Formulation of Exergy Cost Analysis to Graph-Based Thermal Network Models
Entropy, 2017 Information from exergy cost analysis can be effectively used in the design and management of modern district heating networks (DHNs) since it allows to properly account for the irreversibilities in energy conversion and distribution.

A Proposal of Ecologic Taxes Based on Thermo-Economic Performance of Heat Engine Models
Energies, 2009 Within the context of Finite-Time Thermodynamics (FTT) a simplified thermal power plant model (the so-called Novikov engine) is analyzed under economical criteria by means of the concepts of profit function and the costs involved in the performance of ...

Optimization of Steam Pressure Levels in a Total Site Using a Thermoeconomic Method
Energies, 2012 The present study aims to develop a thermoeconomic-based approach for optimization of steam levels in a steam production and distribution system by use of the specific exergy costing (SPECO) method for determining optimum steam levels to minimize the ...

Constructal law & thermoeconomics [PDF]
International Journal of Heat and Technology, 2016 In spite of evident differences, Constructal Theory and Thermoeconomics (in particular thermoeconomic optimization) have also some similarities. For instance, they both suggest the optimal allocation of two different types of losses: high permeability vs.
