Abstract

Boiler Feed Pump Turbine (BFPT) is a Turbine Driven Boiler Feed Water Pump and one of the important elements in the continuity of the operation of the Suralaya power plant. However, the long age and lack of maintenance intensity have an impact on BFPT’s performance. In November 2019-January 2020 a total BFPT overhaul was performed. To find out how much influence overhaul has on BFPT, an analysis is performed by comparing its performance between before and after overhaul. The analysis is based on the data taken, the results of the calculation of the decrease in boiler feedwater and the calculation of the efficiency of the BFPT through the Affinity Law method. From the analysis and calculation results show a decrease in efficiency of 3.16% for BFPT A and an increase in efficiency of 2.44% for BFPT B. The reduction of boiler feedwater flow is reduced by 28.67%, and although BFPT operates with lower rotation (4782 - 4990 rpm), lower flow rate (884 – 997 tons/h), and lower flow rate average (1713,28 tons/h) but the resulting load is still able to reach 600 MW. Keywords: Boiler Feed Pump Turbine, Overhaul, Efficiency Boiler Feed Pump Turbine (BFPT) adalah Pompa Air Umpan Boiler Berpenggerak Turbin dan merupakan salah satu elemen penting dalam kelangsungan operasional PLTU Suralaya. Namun usia yang sudah lama dan intensitas pemeliharaan yang kurang, berakibat pada menurunya kinerja BFPT. Pada bulan November 2019- Januari 2020 dilakukan Overhaul total BFPT. Untuk mengetahui seberapa besar pengaruh overhaul terhadap BFPT, maka perlu dilakukan analisis dengan cara membandingkan kinerjanya antara sebelum dan sesudah overhaul. Analisis didadasarkan dari data yang diambil, hasil perhitungan penurunan debit air pengisi boiler dan perhitungan efisiensi BFPT melalui metode Affinity Law. Dari hasil analisa dan perhitungan menunjukan terjadi penurunan efisiensi sebesar 3,16% untuk BFPT A dan kenaikan efisiensi sebesar 2,44% untuk BFPT B. Penurunan debit air pengisi boiler berkurang sebesar 28,67%, dan meskipun BFPT beroperasi putaran yang lebih rendah (4782 - 4990 rpm), debit air sisi keluar yang lebih rendah (884 – 997 ton/jam) dan rata rata debit air pengisi boiler yang lebih rendah (1713,28 ton/jam) namun beban pembangkit yang dihasilkan masih mampu untuk mencapai 600 MW. Kata kunci : Boiler Feed Pump Turbine, Overhaul, Efisiensi
