Condenser Performance Monitoring
A.) Condenser Performance Monitoring:-
B.) Typical Condenser Calculations:-
* Expected BP to be derived from design BP after applying corrections for Load and CW inlet temperature during test
C.) Factors affecting Condenser Performance:-
-
Condensate Sub cooling
-
Air In-Leakage
-
Condensate dissolved Oxygen for air ingress
-
Condenser after cation conductivity for condenser tube leakage
-
hot well and Condensate Temperature
-
Circulating Water Flow
-
Circulating Water Temperature
-
6mm hg condenser vacuum detrition is eq to 1% IP/LP cap loss
-
CW flow that is CW velocity is related to condenser heat transfer
-
Checking for condenser cleanliness by videoscope is a good practice
-
Cleanliness of air suction zone tubes
-
Air steam mix temp depression more than 4.5 degree confirms air ingress
-
as a rule of thumb, each 5 degrees of condensate sub cooling results in a 0.05% increase in heat rate.
-
Abs pressure transmitters to be used for condenser Vacuum measurement.
