Seeking advice on the design of a vapor-deficient condenser
Thread Content
This post was last edited by B0SS on 2017-12-1 at 17:41. I have a question: our plant is equipped with a 6000KW extraction-type steam turbine generator set. The inlet temperature is 450 degrees, with a pressure of 3.43 MPa; the outlet temperature is 40–45 degrees, and the pressure is 7–10 KPa. Originally, it was fitted with a copper tube condenser (using circulating water for cooling), and the temperature of the waste steam condensate was 40–50 degrees. Due to insufficient circulating water volume, it has been decided to stop using the condenser and instead install a new waste steam condenser; the conditions for the outlet water will remain unchanged. I would appreciate your advice on what size waste steam condenser should be used. Thank you!
Stay positive, don’t get down; looking forward to experts’ answers:P
You need to provide the temperature and flow rate of the circulating water so that calculations can be performed
No circulating water is required; evaporation cooling is used separately. The location is Hebei, and the wet-bulb temperature can be set at 28
The exhaust temperature is 40-45 degrees; to what temperature do you want to condense it? “Due to insufficient circulating water volume, it has been decided to stop using the condenser and instead install a new waste steam condenser. Does a waste steam condenser require circulating water as well?
Was the air-cooled ACC changed?
“Use evaporation cooling separately” — What medium is to be evaporated? R22？
