Abstract

High pressure heater adalah alat yang digunakan untuk memanaskan air umpan boiler dengan memanfaatkan uap ekstraksi High pressure turbin dan Intermediet pressure turbine. Performa High pressure heater sangat mempengaruhi efisiensi dari boiler. Performa High pressure heater ditentukan oleh DCA (Drain Cooler Approach), TTD (Terminal Termperature Difference), dan Overall Heat Transfer Coefficient (U). Tugas akhir ini bertujuan untuk menganalisa performa High pressure heater #1 di PLTU 1 Jawa Timur Pacitan. Alat utama dari pengambilan data ini adalah High pressure heater #1 yang berada di PLTU 1 Jawa Timur Pacitan. Pengambilan data dilakukan pada beban 200 MW pada bulan Oktober 2013 dan April 2014. Hasil analisa data pada beban 200 MW di bulan Oktober 2013 diketahui bahwa nilai TTD - 6,334 °C, DCA 1,839 °C, U 2399,97 kj/h. m². °C. Hasil analisa data pada beban 200 MW di bulan April 2014 diketahui bahwa nilai TTD - 4,902 °C, DCA 1,979 °C, U 2096,5 kj/h. m². °C. High pressure heater #1 Pada beban 200 MW kondisi TTD selisihnya 1,432 °C, DCA selisihnya 0,14 °C, U selisihnya 303,47 kj/h. m². °C. dari perhitungan dapat diketahui bahwa High pressure heater #1 PLTU 1 Jawa Timur Pacitan masih bekerja kurang baik dan mengalami penurunan performa. Kata kunci : High pressure heater, High pressure heater, High pressure heater, Drain Cooler Approach, Terminal Termperature Difference, dan Overall Heat Transfer Coefficient. High pressure heater is device use to heat the boiler feed water by utilizing extraction steam of High pressure turbine and Intermediet pressure turbine.. High pressure heater performance greatly effect to the efficiency of the boiler. High pressure heater performance is determined by DCA (Drain Cooler Approach), TTD (Terminal Termperature Difference), and Overall Heat Transfer Coefficient (U). This thesis aims to analyze performance of High pressure heater #1 in PLTU 1 Pacitan East Java. The main tool of this data collection is a High pressure heater #1 in PLTU 1 Pacitan East Java. Data collection was performed at 200 MW load in October 2013 and April 2014. The analyze result at 200 MW load in October 2013 can be seen that value of TTD - 6,334 °C, DCA 1,839 °C, U 2399,97 kj/h. m². °C. The analyze result at 200 MW load in April 2014 can be seen that value of TTD - 4,902 °C, DCA 1,979 °C, U 2096,5 kj/h. m². °C. High pressure heater #1 at 200 MW load have difference TTD 1,432 °C, DCA 0,14 °C, U 303,47 kj/h. m². °C. From the calculation known that the High pressure heater #1 PLTU 1 Pacitan East Java can’t work in good condition and the performance was go down. Key Word : High pressure heater, High pressure heater, High pressure heater, Drain Cooler Approach, Terminal Termperature Difference, dan Overall Heat Transfer Coefficient.
