The optimization of the steam parameters heat recovery generators (HRSG) Combined Cycle Gas Turbines (CCGT) has become one important means to reduce power generation cost combined cycle units. Based on structural theory thermoeconomics, a thermoeconomic model for triple pressure reheat HRSG is established. Taking minimization system as objective, an algorithm based three factors and six levels ...

In order to investigate options for improving the maintenance protocol of commercial refrigeration plants, two thermoeconomic diagnosis methods were evaluated on a state-of-the-art refrigeration plant. A common relative indicator was proposed for the two methods in order to directly compare the quality of malfunction identification. Both methods were applicable to locate and categorise the malf...

The so-called Novikov power plant model has been widely used to represent some actual power plants, such as nuclear electric power generators. In the present work, a thermo-economic study of a Novikov power plant model is presented under three different regimes of performance: maximum power (MP), maximum ecological function (ME) and maximum efficient power (EP). In this study, different heat tr...

The use of the organic Rankine cycle (ORC), flash (OFC) and Kalina (KC) is proposed to enhance electricity generated by a supercritical CO2 recompression Brayton (SCRB) cycle. Novel comparisons SCRB/ORC, SCRB/OFC SCRB/KC integrated plants from thermodynamic, exergoeconomic sustainability perspectives are performed choose most appropriate bottoming for waste heat recovery SCRB For comprehensiven...

• Novel geothermal systems are proposed for combined cooling and power generation. Parametric multi-objective thermoeconomic optimization comparisons performed. System Conf.
