Title:
STEAM HEATER
Document Type and Number:
Japanese Patent JP3394929
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a steam heater which prevents the temperature fluctuation of a heating section and prevents the occurrence of heating unevenness in an object to be heated.
SOLUTION: A steam ejector 6 is arranged at a pipeline 8 from which a steam supply pipe 3 is branched. A suction chamber 7 of the steam ejector 6 is connected to an air exit 21 of a condensate recovering device 16. The inlet side of the steam ejector 6 is provided with a control valve 10. The control valve 10 is connected to a temperature sensor 11 mounted in a jacket section 2. The opening and closing of the control valve 10 are controlled by the temperature sensor 11, by which the suction force of the steam ejector 6 is controlled and the steam temperature in the jacket section 2 may be controlled with good accuracy. The heating unevenness of the object to be heated may thus be prevented.
