| Abstract: | By adopting the finite-time thermodynamic theory and method,studied was the exergoeconomic performance of an irreversible intercooling recuperative Brayton cogeneration plant with a constant temperature heat source and derived was an analytic formula for calculating a non-dimensional profit rate and exergy efficiency.With the profit rate and exergy efficiency serving as the targets,an optimization was performed of the distribution of the heat conductivities and choice of the intermediate pressure ratio thro... |
