SUMMARY

The discussion centers on the efficiency of steam compressors designed to compress sub-atmospheric steam to atmospheric pressure and above. Participants report that the efficiencies of available steam compressors are often below 10%, raising concerns about their effectiveness for specific applications like vacuum evaporation. The conversation highlights a lack of understanding among manufacturers regarding low-pressure steam compression, suggesting that many may not provide accurate efficiency data. The need for reliable information on steam compressor efficiencies is critical for projects involving low-pressure steam systems.

PREREQUISITES
  • Understanding of steam compression principles
  • Familiarity with vacuum evaporation processes
  • Knowledge of compressor efficiency metrics
  • Basic technical knowledge of steam systems
NEXT STEPS
  • Research steam compressor efficiency calculations
  • Explore specific models of steam compressors for low-pressure applications
  • Investigate vacuum evaporation technology and its requirements
  • Review industry standards for steam compressor performance
USEFUL FOR

Engineers, project managers, and technical professionals involved in steam system design, particularly those focused on low-pressure steam applications and efficiency optimization.

For some purpose, I need a steam compressor that can compress sub atmospheric level steam to atmospheric and above. I want to know what's the efficiency of an average steam compressor available in market. I have got some replies from a few steam compressor manufacturers, but the system they are offering have efficiency less than 10%. Do other steam compressors are inefficient to that level in reality?
 
Engineering news on Phys.org
Please tell us what this project is all about and what your level of technical knowledge is .
 
This is about vacuum evaporation of water in an Evaporator and discharge that steam to keep the pressure level inside same. I can't say no more than that at this time. I want to know what are the efficiencies of compressors used in such system.
 
Does that make this irrelevant?
 
Yes .
 
That's your own opinion.
 
Well, everything said in this page is about gas compression, steam compression is different. Actually, I am looking for the info for a project of my own. It's about compressing very low pressure steam upto atmospheric level and above. I have found just two quotes so far and the efficiency I have found is below 10%. Now, I am sure that they don't have any idea about low pressure steam compression and are making mistakes.
