Abstract

Alat penukar panas atau Heat Exchanger (HE) merupakan suatu alat yang digunakan untuk memindahkan panas dari sistem ke sistem lain tanpa perpindahan massa dan bisa berfungsi sebagai pemanas maupun sebagai pendingin. Plate Heat Exchanger  ( PHE ) merupakan salah satu jenis Heat Exchanger (HE). Plate heat exchanger (PHE) adalah salah satu komponen penting dalam sistem gas turbin yang berfungsi untuk memindahkan panas dari gas turbin ke air pendingin dan merupakan salah satu komponen utama dalam sistem pelumasan turbin gas. Permasalahn yang timbul adalah Mengetahui apakah  nilai efektivitas pada  plate heat exchanger gas turbine   masih dalam keadaan normal atau sudah mengalami penurunan performa? dengan tujuan mengetahui dan menghitung nilai efekivitas  pada plat heat echanger (PHE) pada gas turbin. Metode yang digunakan pada perhitungan ini yaitu METODE-NTU.Pada METODE-NTU ( Number Of Transfer Unit ) ini efektivitas Plate Heat Exchanger (PHE) dapat diperoleh dengan perpindahan kalor nyata ( aktual ) dibagi dengan perpindahan kalor maksimum yang mungkin ( spesifikasi ). Data yang dibutuhkan pada perhitungan ini yaitu temperature inlet dan outlet water, temperature inlet dan outlet oil, flow rate water dan flow rate oil .Dari hasil perhitungan percobaan pertama didapatkan panas ( q ) aktual dengan nilai 57 Kw dan panas ( q ) maksimum dengan nilai 96 Kw sehingga efektivitas Plate Heat Exchanger (PHE) adalah 59 % , pada hasil perhitungan percobaan ketujuh didapatkan panas ( q ) aktual 44 Kw dan panas ( q ) maksimum dengan nilai 96 Kw sehingga efektivitas Plate Heat Exchanger (PHE) adalah 45 %. Dari hasil perhitungan percobaan pertama sampai ketujuh dapat diketahui Plate HeatExchanger mengalami penuruna performa.

Abstract

BSR-10 type biofuel pellet forming machine is widely used in renewable energy industry to produce high quality biofuel pellets. However, prolonged operation and heavy loads on these engines can cause their temperature to rise excessively and potentially damage the electric motors. To overcome this problem, this study aims to investigate the effect of using a Thermal Overload Relay (TOR) as a protection against overheating in a BSR-10 type biofuel pellet forming machine. This research involves measuring temperature and engine performance when operated with and without TOR. Motor temperature and engine ambient temperature are observed and recorded during normal operation and heavy load situations. In addition, engine performance in terms of rotational speed, energy consumption and pellet production were also evaluated with and without TOR. The results showed that the use of TOR significantly reduced the motor temperature in the BSR-10 type biofuel pellet forming machine. When given a heavy load, the engine that is protected by TOR shows a more stable and controlled temperature compared to the engine without TOR. In addition, TOR-equipped machines also show improvements in overall performance, including more stable rotational speeds, more efficient energy consumption and consistent pellet production. In conclusion, the use of Thermal Overload Relay (TOR) as protection against overheating in the BSR-10 type biofuel pellet forming machine is effective in controlling motor temperature, improving engine performance, and preventing damage caused by excess temperature. This research provides a better understanding of the use of TOR in the context of biofuel pelletizing machines and can provide useful guidance to the renewable energy industry in improving the operational efficiency and reliability of their machines..
