Özet
In this paper, extensive analysis of the first and second laws of the thermodynamic is performed for a 14.25 MW cogeneration system, located in Adana, Turkey. Energy demand of the consumer is around 10.5 MW while the cogeneration system produces almost 1.35 times of the consumer requirement. The analysis results show that the largest irreversibility occurs in the boiler, which is 36% of the overall system irreversibility. Moreover, the economiser and chimney have further significant irreversibilities which are 34% and 25%, respectively. This paper also investigates the relationship between the steam pressure at the boiler output and system efficiency. As the steam pressure at the boiler output increases, the exergy destruction of the boiler decreases; therefore, the efficiency of the boiler increases. In addition, there is a satisfactory combustion efficiency in this cogeneration system since there exists high molar fraction value of CO2 at the chimney output.
