Abstract:
A method of chilling inlet air for a gas turbine power plant, compromise:(a) passing inlet air through an air chiller that includes an opening for receiving the inlet air and that is operable connected to a gas turbine power plant that includes at least one gas turbine, and at least one gas turbine inlet which receives the inlet air; (b) passing liquid water through two or more sequentially positioned water chillers at a first flow rate to reduce the temperature of the liquid water, each water chiller including a conduit through which the liquid water is capable of passing; (c) passing the liquid water having the first flow rate through the air chiller in an amount sufficient to lower the temperature of the inlet air; (d) reducing the flow rate of the liquid water passing through the water chillers; (e) passing the liquid water through the water chillers at a second flow rate to reduce the temperature of the liquid water, the second flow rate being lower than the flow rate; and (f) passing the liquid water having the second flow rate through the air chiller in an amount sufficient to lower the temperature of the inlet air.
