An optimization procedure is presented for combined power plant heat recovery boilers (HRBs), which are the components with the greatest single impact on plant cost and efficiency. A calculation code was developed to solve the thermodynamic balance and compute the exergetic losses in a single-pressure HRB. The code was tested on three working fluids (water, ammonia, and a mixture of both). Results show that maximum energetic efficiency and maximum output are achieved separately, using different design parameters

Abstract
An optimization procedure is presented for combined power plant heat recovery boilers (HRBs), which are the components with the greatest single impact on plant cost and efficiency. A calculation code was developed to solve the thermodynamic balance and compute the exergetic losses in a single-pressure HRB. The code was tested on three working fluids (water, ammonia, and a mixture of both). Results show that maximum energetic efficiency and maximum output are achieved separately, using different design parametersFile in questo prodotto:
