GE Power HA-Class Gas Turbine Fuel Nozzles
HA-class gas turbine fuel nozzles (world's most efficient gas turbines)
Energy/Oil & Gas85% confidence
Challenge
GE's HA-class turbines target the highest efficiency ratings (~64% combined cycle). Fuel nozzle complexity is central to combustion performance — conventional designs limit achievable cooling geometry.
Solution
DMLM-printed fuel nozzles with integrated micro-cooling channels enable combustion temperatures and efficiencies impossible with conventional nozzles. Part of the 9HA engine suite.
Outcomes
- 01Successful AM implementation
Technologies
Laser Powder Bed Fusion
Source
9HA and 7HA turbines with AM nozzles in service at power plants globally
