Gaz de France ordering high-efficiency drivers
For natural gas transmission, distribution, and storage operations, Gaz de France is installing Creusot-Loire's new line of high-efficiency gas-turbine packages, powered by Allison 501 and 570 generators for compressor speeds exceeding 10,000 rpm. The Type CA.3 driver comprises a 501 generator coupled to a two-stage power turbine; the ISO base rating is 3265 kW on gas fuel with a heat rate of 12,050 Btu/kWhr. The CA.5 driver with the stronger 570 gas-turbine engine is base-rated at 4805 kW with a heat rate of 11,360 Btu/kWhr. Designed for direct-drive, with no intermediary gearing, the high-speed compressor operates on the 13,820-rpm output shaft speed of the CA.3 for baseload requirements or on 11,500 rpm for the more powerful CA.5 set. These compressor packages will serve as boosters for the transmission and storage of regasified LNG from Algeria and natural gas from the North Sea, USSR, and France's own Lacq fields.
