Abstract

Dengan kondisi sumber bahan bakar fosil yang semakin menipis pada saat ini maka diperlukan usaha penghematan energi dan pemakaian energi secara efisien. Tujuan penelitian ini adalah untuk mengetahui unjuk kerja PLTGU Tutong melalui kajian energi dan eksergi dengan menentukan empat skenario. Analisis energi dan eksergi dengan menggunakan program Cycle Tempo mendapatkan hasil efisiensi energi skenario 1 yaitu 49.26% hampir sama dengan efisiensi energi skenario 2 yaitu 49.1% dimana PLTGU beroperasi dengan beban GT dan ST yang sama tapi pada skenario 2 ST ASV mengalami kerusakan aktuator. Skenario 3 mendapatkan efisiensi PLTGU sebesar 47.6% dan dari skenario 4 diperoleh efisiensi open cycle sebesar 28.2%. Kehilangan eksergi terbesar terjadi di Kondensor yaitu sebesar 81.9% pada skenario 1 dan skenario 2 serta 83.4% pada skenario 3. Dari hasil ini terlihat bahwa kehilangan eksergi lebih besar terjadi pada skenario 3 dimana dua kipas ACC tidak berfungsi sehingga mengakibatkan rugi-rugi yang lebih besar akibat vakum di Kondensor yang tidak optimal. Kehilangan eksergi yang cukup besar juga terjadi di ruang bakar yaitu sebesar 15.1%, 15.05%, 15.6% pada skenario 1, 2 dan 3 serta 16.7% pada skenario 4. Kehilangan eksergi yang besar pada skenario 4 juga terjadi pada cerobong yaitu sebesar 16.7%.

With the current dwindling fossil fuel sources, efforts are needed to save energy and utilize energy efficiently. The purpose of this study is to determine the performance of the Tutong CCGT through energy and exergy studies by determining four scenarios. Energy and exergy analysis using the Cycle Tempo program obtained the results of energy efficiency in scenario 1, which is 49.26%, almost the same as the energy efficiency in scenario 2, which is 49.1% where the CCGT operates with the same GT and ST loads, but in scenario 2 the ST ASV experiences actuator damage. Scenario 3 obtained a CCGT efficiency of 47.6% and from scenario 4 obtained an open cycle efficiency of 28.2%. The largest exergy loss occurred in the Condenser, which was 81.9% in scenarios 1 and 2 as well as 83.4% in scenario 3. From these results it can be seen that greater exergy loss occurred in scenario 3 where two ACC fans were not functioning, resulting in greater losses due to the vacuum in the Condenser which was not optimal. Significant exergy losses also occur in the combustion chamber, namely 15.1%, 15.05%, 15.6% in scenarios 1, 2 and 3 as well as 16.7% in scenario 4. The large exergy loss in scenario 4 also occurred in the chimney, which was 16.7%.
