Analisis Perbandingan Efektivitas Closed Cooling Water Sebelum Dan Sesudah Pemeliharaan Pada PLTGU Blok 1 Priok POMU

Abstract

In the modern era, electricity has become a crucial component of various human activities. A Gas and Steam Power Plant (PLTGU) is one efficient solution that leverages the combination of gas and steam turbines. However, the effectiveness of the Closed Cooling Water (CCW) system at the Priok PLTGU is often hindered by fouling and performance degradation due to the accumulation of dirt in the heat exchanger. This research was conducted using data collection methods such as direct observation, interviews, and literature studies. Data analysis was performed quantitatively to compare the effectiveness of the Closed Cooling Water (CCW) system before and after maintenance at the Priok PLTGU Block 1. The research aims to analyze the comparison of CCW effectiveness before and after maintenance. The results showed an increase in effectiveness from 38.32% before maintenance to 46.29% after maintenance, although still below the commissioning figure of 53.75%. The maintenance carried out proved effective in improving the system's performance, but further improvements are still needed. The main factors affecting effectiveness include fouling and LMTD (Log Mean Temperature Difference). The suggestions provided emphasize the importance of routine maintenance and the use of high-quality materials to enhance CCW performance.
