We recently completed the design of a custom steam-to-water shell and tube heat exchanger tailored for a customer’s process heating application. The equipment is engineered to ensure reliable heat transfer, long service life, and excellent performance under continuous operation.
Process Requirements
Hot Side (Steam – Shell Side)
Medium: Saturated Steam
Inlet Temperature: 133.7°C
Outlet Temperature: 133°C
The steam condenses on the shell side, releasing latent heat to warm the process water on the tube side.
Cold Side (Water – Tube Side)
Medium: Water
Inlet Temperature: 70°C
Outlet Temperature: 80°C
The high water flow ensures stable heat pickup with low temperature approach
Mechanical Design & Construction Materials
Type: Shell & Tube Heat Exchanger
Configuration: Steam on shell side, water in tubes
Tube Type: Plain tubes
Stainless steel 304 is selected due to:
Excellent corrosion resistance to condensate
Good thermal conductivity
Long service life in steam heating applications
Hygienic and suitable for food, chemical, and industrial processes
Performance Considerations
The design ensures:
High condensation efficiency due to saturated steam on the shell side
Low pressure drop for both steam and water
Optimized tube pitch and layout for maximum heat transfer
Proper steam condensate drainage to prevent flooding
Easy maintenance through removable channel covers
Special attention was given to shell-side steam distribution and condensate removal to maintain consistent heat duty and stable operating temperatures.
Application Areas
This heat exchanger is suitable for:
Food and beverage heating
Chemical processing
Pharmaceutical hot water generation
Laundry and sterilization systems
Factory process heating
District heating systems
Conclusion
This custom steam-to-water shell & tube heat exchanger is engineered to deliver 1,406 kW of reliable heat transfer using robust SS304 materials and proven industrial design standards. With one unit fully designed to meet the customer’s operating conditions, it provides long-term, efficient, and corrosion-resistant performance for demanding process heating duties.
