Abstract

Tujuan penelitian ini adalah untuk menganalisis perpindahan panas dan efektivitas Gas Turbine Closed Coooling Water Heat Exchanger pada jam 08.00 pagi-16.00 sore karena adanya pengaruh dari udara ambient. Pengambilan data dengan metode observasi di PT. PLN (PERSERO) Sektor Pembangkitan PLTGU Cilegon. Untuk mengetahui perpindahan panas dan efektivitas Gas Turbine Closed Coooling Water Heat Exchanger digunakan metode perhitungan NTU dilengkapi dengan metode LMTD. Hasil perhitungan tertinggi perpindahan panas pada Gas Turbine Closed Coooling Water Heat Exchanger adalah 2914486,227 W dan yang terendah adalah 2582780,941 W. NTU Gas Turbine Closed Coooling Water Heat Exchanger adalah 0,77 dan yang terendah adalah 0,52. Efektivitas Gas Turbine Closed Coooling Water Heat Exchanger tertinggi   adalah   43,13 %   dan   yang   terendah adalah 34,2 %
 
Kata Kunci :temperatur, perpindahan panas, efektivitas
