Abstract

Sistem pembangkit listrik telah berinovasi pada saat ini untuk tetap memenuhi kebutuhan akan ketersediaan listrik salah satunya dengan Organic Rankine Cycle (ORC). Sistem ini terdiri dari empat komponen utama yaitu evaporator, turbin, kondensor, dan pompa. Fluida kerja dipompa ke evaporator untuk membangkitkan uap lalu digunakan menggerakkan turbin. Uap hasil ekspansi turbin dikondensasi dan dialirkan oleh pompa kembali ke evaporator. Sistem ini mampu memanfaatkan sumber energi yang memiliki temperatur dan tekanan rendah untuk membangkitkan uap fluida organik. Penelitian ini dilakukan untuk membuat desain sistem Organic Rankine Cycle (ORC) serta bagaimana pengaruh pembebanan generator terhadap performa sistem. iv Setelah sistem berjalan steady dilakukan pengambilan data temperatur dan tekanan pada 4 titik yang diamati dengan thermocouple dan pressure gauge, serta pengaturan flowmeter dengan variasi pembebanan generator yang dilakukan dari beban kosong hingga generator tidak lagi berputar dengan indicator penyalaan lampu yang akan digunakan untuk mengetahui daya pompa, Q evaporator, Q condenser, daya turbin, efisiensi siklus, dan daya yang dapat dihasilkan siklus. Hasil yang didapatkan berupa perhitungan daya pada turbin 16090 watt,heat tranfer kondensor tertinggi 41832,831 watt, daya pompa 99,201 watt dan heat transfer evaporator 45235,656 watt, efisiensi thermal siklus tertinggi 36,15%, back work ratio tertinggi 2,67% pada flowrare 3 GPM. Power electric tertinggi 96 watt, Amper tertinggi 1,2 A, Volt tertinggi 190 V, Rpm turbin tertinggi 1547 Rpm. ===================================================================================================== Power system has been innovating at this time to still meet the need for electricity supply one with the Organic Rankine Cycle (ORC). The system consists of four major components, namely evaporator, turbine, condenser, and pump. The working fluid is pumped into the evaporator is used to generate steam and drive a turbine. The results of condensed steam turbine expansion and drained by the pump back to the evaporator. The system is able to utilize the energy source that has a low temperature and pressure to generate organic fluid vapor. The research was done to make the system design Organic Rankine Cycle (ORC) and the influence of generator load on system performance. Once the system is running steady performed data acquisition of temperature and pressure on four points were observed with thermocouples and pressure gauge and flowmeter settings with a variety of load generator made from an empty load to the generator is no longer rotates with the lighting indicators that will be used to determine the pump power, Q evaporator, condenser Q, power turbine, the efficiency of the cycle, and the power that can be generated cycle. The results obtained in the form of computation power on the turbine16090 watt, the highest heat transfer condenser 41832,831 watt , power on the pump 99,201 watt and the highest heat transfer evaporator 45235,656 watt, thermal efficiency of the cycle 36,15%, the back work ratio 2,67% on flowrare 3 GPM. The highest power electric 96 watt, the highest volts 190 V, the highest amps 1,2 A, turbine wheel 1547 Rpm.
