Analytical method for evaluation of gas turbine inlet air cooling in combined cycle power plant

Thermodynamic Analysis of a Gas Turbine Power Plant Modelled with an Evaporative Cooler

“…The process of exchanging the sensible heat of the air for latent heat of evaporation from water is adiabatic [23]. Such a system is used as a preferred solution in dry/desert climate, which can be expected to boost the gas turbine power by nearly 12%.…”

A Calculation and Analysis to Determine Feasibility of Inlet Air Evaporative Cooling Systems for CCPP by Thermodynamic and Economic Method

“…The bold line (a-i) and (a-s) represent real cooling process and ideal theoretical cooling process, respectively. Some assumptions about the evaporative cooling system are made as follows: 1) the outlet RH of evaporative cooling system is 95%; 2) the air pressure drop in evaporative cooling system is 1% of atmospheric pressure [6].…”

“…Different inlet air cooling technologies of gas turbine and CCPP are introduced [1,2], and their benefits and drawbacks associated with the electric power load requirements and the climatic conditions are investigated [3][4][5][6]. Hosseini et al [7] modeled the performance enhancement of CCPP by media evaporative cooling system and investigated the effects of ambient temperature, RH and pressure.…”

Energy, Exergy and Thermoeconomics Analysis of Water Chiller Cooler for Gas Turbines Intake Air Cooling

“…In the direct method of evaporative cooling, the air intake cools off by contacts with a cooling fluid, such as atomized water sprays, fog or a combination of both, [Wang 2009]. Evaporative cooling has been extensively studied and successfully implemented for cooling the air intake in GT power plants in dry hot regions [Ameri et al 2004, Johnson 2005, Alhazmy 2004, 2006.…”
