Structural Design Improvement of High-pressure Gas Cooler
In response to the risks of excessive temperature difference stress on the tube shell side,reduced convective heat transfer coefficient of thick walled heat exchange tubes,and reduced reliability of welded joints in the fixed tube plate structure of high-pressure large-scale gas coolers,structure design improvements were made to the high-pressure gas cooler.The high-pressure cold side fluid was exchanged with the low-pressure hot side fluid,and the high-pressure cold side fluid was placed on the tube side.A rod baffle was used to support the U-shaped tube bundle structure,avoiding safety hazards caused by shell side expansion joints and enhancing the reliability of the connection of heat exchange tube and tube-sheet welded joints.By utilizing high-pressure heat exchange design technology,all design details is fully considered to ensure the safe operation of the equipment.
