Abstract
This research aims to determine the deterioration of boiler efficiency in Tanjung Jati B Unit 3 and 4 coalfired power plant with capacity 2x660 MW in Jepara Central Java Indonesia using energy balance (indirect method) based on ASME PTC 4-2018. The deterioration of boiler efficiency per year estimated using linear regression. From the results of the research, it is found that the deterioration in boiler efficiency of unit 3 is 0.19% per year and unit 4 is 0.44% per year. Large heat losses that vary for each performance test are greatly influenced by the use of various coal properties.
