WATER LEAKED ANALYSIS IN THE GAS AIR HEATER IN PT CIREBON POWER SERVICE

PT. Cirebon Power Services is the first steam power plant (PLTU) in Indonesia that uses Supercritical Boiler technology. Combustion in a boiler using coal fuel produces hot gas which must be disposed of by utilizing a vacuum from the ID Fan and releasing it into the atmosphere. Gas Air Heater is a device that utilizes convection heat transfer from boiler exhaust heat to heat Primary Air and Secondary Air. The analysis was carried out by comparing the Gas Air Heater A and B through three parameters namely Air Leakage, X Ratio, and Efficiency. Data was collected from 31 December 2019 to 30 January 2020. The efficiency value of Gas Air Heater A was obtained 66% - 68% and Gas Air Heater B was 62% - 64%. The value of Air Leakage Gas Air Heater A is obtained 6% - 9% and Gas Air Heater B 10% - 12%. The value of X Ratio of Gas Air Heater A is 0.74 to 0.77, greater than Gas Air Heater B 0.68% to 0.71%.
