Systematic quantification of intrinsic and induced malfunctions in the thermoeconomic diagnosis of a 350 MW coal-fired power plant

Abstract:

The aim of thermoeconomic diagnosis is to detect malfunctioning components in thermal systems and to quantify the additional fuel consumption caused by each one of them. Thermoeconomics provides tools for this task such as malfunctions, malfunction costs and fuel impact formula, whose applicability to real examples may be difficult due to induced effects. Besides, the quantitative causality analysis is a diagnosis method based on a thermodynamic description of the system. In this paper, both approaches are integrated by applying quantitative causality analysis to perform a systematic quantification of intrinsic and induced effects. The formulation is successfully applied to a coal-fired power plant.
