ANALISA PERFORMA EFISIENSI DAYA CONDENSATE EXTRACTION PUMP UNIT 1 PLTU 1 JAWA TIMUR PACITAN ( POWER EFFICIENCY PERFORMANCE ANALYSIS OF CONDENSATE EXTRACTION PUMP UNIT 1 PLTU 1 PACITAN, JAWA TIMUR )

Abstract

Tujuan pelaksanaan tugas akhir ini adalah memahami tentang cara kerja dan mengetahui performa efisiensi daya Condensate Extraction Pump berdasarkan perhitungan. Proses pengerjaan tugas akhir ini meliputi tiga tahapan. Pertama, tahapan persiapan. Kedua, tahapan pengumpulan data. Ketiga, tahapan pengolahan data dan perhitungan. Hasil perhitungan berdasarkan data yang telah dikumpulkan didapatkan bahwa efisiensi daya Condensate Extraction Pump A rata-rata pada bulan Oktober-November 2013 adalah 87,16% dan efisiensi daya Condensate Extraction Pump B rata-rata pada bulan Maret-April 2014 adalah 86,57%. Kedua pompa tersebut memiliki perbedaan nilai efisiensi sebesar 0,59%. Penurunan efisiensi disebabkan karena kebutuhan air kondesat menuju deaerator diatur sesuai dengan kebutuhan. Kerugin-kerugian head merupakan hal yang tidak dapat diabaikan dan harus diperhitungkan. Kata kunci: Efisiensi Daya, Condensate Extraction Pump, head loss The purpose of this final assessment is to get a new knowledge about how Condensate Extraction Pump works and to identify power efficiency performance based on some calculations. We have gone through 3 stages while we were doing this final assessment. The first stage is preparation, the second stage is collecting data and the last stage is processing and calculating data. As the result, power efficiency of Condensate Extraction Pump A in October-November 2013 is 81,57% and power efficiency of Condensate Extraction Pump B in March-April 2014 is 81,01%. The difference between power efficiency of Pump A and B is 0,56 %. The drop in efficiency is due to high demand for condensate water toward deaerator arranged in accordance with their needs. Loss of head loss is not negligible and should be taken into account. Keyword: power efficiency, condensate extraction pump, head loss
