Abstract: Energy sector is one of the important areas in the economic development of any country. Meeting the growing energy demands at acceptable costs in various sectors like industries, commercial, transport, etc., is the challenge to the energy planner. Energy analysis helps to designer to find out to improve the performance of a system. The energy losses from individual components in the plant are calculated based on these losses. In this first law of thermodynamics analysis was performed to evaluate efficiency and various energy losses. In addition, variation in the percentage of carbon in coal content increases the overall efficiency of plant that shows the economic Optimization of plant.

Keywords: Energy, Boiler, First law of Thermodynamic, Efficiency, Energy losses, Optimization.
