Abstract :
If there is a change in steam that enters the condenser caused by a changed operating pattern, it can be ascertained that it will cause an influence on the heat transfer flow rate in the condenser, the condenser is a device that functions to utilize the ex-turbine steam by cooling it and then the water from the condensation is pumped back to HRSG. The calculated parameters are sea water inlet temperature, sea water outlet temperature, condensate water temperature and steam temperature entering the condenser. in the 2-2-1 operation pattern using 2 gas turbines, 2 HRSG, and 1 steam turbine with a power output of 110 MW, while in the 3-3-1 pattern using 3 gas turbines 3 HRSG and 1 steam turbine with power the resulting 167 MW using the LMTD (log mean Temperature difference) method.
