ANALISA PERFORMA EFISIENSI BOILER FEED PUMP TURBIN UNIT 1 PLTU 3 JAWA TIMUR TANJUNG AWAR – AWAR TUBAN ( PERFORMANCE ANALYSIS OF EFFICIENCY BOILER FEED PUMP TURBINE UNIT 1 PLTU 3 JAWA TIMUR TANJUNG AWAR – AWAR TUBAN )

Abstract

Boiler feed pump turbine merupakan pompa yang digunakan untuk suply air demin dari deaerator sampai ke steam drum di dalam boiler. Terdapat dua pompa BFPT yaitu boiler feed pump turbine A dan boiler feed pump turbine B. Pada Tugas akhir ini dilaksanakan untuk mengetahui nilai efisiensi yang paling efisien pada boiler feed pump turbine unit 1 PLTU Tanjung Awar-awar Tuban. Pengambilan data dilakukan pada beban 70 % (240 MW), beban 75% (255MW), beban 80% (272 MW), beban 85% (289 MW), beban 90% (306 MW), beban 95% (323 MW), beban 100 % (340 MW). Hasil analisa data dapat disimpulkan bahwa efisiensi pompa paling tinggi yaitu pompa BFPT A sebesar 81,60 % pada beban 340 MW dan terendah 68,55 % pada beban 240 MW . Efisiensi tertinggi pada BFPT B yaitu 79,67 % dan terendah dengan nilai 66,31 % pada beban 240 MW. Biaya operasional pompa tertinggi yaitu pada beban 340 MW dengan nilai sebesar Rp. 4.345.296. Kata Kunci : Boiler Feed Pump Turbine, Efisiensi, Boiler feed pump turbine is used to supply water from deaerator to the steam drum in the boiler. There are two pumps BFPT namely boiler feed pump turbine A and boiler feed pump turbine B. At the end of the task was carried out to determine the efficiency of the most efficient in the boiler feed pump turbine power plant units 1 Tanjung Awar-awar Tuban. Data were collected at 70% load (240 MW), 75% load (255MW), 80% load (272 MW), 85% load (289 MW), 90% load (306 MW), 95% load (323 MW) , load 100% (340 MW). Results of the data analysis it can be concluded that the highest efficiency pumps that pump BFPT A amounted to 81,60% at a load of 340 MW and the lowest is 68,55 % at a load 240 MW. Highest efficiency in the pump BFPT B with a value of 79,67% at a load of 340 MW and lowest efficiency is 65,9 % at load of 240 MW. Operating costs at the highest pump load 340 MW with a value of Rp. 4.345.296. Keywords: Boiler Feed Pump Turbine, Efficiency
