Heat exchanger tube side and shell side
Thread Content
For heat exchange between steam and deionized water, should it take place in the tube side or the shell side? Why?
The steam can flow in the tube side; with a higher steam pressure, using the tube side allows for lower requirements regarding the material used in the shell side. However, under normal circumstances, when both the steam and demineralized water pressures are not very high, it doesn’t matter which one is used
I don’t know what quality of steam this is. Does steam undergo phase change? These affect the selection of the tube and shell sides
You want to heat the desalinated water, right? Steam can flow through the shell side, while deionized water flows through the tube side. A steam trap should be installed in the shell side to achieve a better heating effect.
Yes, the demineralized water is heated with steam, so why go through such a process?
Brine flows in the tube side, allowing the precipitated crystals to be easily cleaned； Steam flows through the shell side, while the liquid water is easily removed.
In heat exchangers, heat generally flows through the shell while cold flow passes through the tubes; that’s usually the case
To heat the deionized water, saturated steam is generally used; I think it’s better for the steam to flow through the shell side. 1. Steam flows through the shell side, facilitating the removal of condensate and non-condensable gases. 2. Steam flows through the shell side, reducing the temperature difference between the shell wall and the tube wall.
