Alstom - Model GT24 and GT26 - Gas Turbines
From Gas Power
Power producers around the world continually strive to increase their competitiveness and profitability by saving fuel, reducing operating costs, and delivering cleaner and reliable power. Alstom’s high performance advanced class gas turbines, the GT24 for 60 Hz applications and the GT26 for 50 Hz markets, deliver the efficiency, high availability and lower environmental impact to meet these challenges. Operators of gas-fired power plants gain peace of mind from knowing that Alstom’s decades of innovation and operating experience stand behind every GT24 and GT26.
One of the most reliable gas turbine solutions on the market, the GT24/GT26 gas turbines have amassed a strong performance record, including 6 million fired hours and 98,000 starts. The highly efficient GT24/GT26 turbines’ advanced design features annular combustors, welded rotors and unique sequential combustion technology. This powerful combination of innovative features allows the GT24/GT26 to achieve high performance output. The turbines’ combustion technology, which is exclusive to Alstom, burns fuel in two, dry low-NOx combustor stages.
Designed to accommodate fluctuating fuel types, Alstom’s gas turbines also deliver a choice of operating modes – performance optimised or maintenance cost optimised. The first produces maximum performance and output, while the second allows for longer intervals between service, reducing maintenance costs. Gas power plant operators can switch between these modes of operation in real-time while the power plant is on-line. No changes to hardware are required.
Competitive kilowatt hour
In combined-cycle applications, the GT24/GT26 is capable of producing high efficiency over a wide load range, using proven gas turbine technology.
Conventional turbine inlet temperatures, a uniform annular temperature profile, a maintenance-free, welded rotor and a simple and robust EV burner all help to reduce maintenance needs and therefore improve availability.
High power density
High power density designs lead to smaller components. Compared with Alstom’s medium-class gas turbines, the GT24/GT26 provides up to 60% more output for the same footprint. GT24/GT26 Right technology, The highly efficient GT24/GT26: the result of extensive experience and evolutionary development.
Sequential combustion means unrivalled operational flexibility, including the ability to handle wide fluctuations in gas compositions. With an operating range down to 20%, lowload operation and low NOx emissions, the plant can meet all power demands. And the GT24/GT26 is capable of switching online between performance-optimised and maintenance-costoptimised modes.
Sequential combustion technology is the industry‘s most innovative platform for clean power generation, resulting in gas turbines with low emissions and high efficiency.
