Vapor blowing from the air ejector condenser...

🔍 Key Concepts

• condensation process in a surface condenser and what happens if steam is not fully condensed • relationship between condensate flow rate, temperature, and the ability to absorb latent heat from steam • how changes in pump speed or makeup feed would practically affect condenser vacuum and venting

💭 Think About

• Which condition would make it harder for the condenser to remove the latent heat of vaporization from the steam, so that some steam leaves as visible vapor at the vent? • Think about whether ‘more water’ or ‘colder water’ in the condenser would increase or decrease the chance of visible vapor at the vent. • For each option, ask: does this make condensation more complete, or less complete?

✅ Before You Answer

• Verify which option would reduce effective heat transfer in the condenser, leading to steam not fully condensing. • Check which options would improve condenser performance and thus are unlikely to cause vapor at the vent. • Consider normal troubleshooting practice: when you see vapor at an air ejector vent, what primary condition in the condenser are you most suspicious of?

Vapor blowing from the air ejector condenser vent may be caused by __________.

insufficient condensate flow

excessive condensate pump speed
