Abstract

Pembangkit Listrik Tenaga Uap merupakan pembangkit yang digunakan sebagai pemasok Sebagian besar energi di Indonesia. PLTU yang baik adalah PLTU yang memiliki performa dan efisiensi yang baik. Air laut dapat memengaruhi performa main equipment pembangkit yaitu kondensor. Hal ini disebabkan kondensor merupakan tempat untuk mengubah steam dari Low Pressure turbin menjadi liquid menggunakan air laut. Maka penelitian ini dilakukan untuk menganalisa akibat dari perubahan air laut terhadap performa dari kondenser beserta pembangkit. Data yang digunakan pada penelitian ini diperoleh dari Pembangkit Listrik Tenaga Uap Sulawesi Selatan Barru-2 yang berletak di kota Barru, Sulawesi Selatan. Penelitian ini menggunakan perangkat lunak HTRI Xchanger sebagai alat bantu pemodelan analisis perpindahan panas. Analisa penelitian ini berdasarkan data aktual kondensor PLTU sebagai landasan dalam melakukan variasi temperature inlet dan variasi mass flow rate sisi shell & tube. Hasil Penelitian ini adalah semakin tinggi temperature inlet sea water maka akan semakin rendah nilai effectivenessnya. Lalu variasi nilai mass flow rate juga memengaruhi nilai effectiveness yaitu semakin tinggi nilai mass flow rate baik pada sisi shell maupun tube, maka nilai effectiveness semakin tinggi pula. Lalu berdasarkan simulasi HTRI, didapatkan nilai mass flow rate paling optimal berada pada kecepatan 1.3 m/s. Tekanan vakum kondensor perlu dijaga pada kondisi ideal yaitu pada kondisi superheated steam agar kondensor dapat bekerja secara maksimal.

Steam Power Plant is a power plant used as a supplier of a significant portion of energy in Indonesia. A good Steam Power Plant is one that has good performance and efficiency. Seawater can affect the performance of the main equipment of the power plant, namely the condenser. This is because the condenser is where steam from the low pressure turbine is converted into liquid using seawater. Therefore, this research was conducted to analyze the effects of changes in seawater on the performance of the condenser and the power plant. The data used in this research were obtained from the Barru-2 South Sulawesi Steam Power Plant located in Barru city, South Sulawesi. The research utilized HTRI Xchanger software as a tool for heat transfer analysis modeling. The analysis was based on actual data from the condenser of the Steam Power Plant, which served as a foundation for conducting variations in seawater inlet temperature and variations in mass flow rate on the shell and tube sides. The results of this research showed that as the seawater inlet temperature increased, the effectiveness value of the condenser decreased. Additionally, variations in the mass flow rate also influenced the effectiveness, where higher mass flow rates on both the shell and tube sides resulted in higher effectiveness values. Based on HTRI simulations, the most optimal mass flow rate was found at a speed of 1.3 m/s. The vacuum pressure of the condenser needs to be maintained at an ideal condition, particularly in the superheated steam state, to ensure the condenser's maximum performance.
