Analisis Perpindahan Panas (Heat Transfer) Kondensor pada Unit 4 PLTU PT PLN (Persero) Unit Pelaksana Pembangkitan Belawan

Abstract

Electricity needs in Indonesia are vital for the people of Indonesia, especially in this globalization era. Indonesia is implementing an accelerated electricity generation program of 10,000 MW by establishing several power plants, especially power plants using steam power (PLTU). The purpose of this Final Project Research is to conduct a Heat Transfer Analysis on the Condenser in PT PLN (Persero) Belawan Generation Implementation Unit. Condenser is one type of heat exchanger that functions to condense used steam from turbines, which is sea water. The type of condenser used at PT PLN (Persero) Belawan's Generation Unit is a surface condenser. The results obtained from this thesis are the value of the heat transfer rate and the effectiveness (ε) of unit IV condenser from 13 May 2019 to 15 May 2019. the heat transfer rate is 126 MW. While the effectiveness (ε), obtained 0.2524%. And the Vacuum Pressure is obtained 0.1492 Bar This shows that the condition of the condenser is still quite good, because steam can go to the condenser, so that the rate of heat transfer and the effectiveness of the condenser is able to condense steam into liquid.
