Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of waste heat recovery, and particularly relates to a new fountain type waste heat boiler structure. BACKGROUND

[0002] A waste heat boiler is a device that produces steam from waste heat recovered in a hot stream. A common boiler design is a shell-and-tube heat exchanger with a bank of heat exchange tubes arranged inside a cylindrical shell. The heat exchange tubes are designed as U-tubes, and the boiler is designed as an overall upflowing and downflowing structure.

[0003] The waste heat boiler structure in the prior art has the following problems: during the heat exchange process, a large amount of heat is released from the tube-side medium (such as high-temperature gas or fluid) to the shell-side medium (such as water or coolant), and the temperature difference will cause significant thermal stress on the heat exchange tubes. When one side of the heat exchange tube is subjected to the impact of high-temperature gas and the other side is in contact with water or other cooling medium, the temperature difference stress is particularly prominent. The alternating stress generated in the heat exchange tube by the temperature difference stress will accelerate the fatigue process of the material. Under the long-term action of the alternating stress, the heat exchange tube may be damaged, such as cracking and breaking, thereby shortening its service life and causing internal leakage, and the actual use effect is not good.
