Description

The 9HA high efficiency, air-cooled gas turbine is an industry leader among H-class offerings, and now the 9HA.01 is at the heart of the world's most efficient combined-cycle power plant. With two available models—the 9HA.01 at 446 MW and the 9HA.02 at 571 MW—customers can easily select the right capacity to meet their generation needs. The world's largest and most efficient heavy-duty gas turbine. Thanks to a simplified air-cooled architecture, advanced materials, and proven operability and reliability, GE's 9HA units deliver exceptionally low life cycle cost per megawatt. The economies of scale created by this high power density gas turbine, combined with its more than 64 percent combined-cycle efficiency, enables the most cost-effective conversion of fuel to electricity to help operators meet increasingly dynamic power demands. •Streamlined maintenance with quick-removal turbine roof, field-replaceable blades, and 100 percent borescope inspection coverage for all blades •4-stage turbine with 3D aerodynamic hot gas path, cooling and sealing improvements, single-crystal and directionally solidified blades, and double-wall casing for improved clearance control •14-stage advanced compressor with 3D aerodynamic airfoils with superfinish, 3 stages of variable stator vanes, and field-replaceable blades •DLN 2.6+ combustor with axial fuel staging is proven through 45,000 starts and >2 million hours •Combustor enables improved turndown and greater fuel flexibility •Reduces need for on-site gas compression; fuel pressure requirements as low as 435 psi/30 bar •Reaches turndown as low as 30 percent of gas turbine baseload output within emissions compliance
