Nowadays, dependence on electrical energy is getting increased. With increase the needs of electrical energy, the quality of available energy need to be improved so it can really be used wisely. Steam power plant is the system of power plant that using coal as the energy sources. The exergy analysis is very needed to evaluate the system’s performance and find the rate of exergy destruction. E…
This paper presents exergy and energy analysis of steam power plant system at PT. Tanjung Enim Lestari Pulp and Paper (PT.Telpp) that aims to improve performance by analyze the components and the overall system. Energy analysis is able to know location, type and losses that occur during the process. Energy rate, exergy, energy and exergy efficiency and irreversibility is calculated based on the…
