid is released to the air so that the liquid temperature of the circulating liquid can be decreased. |
