Gas Turbine & Psychrometric chart

Click For Summary
SUMMARY

The discussion centers on understanding the Psychrometric chart and its implications for gas turbine operation, particularly regarding air quality and moisture management. Participants emphasize that an increase in air pressure can lead to condensation of water vapor, which poses risks such as compressor corrosion. Key resources mentioned include articles on gas turbine testing and guides on reading the Psychrometric chart. The conversation highlights the importance of comprehending dew point, humidity, and pressure effects in relation to gas turbine performance.

PREREQUISITES
  • Understanding of Psychrometric charts
  • Knowledge of gas turbine operation
  • Familiarity with concepts of dew point and humidity
  • Basic principles of thermodynamics related to air pressure
NEXT STEPS
  • Study the Psychrometric chart in detail using resources like "How to Read and Use a Psychrometric Chart"
  • Research the effects of humidity on gas turbine performance
  • Explore the relationship between air pressure and condensation in gas turbines
  • Review rigorous engine integrity tests conducted on modern gas turbines
USEFUL FOR

Engineers, gas turbine operators, and anyone involved in the design and maintenance of gas turbines who needs to understand the impact of air quality and moisture on engine performance.

Hi Everyone,
So I seem to have many problems understanding the Psychrometric chart and its physical meaning. First of all, I would be so thankful if you could introduce me a source which can be useful to physically and fundamentally understand the dew point, effect of pressure, humidity... and better to say Psychrometric chart.

Actually I was reading some articles about gas turbine, and I have started to think about the air input, its quality, and the risk of moisture and consequently corrosion. There should be a risk of water drops in compressor if the vapor in inlet air condenses... It is here where my problem with psychometry starts... so if the compressor increases the pressure of air, it means that the probability of condensation increases or decreases?

I hope you can help me understand the fundamental of psychometry, I feel embarrassed not to understand it well :)

Modern engines can ingest huge amounts of rain without too many problems .

The engine integrity tests carried out are very rigorous and include rain , hail , cowling ice , frozen chickens and deliberately broken fan blades .

Check out this site for learning about the Psychrometric Chart. Yes an increase in pressure can cause water vapor to condense.

Edit: Here's the link http://www.powerknot.com/how-to-read-and-use-a-psychrometric-chart.html
I failed at embedding it.

Which site is that? There's no link apparent.
 
Regarding water vapour formation and condensation - anyone remember the cloud chamber experiments from school days ?
 
Thnaks everyone!
