초록 ▼

A steam or air cooled combined cycle gas turbine includes first and second turbine stages and a second nozzle stage. During start-up, cooling air is supplied radially inwardly through the second stage nozzle for flow into the gas flow through the turbine and for combining with cooling air flowing radially outwardly from a high pressure compressor port. The combined air flow flows radially outwardly through the turbine blades. In normal operation, steam in lieu of air flows radially inwardly through the second nozzle stage and radially outwardly between the turbine wheels and spacer therebetween. Part of the steam through the nozzle stage combines with the radially outwardly flowing steam for cooling the turbine blades. The balance of the steam flows into the gas flow through the turbine. Combined steam/air cooling is effected for abnormally high turbine blade temperatures by combining cooling air from the high pressure discharge port of the compressor with the steam flowing radially outwardly through the turbine blades.

대표청구항 ▼

An integrated steam and air cooling system for a gas turbine comprising: a pair of axially spaced, rotatable turbine stages, each having a plurality of turbine blades for disposition in a gas flow through said turbine; a nozzle stage between said turbine stages and including a plurality of nozzle vanes for disposition in the gas flow through said turbine; means for supplying cooling air to and for passage through said blades and vanes to air cool said turbine; means for supplying steam to and for passage through said blades and vanes to steam cool said turbine; means cooperable with said cooling air supply means and said steam supply means for effecting a transition between air cooling said turbine and steam cooling said turbine; a turbine shaft, said blades and said vanes having interior passages, a spacer between said turbine stages and rotatable therewith, wheels about said shaft mounting said turbine blades and spaced axially from and on opposite sides of said spacer to define chambers on axially opposite sides of said spacer, said steam supplying means including first and second steam supply circuits, said first circuit including a steam supply, a channel adjacent said shaft and in communication with said steam supply for suppling steam to said chamber and said interior passages of said turbine blades, said second steam supply circuit including said steam supply, a manifold about said nozzle vanes for supplying steam from said steam supply to said interior passages of said nozzle vanes, means in communication between said interior passages of said nozzle vanes and said chambers for combining steam from said first circuit in said chambers with steam of said second circuit in said chambers, whereby the combined steam of said first and second circuits flows through the interior passages of said turbine blades.
