Can the heat energy generated by the condensation of water vapor in the heat exchanger be compensated for using air?
Thread Content
In the heat exchanger, the inlet fluid is steam, and phase change occurs there; the outlet fluid is liquid with significantly reduced pressure. Some users have suggested that air can be used to restore the pressure. Everyone, share your opinions – this issue is really important!
It should be fine, right?~~~~~
Even if condensation occurs, the steam itself will automatically maintain the pressure, right?
Steam condensation equipment requires strict airtightness to maintain the heat exchange capacity specified in its design! For large-scale steam condensation equipment, vacuum pumping systems must also be installed to promptly remove any leaked or accumulated air, thereby ensuring that no other gases remain inside. Why! ? Because the presence of other non-condensable gases significantly reduces the heat transfer efficiency of steam condensation! So, if your heat exchange capacity has a very, very large margin! Other non-condensable gases can be introduced; you can give it a try. Another point is that when air is introduced, oxygen can cause severe corrosion in iron-based metal equipment.
I’ve never heard of using air to maintain pressure; what you said about breath makes sense
