Abstract :
The condenser is a heat exchanger that receives heat from a Low Pressure Turbine or LP turbine which is then converted into water through a condensation process. Changing process is carried out by flowing steam into a room containing pipes. Hot steam will flow outside the pipes while water as coolant flows inside the pipes. The condenser is very influential for the unit performance, so the author will discuss the condenser effectiveness in the condensing zone by comparing some operating data from condenser side A and condenser side B of PLTU Jawa Tengah 2 Adipala. The data that was used to determine the condenser effectiveness are the operating data for condenser side A and condenser side B on December 13, 2019 (before overhaul) and March 3, 2020 (after overhaul) at optimal load. Based on data processing, the effectiveness value of condenser side A on December 13, 2019 (before overhaul) has a value of 0,265 while the effectiveness of condenser side B is 0,256. After the overhaul was carried out on March 3, 2020, the effectiveness condenser side A became 0,422 while the effectiveness condenser side B became 0,4061. Comparison of the effectiveness value condenser side A before overhaul and after overhaul increased by 0,157 (37.20%). While the effectiveness value condenser side B before overhaul and after overhaul increased by 0,1501 (36,96%).
