Abstract
Determining the maximum temperature of gas turbine is one of the challenges in energy conversion to achieve the suitable performance of gas turbine systems. For this purpose, based on the energy, exergy, environmental, and economic (4E) analyses, the effects of changing turbine inlet temperature (TIT) on a gas turbine power plant in northeastern Iran were studied. The results showed that increasing TIT enhanced net power and efficiency, so that increasing TIT about 10 K enhanced net power by 1.7%. Of course, on the other side, higher TIT increases the NOx emissions and the cost of materials and alloys. Therefore, the results indicated that higher TIT may not be necessarily more suitable. To find an optimal temperature, a price objective function was introduced in which the costs of power generation, net power, efficiency, and environmental taxes were effective. Finally, for the investigated power plant, the optimum TIT of 1328 K was introduced in which the cost of power generation could be minimized by about 0.115 $/kWh.

In this paper, the effects of various compressor inlet air cooling methods to increase the performance of Shahid Hashemi-Nezhad gas turbines refinery were investigated. These methods included media, fogging, and absorption chillers as common inlet air cooling methods and pressure drop station as novel cooling method. By using the exergy, environmental, and economic analysis, the best method for compressor inlet air cooling was selected. Based on the results, the absorption chiller system had the...

Abstract Today, there is a growing interest to produce biogas by anaerobic digestion process with regard to the decrease in fossil fuel sources, global warming, and the rising level of water, air and soil pollution resulted from drainage of the discharge of human and industrial wastewater, urban solid waste, and livestock dung in the environment. Furthermore, the high cost of biogas production equipment and instability in biogas production during different times and seasons increased the need to...

Abstract The highly dynamic nature of power demand forces a combined cycle gas turbine (CCGT) power plant to often run at less-efficient part-load conditions. A new operating strategy called EGR-IGVC is proposed in this work to improve the part-load performance of a CCGT plant. The strategy partially recycles the flue gas from the heat recovery steam generator and manipulates the inlet guide vanes to regulate part-load operation and boost plant efficiency. It allows the CCGT plant to set its own...

Abstract One of the methods of gas turbine performance improvement is steam injection into combustion chamber. Moreover, heat recovery is introduced as another method for enhancing energy and exergy efficiencies. In this paper, these two methods were combined in a system of Integrated Heat Recovery Steam Injected Gas Turbine (IHRSI) equipped with an anti-surge system. A heat exchanger was used for waste heat recovery of the gas turbine exhaust and steam production. In these conditions, due to th...

Hybrid power systems are being developed by the integration of fuel cell with conventional gas turbine. Integration of solid oxide fuel cell (SOFC) with gas turbine (GT) to form a hybrid cycle based power plant has been considered as this is known to be highly efficient primarily performance of SOFC being not limited to Carnot efficiency. In this article, a novel and optimal thermal integration of SOFC with intercooled-recuperated gas turbine has been presented. The novel contribution of this wo...

In power plant industry, it is always desirable that the performance of the plant should be as high as possible with the lowest possible investment. In this regard exergoeconomic analysis is a tool which combines thermodynamic analysis and economic principles to provide information that is helpful to predict thermodynamic performance and total cost of the plant. In this work an exergoeconomic approach is applied to the gas turbine based power plant cycles. In present work comparative exergoecono...

Abstract Recovering waste heat of gas turbines in order to power production and heat supply is one of the effective approaches in energy and environment management in offshore installations. In the present study, a gas turbine in the Draugen offshore platform was modeled and its exhaust waste heat was utilized to generate power through an ammonia-water cycle and supply the heat demand of the offshore facility. In order to optimize the combined heat and power system, pressure ratio, maximum tempe...
