Peak performance with gas-fired system

Higher combustion temperatures are a key factor in improving efficiency. In the case of the new HL-class, combustion temperature has been boosted by around 100 kelvin. 

Our engineers also refined the compressor at the inlet of the gas turbine. As a result, it now only has 12 stages, one less than in the SGT-8000H series. This saves space within power plants and during the turbine’s transport. 

State-of-the-art gas turbines not only have to be extremely efficient — they also have to achieve the highest levels of flexibility due to renewable energy’s increasing share of the electricity mix. 

Get the most out of your resources: a combined cycle power plant with a single H-class gas turbine will achieve an efficiency of about 62 percent and a power output of 675 MW (50 Hz) or 472 MW (60 Hz).     

Reliably cover your electricity needs: daily startup to full load operation in less than 30 minutes plus rapid load changes – our flexibility solutions will equip your H-class power plant for any load requirements.

Reduce greenhouse gas emissions: an H-class power plant operates at high efficiency and with low emissions, even at part-load. We ensure that exhaust emissions are kept to a minimum even when starting up and shutting down – for you to comply with all relevant directives. We can even keep plants with SCR technology under 2 ppm NOx and CO while ramping with our unique Clean-Ramp™ technology.

Stay flexible: our F-class Flex-Plants can be quickly started up and shut down. This means that you can cover peak loads as efficiently as well and intermediate and base load demands.

Keeping an eye on costs: F-class power plants are especially service-friendly. Longer service intervals keep maintenance costs down – which means you get an ideal balance between capital costs, plant performance, and operating costs.

Whether you need a simple single-shaft configuration or multiple lines, or a system combined with a steam turbine or heat extraction all of these run reliably under extreme conditions.

Keep your options open: E-class power plants offer outstanding fuel flexibility – from low-calorific gases, gases containing CO₂, H₂S and N₂ to crude oil and other liquids with high viscosity.

Cover your peak loads: our E-class power plants can be rapidly started up, ramped and shut down. With no major efficiency losses, they are suited to operating with fluctuating power demand.
