Daftar Isi:
- �Heat exchanger� serves as a heat exchanger which utilizes heat from a fluid flow. In the system of Tanjung Jati B power plant Units 1 & 2 especially in the steam cycle also apply the principle of heat exchangers. Performance of the heat exchanger in the steam cycle (Low Pressure and High Pressure Heater) can cause a decrease in the efficiency of heating water in the boiler when the heat transfer capability on the water heater down. Decreased ability to transfer heat is caused by damage which is common in the feedwater heater, which is damage to the pipe. This pipe damage can be caused by several things such as: erosion due to steam, pipe vibration, erosion and corrosion of the inlet pipe, stress caused by \"corrosion cracking\", and so on. This final project report will analyze the efficiency of heat transfer calculations on the elements of the Heat Exchanger, especially in LP and HP Heater before and after overhoul. The calculations include Balans Energy (energy balance), calculate effectiveness (ηthermal) on the Low Pressure and High Pressure Heater elements, calculate the heat transfer load (Q), calculate the logarithmic mean temperature differences (LMTD), and calculate the temperature efficiency (η) of elements before and after outage. After calculation showed no significant change in the value of the performance, there are only a heater are experiencing an increase in performance. Also due to the lack of decline in the performance of this tool feedwater heater, new operating approximately 5 years.
