Study of Energy Losses in Steam Generation Unit and Efficiency Calculation

Steam generation is one of the most important energy consuming parts in the process industries. Approximately one-sixth of energy consumption in industries is used for steam generation. In this research utility unit of a chemical plant has been considered. Then, efficiency of boilers is calculated and major heat loss sources in process are identified. The results of calculation show that we can prevent lost of energy about 843096 sm3 of natural gas in year. This amount plus saving due to reduction of water consumption approximately 21% of fuel consumption price in this unit.
