Thermoeconomic analysis method for cogeneration plants

Abstract

International Conference on Efficiency, Cost Optimisation, Simulation and Environmental Aspects of Energy and Process Systems, UNIV TWENTE ENSCHEDE, TWENTE ENSCHEDE, NETHERLANDS, JUL 05-07, 2000International audienceIn this paper, the authors present a unified comparison method for the calculations of thermodynamic efficiencies applied to combined heat and power. Three new indicators have been introduced: two energetic structure indexes defined to size up the CHP equipment, and a heat recovering ratio that allows to adapt the developed method to open cycles. A comparison between separated solution and prime movers has been studied by using this analysis tool. These indicators have been used to estimate the influence of technical and economical features
