Glass-Lined Heat Exchangers

Application and Function
Glass-lined heat exchangers are commonly used for phase change of corrosive vapors into liquid form (condensers) and for temperature adjustment of corrosive fluids.

Design Types
Depending on the application, glass-lined heat exchangers are manufactured in various configurations, including shell and tube, shell-in-shell, plate type, and jacketed pipe designs.

Thermal Design Considerations
In the design and capacity calculation of glass-lined heat exchangers, the additional 2 mm thickness of the glass lining and its impact on heat transfer must be considered. Under identical process conditions, compared to stainless steel heat exchangers, glass-lined heat exchangers require a larger heat transfer surface area to compensate for reduced heat transfer.

Performance Characteristics
Due to the microscopic bonding between the glass lining and the steel substrate, the combined glass–metal structure provides significantly higher efficiency compared to other coating systems.
