Design formats for heat exchangers with scaling-prone substances
Thread Content
For the high-pressure ash water heaters used in coal water slurry gasification, high-pressure ash water tends to form scale; the pressure is 7.8 Mpa. How should the appropriate model be selected during the design of the heat exchanger in order to reduce scaling in the water system? I hope everyone can offer valuable suggestions.
I’m also very concerned about this issue and hope that experts can provide answers. Increase the flow rate? Should it be made as a U-shaped tube or a floating head type for the shell side?
It can be designed as a fixed tube sheet or U-type heat exchanger, with high-pressure gray water flowing through the tube side.
High-pressure water can be used, or a corrosion inhibitor can be added; if corrosion and scaling are severe, the tube bundle can simply be replaced.
The approach is different from the conventional one; it doesn’t seem to stem from traditional craftsmanship?
Yes, I am involved in equipment design and manufacturing. My major is process engineering.
U-tube heat exchanger, high-pressure cleaning > replace tube bundle. Sis Gn, you’re amazing – to think of that!
Since the material itself makes it impossible to eliminate this issue through design, it is recommended to add auxiliary equipment online to solve the problem once and for all
A floating-head heat exchanger is required for the tube side.
The floating head type is used to remove the varnish from the shell side. . .
