Analysis of thermodynamic performance parameters and cost allocation methods in cogeneration systems

摘要

The aim of this paper is the development of a comparative analysis between some perofrmance parameters and some cost allociation methods,both well described in the literature.These parameters and criteria are based on ht eFirst and Second Laws of Thermodynamics - in the case of performance parameters - and on economic concepts as well as on energeti and exergetic concepts - in hte case of cost allocation mehtods.The study is applied to steam turbine cogeneration systems,assumign a typical worldwide sugar-cane mill.In these systems,the products are electric power,mechanic powe and steam to the industrial process.
