Abstract

Low Pressure Heater adalah suatu alat yang digunakan untuk memanaskan air pengisi boiler dengan memanfaatkan uap ekstraksiturbin sebelum dikondensasikan di kondensor. Performance Low Pressure Heater sangat mempengaruhi efisiensi dari boiler. Performance Low Pressure Heater ditentukan oleh DCA, TTD, UD steam, dan UD Water Tugas akhir ini bertujuanu ntuk menganalisa Performance Low Pressure Heater 5 dan 6 di PLTU 1 Rembang. Alat utama dari pengambilan data ini adalah Low Pressure Heater 5 dan 6 yang ada di PLTU 1 Rembang. Pengambilan data dilakukan pada beban 215 MW dan 300 MW pada saat kondisi unit masih baru dan kondisi unit sudah lama beroperasi. Kondisi unit masih baru dengan kondisi unit sudah lama beroperasi dapat diketahui bahwa Low Pressure Heater 5 beban 215 MW kondisi DCA selisihnya 0,1°C, TTD selisihnya -1,42 °C, UD steam selisihnya 229,309 kj/h/m²°C, UD Water s elisihnya 224,153 kj/h/m²°C, beban 300 MW kondisi DCA selisihnya 0,2°C, TTD selisihnya -3,37 °C, UD steam selisihnya 39,718 kj/h/m²°C, UD Water selisihnya 39,718 kj/h/m²°C. Low Pressure Heater 6 beban 215 MW kondisi DCA selisihnya 0,04°C, TTD selisihnya -0,37 °C, UD steam selisihnya 151,469 kj/h/m²°C, UD Water selisihnya 227,893 kj/h/m²°C, beban 300 MW kondisi DCA selisihnya 0,5°C, TTD selisihnya -0,87°C, UD steam selisihnya 172,158 kj/h/m²°C, UD Water selisihnya 188,658 kj/h/m²°C. Dari perhitungan diketahui bahwa Low Pressure Heater 5 dan 6 di PLTU 1 Rembang Jawa Tengah masih dapat bekerja dengan baik. Kata kunci: Low Pressure Heater, Low Pressure Turbine, Performance Low Pressure Heater. Low Pressure Heaterisa device used to heat the boiler water filler by utilizing extraction steam turbine before itis condensed int he condenser. Performance Low Pressure Heater greatly effect the efficiency of the boiler. Low Pressure Heater Performanceis determined by the DCA, TTD, steam UD, and UD Water. This thesis aimsto analyze Performance Low Pressure Heater 5 and 6 at the plant 1 Rembang. The main tool of this data collectionis a Low Pressure Heater 5 and 6 is inplant 1 Rembang. Data collection was performed at load 215 MW and 300 MW when the unit was new condition and the condition of the unit has been operating. Condition of the unit was new to the unit has been operating conditions can be seen that the Low Pressure Heater 5215MW load conditions DCA difference is 0.1°C, TTD difference is -1.42°C, steam UD difference is 229.309kJ/h/m²°C, UD Water difference is 224.153kJ/h/m²°C, 300 MW of load conditions the difference is 0.2°CDCA, TTD difference is-3.37°C, steam UD difference 39.718kJ/h/m²°C, UD Water difference 39.718kJ/h/m²°C. Low Pressure Heater 6215 MW of load conditions DCA difference is 0.04°C, TTD difference is-0.37°C, steam UD difference is 151.469kJ/h/m²°C, UD Water difference is 227.893kJ/h/m²°C, the load 300 MW conditions the difference is 0.5°C DCA, TTD difference is -0.8°C, steam UD difference is 172.158kJ/h/m²°C, UD Water difference is 188.658kJ/h/m²°C. Of calculationis known that the Low Pressure Heater 5 and 6 in Central Java Power Plant 1 Rembang can still work well. Key Word : Low Pressure Heater, Low Pressure Turbine, Performance Low Pressure Heater.
