“…The various studies underline that the choice of each application is a multi-parametric task that depends on the climatic and economic conditions that dominate along with the power requirements that characterize the respective network ( De Lucia M. et al, 1996). The two main points that are deemed as viable solutions for the future and require further investigation are a decoupling of the refrigeration system from the actual peak times when prices are high and an integrated ► Power output Performance improvement after applying the GT inlet cooling method.…”

This work is concerned with the investigation of thermal energy storage (TES) in relation to gas turbine inlet air cooling. The utilization of such techniques in simple gas turbine or combined cycle plants leads to improvement of flexibility and overall performance. Its scope is to review the various methods used to provide gas turbine power augmentation through inlet cooling and focus on the rising opportunities when these are combined with thermal energy storage. The results show that there is great potential in such systems due to their capability to provide intake conditioning of the gas turbine, decoupled from the ambient conditions. Moreover, latent heat TES have the strongest potential (compared to sensible heat TES) towards integrated inlet conditioning systems, making them a comparable solution to the more conventional cooling methods and uniquely suitable for energy production applications where stabilization of GT air inlet temperature is a requisite. Considering the system's thermophysical, environmental and economic characteristics, employing TES leads to more than 10% power augmentation.

“…Various authors have demonstrated the competitiveness of IAC both in the production of electric power peaks (Ebeling et al, 1992, Ebeling et al, 1994, combined plant for base load production (Vend Der Linder et al, 1996) and cogeneration plants (De Lucia et al, 1993, De Lucia et a), 1995, Utamura et al, 1996. The possibility of using these systems for natural gas compression stations is still to be investigated.…”

Gas Turbine (GT) performance seriously deteriorates at increased ambient temperature. This study analyses the possibility of improving GT power output and efficiency by installing a gas turbine inlet air cooling system. Different cooling systems were analyzed and preliminary cost evaluations for each system were carried out. The following three cooling systems were considered in detail: a) Traditional compression cooling system; b) Absorption single-acting cooling system using a solution of lithium bromide; c) Absorption double-acting cooling system using a solution of lithium bromide. Results clearly indicate that there is a great potential for GT performance enhancement by application of an Inlet Air Cooling (IAC). Technical and economical analyses lead to selection of a particular type of IAC for significant savings in capital outlay, operational and maintenance costs and other additional advantages.

“…Authors found that air temperature reduction from the ambient condition to 15˚C increase the instantaneous output power between 8 to 13% and 11% additional electricity could be generated from the same gas turbine power plant. De Lucia et al [3] investigated the benefit of compressor inlet air cooling for gas turbine cogeneration plants with the comparative analysis of different cooling methods. These analyses have performed for the LM6000 gas turbine in a cogeneration plant operated in base load.…”

The gas turbine systems are some equipment; that have extensive industrial and military applications due to their unique characteristics. One of the major problems in association with utilization of gas turbines is the output power and thermal efficiency. One of the major methods that are used for increasing the power and thermal efficiency in this type of power systems is compressor's inlet air cooling. In this paper, the effect of fuel replacement for methane gasfired gas turbines with LNG and cooling the compressor's air inlet with the cold exergy of LNG fuel evaporation will be examined. In the first step, the energy balance equation is applied to the gas turbine with Methane and LNG fuel separately. Then the problem of fuel replacement in some mini and micro gas turbine has been examined and the appropriate engine with the most power and thermal efficiency is selected. In the next step, the exergetic analysis of considered systems is performed and exergetic parameters of the two systems are compared together. Finally, the advance exergy analysis is performed and effects of fuel replacement on exergetic cost parameter and environmental characteristics are evaluated.
