Abstract

Salah satu jenis pembangkit yang banyak di gunakan adalah pembangkit listrik tenaga uap (PLTU) yang bekerja dengan siklus rankine. Salah satu cara meningkatkan efisiensi sebuah PLTU dengan menambahkan feedwater heater yang berjenis high pressure heater (HPH). HPH berfungsi meningkatkan temperatur air yang akan dipanaskan di dalam boiler, sehingga pemasukkan bahan bakar lebih sedikit dibandingkan tanpa HPH. Namun dalam kondisi aktual, HPH sering menghadapi masalah sehingga dilakukan perbaikan yang mengharuskan HPH off service. Diperlukan studi lebih lanjut untuk mengetahui pengaruh off service HPH terhadap performa pembangkit. Penilitian ini memvariasikan off service HPH menggunakan analisa termodinamika dengan bantuan software Gatecycle. Semua perhitungan menggunakan parameter input tekanan dan temperature uap yang sama pada boiler dengan memvariasikan jumlah laju bahan bakar. Berdasarkan Piping and Instrumentation Diagram (PID) dan data properties dari PT. PJB Gresik, permodelan dilakukan di dalam Gatecycle sehingga dapat dilakukan pemvariasian sebanyak tujuh variasi off service HPH. Hasil penelitian yang didapatkan adalah pengaruh komposisi off service HPH terhadap pembangkit berupa efisiensi boiler, daya pembangkit, heat rate, dan efisiensi pembangkit. Semakin banyak jumlah HPH dalam kondisi off service, semakin tinggi efisiensi boiler, namun semakin rendah efisiensi pembangkit. HPH yang paling berdampak buruk terhadap efisiensi pembangkit ketika dalam kondisi off service adalah HPH kedua. ============================================================================================ Type of plant that commonly used is steam power plant which works with rankine cycle. How to improve efficiency of a power plant by adding a feedwater heater manifold high pressure heater (HPH). HPH works to increase temperature of water to be heated in the boiler, so use of fuel is less than without HPH. However, in actual conditions, HPH often face problems that do repairs that require off service of HPH. Needed to research the effect off service HPH to power plant performance. This research varying off service HPH using thermodynamic analysis with simulation of Gatecycle software. All calculations using the input parameters of pressure and temperature at the same steam boiler by varying the amount of the rate of fuel. Based from Piping and Instrumentation Diagram (PID) and data properties of PT. PJB Gresik, modeling Gatecycle with varying seven variations off service HPH. Research results obtained the effect of the composition of off service HPH to boiler efficiency, power generation, heat rate, and power efficiency. Increasing the number of HPH in conditions off service, will increase efficiency of boiler, but decrease efficiency of power plant. HPH most adverse impact on plant efficiency when off service is second HPH.
