Abstract

High Pressure Heater merupakan salah satu heat exchanger yang berfungsi untuk memanaskan air umpan (feed water) dari Boiler Feed Pump dimana media pemanasnya adalah uap ekstraksi yang diambil dari turbin tekanan tinggi. Performa High Pressure Heater ditentukan oleh TTD, DCA, effectiveness, dan U. Tugas akhir ini bertujuan untuk menganalisa performa High Pressure Heater 1 pada PLTU 3 Jawa Timur Tanjung Awar-Awar Tuban. Alat utama dari pengambilan data ini adalah High Pressure Heater 1 yang ada di PLTU 3 Jawa Timur Tanjung Awar-Awar Tuban. Pengambilan data dilakukan pada beban 340 MW saat kondisi unit komisioning (awal operasi) dan saat unit beroperasi pada kurun waktu tertentu, yaitu pada tanggal 03 Februari 2015, 03 Maret 2015, dan 04 April 2015. Hasil analisa data saat kondisi unit komisioning dan saat beroperasi pada kurun waktu tertentu dapat diketahui bahwa High Pressure Heater 1 nilai dari TTD = 0.882 C, DCA = 4.38C,  = 0.972, dan U = 493.957 W/m2C, saat beroperasi pada tanggal 03 Februari 2015 nilai dari TTD = 0.918C, DCA = 5.48C,  = 0.965, dan U = 451.308 W/m2C, saat beroperasi pada tanggal 03 Maret 2015 nilai dari TTD = 1.114C, DCA = 5.66C,  = 0.964, dan U = 454.816 W/m2C, dan saat beroperasi pada tanggal 04 April 2015 nilai dari TTD = 1.216C, DCA = 5.82C,  = 0.964, dan U = 448.159 W/m2C. Dari analisa diketahui bahwa High Pressure Heater 1 PLTU 3 Jawa Timur Tanjung Awar-Awar Tuban masih dapat bekerja dengan baik. Kata kunci : heat exchanger, High Pressure Heater, performa High Pressure Heater, NTU High Pressure Heater is one of the heat exchanger used to heat feed water from Boiler Feed Pump to Boiler by utilizing HP Turbine extraction steam. Performance of High Pressure Heater is determined by the TTD, DCA, effectiveness, and U. this thesis aims to analyze performance of High Pressure Heater 1 at the PLTU 3 East Java Tanjung Awar-Awar Tuban. The main tool of this data collection is a High Pressure 1 PLTU 3 East Java Tanjung Awar-Awar Tuban.data collection was performed at load 340 MW when commissioning and the unit has been operating, that is at February 03th, 2015; March 03th, 2015; and April 04th, 2015. Result of data analyze at the commissioning can be seen that value of High Pressure Heater 1 TTD = 0.882 C, DCA = 5.16C,  = 0.967, dan U = 444.08 W/m2C, at February 03th, 2015 value of TTD = 0.918C, DCA = 5.48C,  = 0.965, dan U = 395.61 W/m2C, at March 03th, 2015 value of TTD = 1.114C, DCA = 5.66C,  = 0.964, dan U = 394.779 W/m2C,and at April 04th, 2015 value of TTD = 1.216C, DCA = 5.82C,  = 0.963, dan U = 383.967 W/m2C. From the calculation is known that the High Pressure Heater 1 can still work well. Keyword : heat exchanger, High Pressure Heater, performa High Pressure Heater, NTU
