Abstract
Kondensor merupakan salah satu jenis heat exchanger yang berfungsi mengkondensasikan fluida gas menjadi cair. Perawatan pada kondensor sangat dibutuhkan agar tidak terdapat kerak yang dapat mengganggu perpindahan panas didalam kondensor. Jika laju perpindahan panas rendah, mengakibatkan kerja netto akan semakin meningkat. Mengetahui peran kondensor sangat penting dalam suatu siklus, maka perlu dilakukan analisa laju perpindahan panas kondensor PLTU Blok III PT. PJB UP Gresik.
Data yang diambil dari tugas akhir ini adalah data rata-rata actual sebelum overhaul pada 02 Juni 2017 dan sesudah overhaul pada 15 Juli 2017. Metode perhitungan untuk menghitung laju perpindahan panas dan performa kondensor adalah Log Mean Temperature Different (LMTD) dan Effectivness – Number of Transfer Unit (NTU).
Dari hasil perhitungan, dengan data kevakuman yaitu 0,1106 bar sebelum overhaul diketahui bahwa laju perpindahan panas sebesar 83.930623 MW dengan efektivitas sebesar 0,9711. Dan setelah overhaul dengan kevakuman 0,1057 bar diketahui laju perpindahan panas sebesar 85,124902 MW dengan efektivitas sebesar 0,9843. Laju perpindahan panas pada kondensor dipengaruhi oleh kondisi kevakuman kondensor. Semakin tinggi kevakuman kondensor maka steam semakin mudah menuju kondensor, sehingga meningkatkan performa dari kondensor.
================================================================================================
Condenser is one type of heat exchanger that functions to condense gas fluid to liquid. Care on the condenser is needed so that there is no crust that can interfere with heat transfer in the condenser. If the heat transfer rate is low, the net work will increase. Knowing the role of the condenser is very important in a cycle, it is necessary to analyze the heat transfer rate of the condenser PLTU Block III PT. PJB UP Gresik.
The data taken from this final project is actual average data before overhaul on June 02, 2017 and after overhaul on July 15, 2017. The calculation method for calculating heat transfer rate and condenser performance is Log Mean Temperature Different (LMTD) and Effectivness - Number of Transfer Unit (NTU).
From the calculation results, with vacuum data which is 0.1106 bar before the overhaul it is known that the heat transfer rate is 83.930623 MW with an effectiveness of 0.9711. And after the overhaul with a vacuum of 0.1057 bar, the heat transfer rate is 85.124902 MW with an effectiveness of 0.9843. The heat transfer rate in the condenser is affected by the condition of the condenser vacuum. The higher the vacuum condenser, the easier the steam to go to the condenser, thus increasing the performance of the condenser.
