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...
The power sector in Iran accounts for a share of 28.2 percent of the total CO2 emissions, so it is the biggest emitter of greenhouse gases. This study uses Logarithmic Mean Divisia Index (LMDI) technique to examine the role of five factors (economic growth, fuel intensity, electricity intensity, structure and quality of fuel) influencing CO2 emissions of the Power Plant sector in the period 1...
وجود معمای امنیت و پایداری آن کشورها را متوجه منطقه، تهدیدات و بی ثباتی های موجود در آن کرده است. تسلط تهدید، رقابت، اختلاف و خصومت، رقابت های تسلیحاتی و اختلافات سیاسی و ائدولوژیک از موانع عمده ی شکل گیری امنیت پایدار در مناطق است. در این میان چرخه ی قدرت یکی از مهم ترین ویژگی های سیستم جهانی و منطقه ای است که تاثیر مستقیمی بر موضوع مذکور دارد. لازم به ذکر است، که انواع چرخه های قدرت، سبب شکل ...
This paper presents the results of a research into the feasibility of recovering waste heat and determining design parameters of a recovery boiler for a set of medium-speed diesel generators with a capacity of 7 MW (the nominal capacity of all units is 42 MW, which would be a study on a unit). And is used to generate electricity. The main purpose of this study is to design a thermal waste recov...

The aim of the present paper is to examine the effect of ambient temperature on the performance of a combined cycle power plant. For this work, the combined cycle plant chosen is NTPC (National Thermal Power Corporation) Dadri, India where a gas unit of 817 MW is installed. The effect of ambient temperature on combined cycle efficiency, gas turbine cycle efficiency, exergy destruction in differ...
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 ...
