In this Article, a systematic approach of cost analysis and optimization for combining the multieffect thermal vapor compression (METVC) desalination system with the gas turbine power plant (GT) was proposed on the basis of thermodynamic, economic, and environmental attributes. The total annual cost (TAC) of the combined system, including annual capital and operating costs, was modified to define an efficient cost objective function by adding the exergy destruction cost as a lost opportunity cost, and environmental emissions cost as a damage cost of the system to the operating cost. A parametric analysis was conducted to evaluate the effects of the key thermodynamic parameters for combining the GT and METVC systems, including the gas turbine inlet temperature (TIT), the HRSG outlet temperature (HOT), and the temperature difference between the effects of the METVC system (ΔT METVC ) on the modified total annual cost (MTAC). The parameter optimization was achieved using a genetic algorithm (GA) to find the optimal key thermodynamic parameters with minimization of the MTAC of the combined system. In addition, the methodology was applied to optimize the combining of a METVC desalination system with a GT power plant located in Mahshar, Iran. The optimization results indicated that the METVC systems with less than five effects cannot be combined with the current GT power plant because the combined systems cannot produce the power and fresh water requirements. Among the combined systems with more than four effects in the METVC system, the combined system with five effects in the METVC system was selected as the best system, which can produce 28 543 m 3 /day fresh water and 127 MW power, respectively, and reduce the NO x emission by 3.6% as compared to the current power plant.

Due to increasing global energy demand and the fact that a major source of the required energy is generated from fossil fuels, the combustion process has turned into a topic of interest in converting fossil fuels to energy. An ideal combustion system is one that can combine high engine efficiency with low fuel consumption and low emissions. Increasing humidity is a technique used by researchers for influencing the combustion process. The present study aims to review previously conducted researches in this regard. Based on viewpoints of these researches, the reviewed studies were categorized into four groups: (1) the case studies used; (2) the methodology applied; (3) the design guidelines considered; and (4) the performance parameters studied. It can be concluded from the reviewed articles that nitrogen oxide (NOx) reduction is the most significant advantage of increasing humidity in the combustion process, and has led to the widespread use of this method. The other studied emissions either remained constant or their respective increases were negligible.

“…Ameri 4 indicated that in a simple gas turbine when the ambient temperature decrease from 34 °C to 15 °C, the net power output can be increased by 11%. Cardu and Baica 5 proposed a technical solution to realize the desired temperature in the combustion chamber of a gas turbine power plant by means of the injected water. Ganesan 6 studied the performance enhancement of standard gas turbine power plants using spray coolers at the air intake and suggested different cyclic arrangements to improve the net output and performance of the system.…”

Simultaneous energy and exergy analysis of power generation systems is essential for better understanding of the power generation processes, identification of inefficiency sources and effective utilization of energy resources. In this work, a detailed analysis of a standard gas turbine power plant system is presented from energy and exergy perspectives. The effect of various parameters such as inlet air conditions to the compressor, inlet fuel conditions to the combustion chamber, air preheating before the combustion chamber, steam injection to the combustion chamber and cycle temperature ratio were examined. Modeling results have indicated that lower inlet air temperature enhances the exergy and energy efficiencies and a higher net power output is achieved. It was also found that the steam injection to the combustion chamber increases the net power output and exergy efficiency and reduces NOx emissions considerably. The effects of fuel inlet temperature, pressure loss in the compressor air intake and gas turbine temperature ratio on the cycle performance are also investigated. The results of the present work highlight the direction in which engineers should concentrate their efforts to improve the performance of power generation systems.
