Siemens Energy’s SGT-800 industrial gas turbine can now be operated on a wider range of fuels, including heavy hydrocarbons and diluted natural gas with up to 50% nitrogen content, while still maintaining impressive low emission levels.

The Dry Low Emissions (DLE) combustion system already achieves very low NOx and CO emissions in dual fuel applications, without having to resort to steam or water injection and without complex control systems, says Siemens.

The company believes that these new fuel flexibility initiatives will help increase its competitiveness in even applications in the oil and gas business, eg in LNG regasification plants. In addition, the 100th unit of this proven turbine was recently been sold to a refinery in Russia, where a critical project requirement for the gas turbines was their capability to operate on various fuels.

The Russian oil company Rosneft who has now ordered 13 SGT-800 gas turbines from Siemens, the latest being for 6 SGT-800s for the Tuapse refinery located on the shore of the Black Sea.
