Title:
HEAT EXCHANGER
Document Type and Number:
Japanese Patent JP2007285574
Kind Code:
A
Abstract:

To provide a heat exchanger capable of keeping a surface temperature of a heat exchange container in a maximum temperature state.

The plurality of heat exchange containers 1 are connected to a steam supply pipe 2 through a steam ejector 5. A steam trap 4 is mounted at a downstream side of the heat exchange container 1 through a condensate discharge pipe 3 and a gas-liquid separation tank 10. A lower end portion of a branch pipe 7 is connected to an upper portion of the gas-liquid separation tank 10, and an upper end portion of the branch pipe 7 is connected to a suction chamber 6 of the steam ejector 5. The steam and the condensate in the heat exchange container 1 flow down to the gas-liquid separation tank 10 from the condensate discharge pipe 3, and the steam is sucked to the steam ejector 5, thus the steam in the heat exchange container 1 is forcibly convected/circulated, and the surface temperature of the heat exchange container 1 can be kept in the maximum temperature state.
