title = "First and second law analysis of cogeneration plants",
abstract = "The present paper provides and evaluates an analysis of the cogeneration plant. The performance of the plant is evaluated by comparison to a conventional plant of separate units for producing process heat and power. The analysis is first- and second-law based and, therefore, quantifies the irreversibility losses of the different components of each plant. In the cogeneration plant, the heat required in the boiler can be either obtained from a fired boiler (condensing or back-pressure turbine plant) or from exhaust gases of a simple gas turbine (gas-turbine cogeneration plant). The present study provides a comparison of the two methods. The influence of the process heat-to-power ratio and the process pressure on the thermal efficiency, utilization factor and irreversibility rates of the different components of each plant is presented. The results show that the total irreversibility rate of the cogeneration plant is lower by 38% as compared to the conventional plant. This reduction in the irreversibility losses is accompanied by an increase in the thermal efficiency and utilization factor by 25% and 24%, respectively. The results also show that the most of irreversible losses are due to the boiler.",
