Abstract

Boiler efficiency is an important factor that affects the performance and reliability of a Steam Power Plant (PLTU), as it is directly related to fuel consumption and the electricity generated. A decrease in boiler efficiency can lead to energy waste and increased operational costs of the plant. Therefore, this study aims to analyze the boiler efficiency based on the generator output at the Bukit Asam PLTU and evaluate the efficiency of the turbines, generators, and the overall system efficiency of the plant. The method used is the direct method, utilizing actual operational data obtained from the control room, including steam flow rate, coal consumption, fuel calorific value, and generator output power. The research results indicate that the chemical energy of the fuel entering the boiler of 145.7 MW produces steam thermal energy of 92.99 MW, with a turbine efficiency of about 69% and a generator efficiency of 88%. The electrical power output of the generator produced is 56.46 MW, with an overall power plant system efficiency of 38.74%, showing that the performance of the Bukit Asam Coal-Fired Power Plant is still within a reasonable efficiency range for coal-fired steam power plants. Keywords: Boiler efficiency, Generator efficiency, Turbine, generator, coal fuel, plant efficiency
