Abstract:
A closed-loop cooling scheme for cooling stationary combustion turbine components, the turbine having a cylinder and a blade ring, the cooling scheme comprising:an annular coolant inlet chamber, situated between the cylinder and the blade ring, for housing coolant before being distributed to the turbine components;an annular coolant exhaust chamber, situated between the cylinder and the blade ring and proximate said annular coolant inlet chamber, for collecting coolant exhaust from the turbine components;a coolant inlet conduit for supplying the coolant to said coolant inlet chamber, said coolant inlet conduit being in fluid communication with said annular coolant inlet chamber;a plurality of inlet channels, in fluid communication with said coolant inlet chamber and the turbine components to be cooled, for supplying the coolant to the turbine components;a plurality of exhaust channels, in fluid communication with the turbine components to be cooled and said coolant exhaust chamber, for directing the coolant from the turbine components; anda coolant exhaust conduit for directing the coolant exhaust from said coolant exhaust chamber, said coolant exhaust conduit being in fluid communication with said annular coolant exhaust chamber.
