1. Overview
A kettle reboiler is a heat exchanger with the characteristics of a floating head and U-tube heat exchanger. The size of an evaporation space set on the upper part of the shell is determined by the gas production and the required steam quality. The tube bundle of this heat exchanger can be a floating head, U-tube and fixed tube sheet structure, so it has the characteristics of a floating head and U-tube heat exchanger.

3. Structure
The difference in structure from other heat exchangers is that an evaporation space is set on the upper part of the shell, and the size of the evaporation space is determined by the gas production and the required steam quality. The evaporation space is large for those with large gas production and high steam quality requirements, otherwise it can be smaller.
4. Advantages
Like floating head and U-tube heat exchangers, this type of heat exchanger is easy to clean and maintain, can handle unclean and easy-to-scale media, and can withstand high temperature and high pressure.
5. Application fields
Kettle reboilers are widely used in chemical, petrochemical, food, pharmaceutical, environmental protection and other industries. They are mainly used to heat liquids, evaporate solvents or water, recover energy and promote the separation of substances. Its core function is to generate steam or gas by heating liquids, thereby supporting other subsequent industrial processes.
