Abstract—This paper is about to study and compare cooling techniques and utilized systems to cool inlet air of power producing gas turbines. For years, the effect of lessening the temperature of the inlet air in the compressor on both the power and the efficiency has been known very well. Recently, fog pumping method as a substitute for prevalent evaporative coolers has been regarded and the cooling cycles for chilling inlet air in the gas turbines in order to decrease temperature to scale down the outlet power. To evaluate all selection or choices for applying cooling, the most arbitrary, possible method, in respect to the condition of exploitation and environment of site, causes power increase for producers and prevision of potential ability to cost frugality of users. These papers aim to describe and compare inlet cooling systems to gas turbines and especially fog pumping techniques with different environmental conditions in inlet gate. In spite of presenting the economical justification of studying systems not fully, but a relative analogy among given methods will be done.
Index Terms—Gas turbine, inlet air, vapourific chilling, fog pumping.
