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 parameters
