Condenser temperature
Condenser temperature
(OP)
I an looking at a conceptual design for a new energy recovery system and want to use the water coming off of a coal fired electric generating plant turbine steam condenser. Can anyone tell me a typical temperature or range of temperatures that one would find in the water coming off such a condensate condenser?
Thanks
Thanks

RE: Condenser temperature
If there was energy in the turbine condensate that was worth recovery, it would have been recovered -- in the turbine.
The temperature of typical condensing steam turbines is in the range of saturated temperature corresponding to 0.75 psia - 2.0 psia (i.e. 90F - 125F). As KiwiBob has pointed out, this is saturated steam, typically 10 - 20%moisture at the exhaust.
Please at least consider that somebody has looked into this before you.
Good luck.
RE: Condenser temperature
Let us say the maximum ambient pressure of a region is 50 deg C.
Then the theoretical minimum condenser pressure is saturation pressure is 0.1235 bar. But in actual practice a temperature approx 20 deg is added to the maximum ambient temperaure.
Therefore condenser pressure = 0.3119 bar ( Corresponding to the 50deg+20deg saturation pressure).
Now Maximum condenser outlet water temperature is 70 deg.
Depending on the location of your power plant you can find the condenser water outlet temp. But keep it in mind that if you want to use that water for energy recovery only a small delta T (in this case 20 deg) only available for recovery.
