TL;DR: In this article, the authors present a new LENI-ARTICLE-1994-026 Record created on 2005-08-08, modified on 2017-05-10.

TL;DR: Thermo-economie functional analysis is a method for optimal design or improvement of complex thermal systems that minimizes the total cost of owning and operating the system, subject to constraints revealed by the functional diagram and analysis.

TL;DR: In this article, a gas-turbine cogeneration system with a regenerative air preheater and a single-pressure exhaust gas boiler is used as an example for application of three different analysis and optimization procedures: 1 (i) direct use of a nonlinear programming algorithm, 2 (ii) thermoeconomic functional approach, and 3 (iii) modular simulation and optimization of the system.

TL;DR: The principal approaches and methods for solving the optimization problem are described in brief and the uniqueness of the solution and the pos-sibility of finding this solution are discussed.

TL;DR: In this paper, a detailed analysis of the engines operation is performed to evaluate all thermal streams released by the engines and the thermal matching that maximizes the net power output of the total system composed by engine cooling circuits and ORC cycle is then found by searching for the optimum heat transfer between thermal streams independently of the structure/number of the heat exchangers.
