GE - Model 7HA -Gas Turbine
GE’s 7HA high efficiency air-cooled gas turbine is one of the industry leaders among advanced class gas turbine offerings and is available in three models—the 7HA.01 at 290 MW, the 7HA.02 at 384 MW, and the 7HA.03 at 430 MW.
7HA gas turbine features and benefits
Whether your power plant operates at baseload or peaking profiles, you can count on GE’s 7HA gas turbine to deliver impressive performance.
The economies of scale created by the 7HA gas turbine, combined with its more than 64% combined-cycle efficiency, enables the most cost-effective conversion of fuel to electricity to help power plant operators meet increasingly dynamic power demands.
The 7HA suite of gas turbines’ flexibility enables increased dispatch and ancillary revenue, while enhanced fuel flexibility accommodates a wide range of gaseous fuels (shale gas, high ethane, H2) and liquid fuels (#2 diesel, crude oils). The 7HA gas turbine ramps up to full load in 10 minutes and features a novel configuration that supports simplified installation and maintenance.
GE’s DLN family (DLN 2/2.6/2.6+/2.6e) of combustion systems enables GE’s F-Class and H-Class gas turbines to reduce NOx emissions while enabling high plant efficiency plus extending outage intervals. The DLN 2.6e maintains many of the elements of GE’s DLN 2.6+ combustion system but introduces advanced premixing to the 7HA gas turbine combustor.
Simpler configuration and modular systems
The GE 7HA gas turbine portfolio facilitates easier installation with 10,000 fewer labor hours compared to F-class turbines. Additionally, its modular configuration also helps streamline maintenance with quick-removal turbine roof, field-replaceable blades, and 100% borescope inspection coverage for all blades. Its simplified dual-fuel system uses less water, eliminates recirculation, and utilizes enhanced liquid purge for improved reliability and dependability.
