This post was last edited by ai444099439 on 2011-4-23 20:26. When using steam for heating, for example, heating steam at 1.2 Mpa to 550 degrees, will the steam pressure increase? If it doesn’t rise, can it still be heated to such a high temperature? Is there steam available at 0.2 Mpa and 550 degrees? What type of steam is this?
Learning*, experts, please reply quickly! !
It depends on the heating conditions you choose; if heating at constant volume, then the pressure will definitely increase. If it is heating at constant pressure, then the pressure will not rise. It can be heated to 1.2 MPa and 550°C; this is superheated steam with a very high degree of superheating
You can calculate this using the gas law; for a gas of the same volume, the pressure will definitely increase when heated. What you’re describing must be superheated steam, as such a state does not exist in practical applications
Theoretically, what you say is possible, but in actual production, no one would heat steam to such an extreme temperature, as it represents a waste of energy! As for the first question you mentioned, I think what was said on the 3rd floor makes sense~
Thank you. In fact, we need steam at 0.2 Mpa and 550 degrees
It seems impossible to do it! Low-pressure high-temperature steam – I’ve heard of it for the first time.
Although it’s not common, such cases do exist; I’ve seen them a few times. It’s steam used for long-distance heating, supplied by thermal power plants. Due to the long distances involved, sometimes exceeding ten kilometers, high superheat levels are required for this steam. . This post should be posted in the boiler forum, where there are many experts.
