“…The obtained results shows that the system appears to be capable of boosting generated power for about 11.07%. Santos et al [3] did the same study but applied to non-commercial gas turbine in Brazilian sites with increased power reached 9.65%. Hosseini et al [4] resulted in an increased output power of up to 13.3% which was applied to the combined cycle gas turbine power plant in Fars, Iran.…”

The study is intended to improve the performance of gas turbine engines in order to meet both electrical power demand and peak load in the power plant. In this paper, evaporative cooling system had been applied to improve the performance of gas turbine in Pesanggaran power plant in southern Bali Island, Indonesia. Moreover, the economic analysis was conducted to determine the capacity cost, operating cost and payback period due to the investment cost of the system. Based on the evaluation results, the power improvement for the three gas turbine units (GT1, GT2 and GT3) are 2.09%, 1.38%, and 1.28%, respectively. These results were not very significant when compared to the previous studies as well as on the aspects of SFC (Specific Fuel Consumption), heat rate and thermal efficiency. Based on the evaluation of the economic aspects, the reduction of production costs due to the application of evaporative cooling system was not economical, because it could not compensate the investment cost of the system and it resulted a very long payback period. These unsatisfactory results could be caused by the high relative humidity. Therefore, further studies are needed to investigate the other alternative technologies which are more suitable to the climate conditions in Indonesia.

“…The performance of plant when cooled is analysed using calculated values gotten from using (1)-(4) for point 1, 2 assumming that the evaporative inlet air cooler only cools the tempearture of the inlet air while point 3 and 4 are same as the data used in analysing the plant when uncoled as their temperatures remain unaffected by the evaporative inlet air cooler. The pressure of the system whether cooled or uncooled is same at point [1][2][3][4] In an ideal situation the temperature after cooling T1 will be the wet bulb temperature in Kelvin(K) but in a real operating situation T1 depends on the evaporative cooler effectiveness while Ta is the ambient temperature in Kelvin (K). …”

“…Evaporative cooler was selected because it is simpler and cheaper to operate and maintain [3]. The incorporation of an inlet air cooler to gas power plant reduces the compressor inlet temperature which results in reduction of turbine inlet temperature, thus increasing the turbine gross work output, the plant's efficiency and net power output.…”

The result of this study shows the performance of Ihovbor Gas Power Plant in Benin, Edo State Nigeria using first and second law of thermodynamics. Analysing the efficiency of the plant using first law of thermodynamics showed that with increase in inlet air temperature, the energy conversion efficiency of the plant reduces. The exergy efficiency of the plant also confirmed that increase in inlet air temperature results in decrease of the exergetic efficiency of the plant. Analysis of each of the components showed the greatest destruction of exergy was in the combustion chamber while the least is the Gas turbine section. Using numerical method in analyzing the gas turbine plant when retrofitting with an evaporative inlet air cooler showed better performance in energy conversion as power generation increased with an average of 1% per 1oC degree fall in temperature, the work ratio and thermal efficiency of the plant also increased. The analysis of the modified plant using second law of thermodynamics showed an increase in magnitude of both the exergy destroyed and the efficiency of the plant. Analysis showed that integrating evaporative cooler as component of the inlet air cooler increases the efficiency of the Air compressor by over 0.8% thus increasing the plant’s exergetic efficiency.

“…The clean combustion of the MGT theoretically contributes to the low vehicle emissions when operating in range extender mode compared to the internal combustion engine due to the continuous and complete combustion process of the air-fuel mixture [1][2][3]. However, the low gaseous emission such as NOx, CO and HC may deteriorate if the quality of the air mass flow is reduced such as in hot climate and high altitude areas [4][5][6]. In addition, the untreated air leaves deposits on the compressor and changes the aerodynamics profile of the air mass flow; and subsequently degrades the performance of the MGT over time [7,8].…”

AbstractA Micro Gas Turbine (MGT) can be considered as an alternative to the internal combustion engine as a range extender for electric vehicles. The MGT produces less raw exhaust gaseous emissions such as HC and CO in aerospace and static applications compared to the internal combustion engine. In addition, the MGT weight is less than an equivalent internal combustion engine and potentially can reduce the level of CO 2 further in a vehicle application. However, the use of the MGT in an automotive domain has some unique technical and commercial requirements that will require new validation approaches. An air filtration system is known to be one of the important elements to characterise the performance and the emissions of the MGT. In the past, most of the efforts on MGT were focused on the vehicle development and packaging studies, where the technical requirements of the test standards for the air filtration system were not considered. Furthermore, the validation techniques of the air filtration system for automotive applications have different requirements to those of a large scale turbine for aerospace use. A test method has been developed to investigate the effect of the automotive air filtration system on the MGT's characteristics in terms of the electrical power output and potentially the gaseous emissions. The outcomes of the research have provided good understanding of the MGT validation process in the automotive applications. It addresses the potential challenges that may hamper the MGT range extender for hybrid electric vehicle development processes.
