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 ...

Fuel allocation in a combined steam-injected gas turbine (STIG) power generation and multi-effect thermal vapor compression (METVC) desalination system is studied, using seven methods: (1) Products Energy Method, (2) Products Exergy Method, (3) Power-Generation-Favored Method, (4) Heat-Production-Favored Method, (5) Basic Exergetic Cost Theory, (6) Functional Approach and (7) Splitting Factor M...

This work describes a large reclaimed water source heat pump system (RWSHPS) and elaborates on the composition of the system and its design principles. According to the characteristics of the reclaimed water and taking into account the initial investment, the project is divided into two stages: the first stage adopts distributed heat pump heating system and the second adopts the combination of ...

Although the gas turbine combined cycle (GTCC) system has better environmental performance, it still emits pollution gases such as CO2 and NOx. It is reasonable necessary to add cost power production of GTCC system. Based on structure theory thermoeconomics, through pricing pollutants (considering costs NOx emission), thermoeconomic (ETC) model developed in this study, which achieves absolute i...

Binary geothermal power plants (GPPs) are mostly encountered in fields with medium and low temperatures. The design operation of dual binary GPPs can be difficult due to the fluid properties. This affects their performance feasibility. Thermoeconomics essential elements for GPPs. In this study, advanced exergoeconomic analysis is applied a true GPP (as case study) further evaluate it from econo...

The aim of the paper is to identify consequence Constructal Principle in field Thermoeconomics (energy) production systems. This has been recently formulated as an extension Maximum Entropy Production and it used literature explain shape structure all kind flowing First, concept Thermoeconomic Environment defined consistently with consumption environmental resources residual emissions, which in...

Due to the importance of energy consumption in a steam network of oil refinery as a significant unit, present study is concerned with the optimization of an oil refinery steam network. Here, the attempt was made to use concepts such as first and second thermodynamic laws, thermo-economic, environmental and economic discussions to investigate three different scenarios about Tehran refinery steam...
