Environment and the need to protect and care for it, is one of the main concerns of industrial development in todaychr('39')s society; and air pollution is one of the most noticeable and tangible causes of it. The increasingly growth of the industry has led to the production and diffusion of gaseous pollutants into the air and among them; thermal power plants are one of the most important sourc...

Exergy analysis is based on combined first and second laws of thermodynamics and is a useful tool to analyze the energy systems in a better and more realistic way than an energy analysis, based on the first law of thermodynamics. Combination of exergy from thermodynamics with conventional concepts from engineering economy which is referred to as thermo-economy (exergo-economy) is a valuable too...
in this paper, a new combined power and refrigeration cycle is proposed, which combines the rankin power cycle and the ejector refrigeration cycle. this combined cycle produces both power output and refrigeration output simultaneously. this cycle is driven by the flue gas of gas turbines, industrial waste heats, solar energy and geothermal energy. an exergy analysis is performed to guide the th...
In this paper, the feasibility of using heat energy of steam turbine combined cycle power plant as the energy required to start up desalination systems has been studied. The optimal model of combined cycle power plant equipped with a multi-effect desalination plants in different design modes of the effects of desalination and steam pressure of the steam turbine output has been evaluated. In ord...

In this study, a combined cycle power plant with a nominal capacity of 500 MW, including two gas units and one steam unit, was considered by the mathematical model of thermodynamic modeling and the results of the modeling were controlled by the design information of the system. Then, the objective functions are optimized by considering the decision variables. In this multi-objective optimizatio...
in this paper, a recurrent fuzzy-neural network (rfnn) controller with neural network identifier in direct control model is designed to control the speed and exhaust temperature of the gas turbine in a combined cycle power plant. since the turbine operation in combined cycle unit is considered, speed and exhaust temperature of the gas turbine should be simultaneously controlled by fuel command ...
Exergy analysis of an integrated molten carbonate fuel cell-turbo expander-steam turbine hybrid cycle has been presented in this study. The proposed cycle has been used as a sustainable energy approach to provide a micro hybrid power plant with high exergy efficiency. To generate electricity by the mentioned system, an externally reformed molten carbonate fuel cell located upstream of the combi...
