Abstract

Pangkalan Susu Coal Fire Steam Power Plants (CFSPP) are planned to build in Tanjung Pasir Village, Langkat Regency taking sea water as cooling condenser of power plants, and through it back into the sea. To explore the possibilities of re-entry of the circulation of hot water to the intake, it is necessary to study the termal dispersion within the framework of those plans. In this study, numerical modeling to determine termal distribution pattern that comes out from CFSPP outlet. From the study it could be concluded that with the given intake inlet – discharge outfall design configuration and under the worst scenario, cooling water system of Pangkalan Susu unit 3 & 4 is safe i.e. re-circulation of warmcooling water will not happen. The Pangkalan Susu unit 3 & 4 will consume intact sea water (30.5oC). However, the Pangkalan Susu unit 1 & 2 will be influenced by the warm cooling system that may decrease its cooling system efficiency since its inlet is covered by shattered sea water (31.2oC – 32.2oC).keywords : thermal dispersion, power plant. numerical modeling

Abstract

The importance of exergy analysis in preliminary design of geothermal power has been proven. An exergy analysis was carried out and the locations and quantities of exergy losses, wastes and destructions in the different processes of the plan were pinpointed. The obtained results show that the total exergy available from production wells KMJ 68 was calculated to be 6967.55 kW. The total exergy received from wells which is connected during the analysis and enter into the separator was found to be 6337.91 kW in which 5808.8 kW is contained in the steam phase. The overall exergy efficiency for the power plant is 43.06% and the overall energy efficiency is 13.05 %, in both cases with respect to the exergy from the connected wells. The parts of the system with largest exergy destruction are the condenser, the turbine, and the disposed waste brinekeywords: exergy, irreversibility, geothermal power plant, KMJ 68
