Abstract :Thermoeconomic diagnosis is aimed at the detection of malfunctioning components in energy systems and the quantification of additional fuel consumption caused by each malfunction. A formulation is proposed based on: i); the use of enthalpy, entropy and flow rate for the characterization of flows within a system; ii); the linearization of restrictions; and, iii); the application of standardized indicators for variations in components behavior, set-points and system product. The approach allows one to introduce the concepts of thermoeconomic analysis insert ignore into journalissuearticles values(irreversibility and cost); to describe the process of fuel impact formation, without losing the capability of describing accurately the physical behavior of the system. A simple example is developed to illustrate the ideas presented. This paper is an updated version of a paper published in the ECOS`08 proceedings.
