Siemens has introduced a new SGT-800 performance enhancement suitable for all existing SGT-800 gas turbines with 43-47.5 MW ratings. The new upgrade is designed to provide owners and operators with significant fuel savings and reduce CO2 emissions.

Siemens said that the upgrade will give an improvement of up to 3.5 per cent in simple cycle gas turbine efficiency and up to an additional 10 MW output, to 53 MW. For combined cycle applications, the upgrade could result in a power increase of more than 20 MW and a 3.5 per cent lower heat rate, based on a combined cycle set-up of two SGT-800 gas turbines and one steam turbine.

The upgrade involves an improved compressor blade design to increase aerodynamic performance, as well as optimisation of the gas path mass flow and component cooling in the turbine section. The combined upgrades are designed to produce only a moderate increase in combustion chamber firing temperature.
