Effect of blade cooling on performance of a gas turbine power plant. Technical report No. 7
Technical Report
·
OSTI ID:6291812
The basic powerplant studied in this investigation is composed of a compressor, a burner, a cooled turbine, and an uncooled turbine. Each turbine is composed of an infinite number of infinitesimal impulse stages of polytropic efficiency eta/sub p/. The coolant air is supplied by a bleed connection from the discharge of compressor. The expansion ratio of turbine A varies so that the inlet temperature to turbine remains constant at the maximum allowable blade temperature. The coolant is compressed, passes through a heat exchanger and is ducted to coolant passages leading to the buckets and nozzles. Appropriate portions of the coolant, m/sub N/ and m/sub B/emerge from the nozzles and buckets, and, at states 6e and 6d respectively, mix with the main working fluid in the mixing chamber. The resultant mixture, now at state 7, expands through the uncooled turbine. The design and operating constants for this power plant are listed.
