PLTP Kamojang is one of power plants in Indonesia that utilizes geothermal energy. PLTP Kamojang consists of 3 units with a generated power is 30 MW for Unit 1 and each of 55 MW for Unit 2 and 3. To optimize the geothermal energy, then we do redesign the system used. <br /> <br /> <br /> To increase the power generated, then designed a system that can lower the condenser pressure. Condenser pressure of 0.1 bar absolute initially decreased to 0.079 bar absolute. To achieve these conditions is done by adding the <br /> <br /> <br /> rate of cooling water to condense the steam. The rate of cooling water required is 3200 kg/s, which is channeled through two parallel pipes. In addition, the gas extraction system is also designed to support the changes of condenser pressure. <br /> <br /> <br /> In the wet bulb temperature environments ranging from 12oC -29oC has done an analysis of the power generated by the system. The result shows that with this system redesign, the generators power of PLTP Kamojang Unit 2 can be increased up to 1.25 MW. In addition, the gas extraction system is also simulated. <br /> <br /> <br /> Gas extraction system is used to attract the non-condensable gases from the condenser so that the condenser pressure is not increased. The results showed that the gas extraction system designed can be used to attract the non-condensable gas.
