I. Fukue et al., A NEW HIGH-EFFICIENCY HEAVY-DUTY COMBUSTION TURBINE 701F, Journal of engineering for gas turbines and power, 116(2), 1994, pp. 389-394
The 701F is a high-temperature 50 Hz industrial grade 220 MW size engi
ne based on a scaling of the 501F 150 MW class 60 Hz machine, and inco
rporates a higher compressor pressure ratio to increase the thermal ef
ficiency. The prototype engine is under a two-year performance and rel
iability verification testing program at MHI's Yokohama Plant and was
initially fired in June of 1992. This paper describes the 701F design
features design changes made from 501F. The associated performance and
reliability verification test program will also be presented.
