LM 2500

Combustion Turbine Generator (CTG)

The CTG is the prime mover for the DAI Oildale Enhanced Oil Recovery (EOR) Steam Facility. The CTG produces electric power, for sale to the local utility, through fuel combustion and furnishes exhaust heat to the Heat Recovery Steam Generator (HRSG) for the production of steam.

The CTG is a General Electric LM 2500 aircraft derivative gas turbine engine and a 13.8 kilovolt Generator manufactured by Brush Electric Machines, Limited. The CTG unit is designed and packaged by Stewart and Stevenson Services, Inc.

The LM 2500 gas turbine is based upon the CF6 family of turbofan engines used on wide-body commercial air transports, such as the DC-10. Capability for in-module maintenance and quick removal/installation of the gas turbine are unique features to aircraft-derivative designs.

The LM2500 is General Electric’s most experienced aero-derivative, with nearly 1,400 gas turbines delivered to date, and more than 18 million operating hours logged. This engine is capable of 31,200 shaft horsepower (shp) dry (23.3 megawatts/37.6% thermal efficiency) and 37,500 shp STIG (28 megawatts/41.3% thermal efficiency). The unit was introduced in 1969, and is used in a variety of power generation applications, including utility and industrial power generation and cogeneration. The LM2500 also is used by 24 navies worldwide on frigates, destroyers, cruisers, hydrofoils, auxiliary ships, carriers, patrol boats and corvettes, as well as in various commercial marine applications such as fast ferries.
