SGT-300 gas turbine

Cogeneration plants

With its excellent efficiency and steam-raising capability of more than 18 tonnes per hour, the SGT-300 forms the core of reliable, efficient and powerful combined heat and power plants (CHP). This contributes towards achieving overall plant efficiencies of 80% or higher.

When compared with conventional energy supplies, a cogeneration plant based on the SGT-300 will provide electrical power, heating and/or cooling with the benefit of:

• significant reductions in energy costs
• security of energy supplies
• reductions in total emissions of carbon dioxide
• improved flexibility

Comprehensive portfolio of customer service activities

Our comprehensive portfolio of services provides low life cycle cost and optimum performance throughout the turbine’s life cycle: Long Term Programs (LTP), overhaul service, field service, spare parts, service exchange, remote diagnostic service, and modernization and upgrades.

Siemens specialists offer on-site support all over the world.

The SGT-300 is designed for easy maintenance:

• Horizontally split compressor casing
• Horizontally and vertically split inlet casing
• Large side doors on enclosure for equipment exchange
• Internal lifting equipment
• Package designed for gas turbine removal on either side

Coverage of a wide Wobbe range

The single-shaft SGT-300 operates on a wide range of gases, including gas fuels outside of standard pipeline quality. It covers a Wobbe fuel range from approximately 50 MJ/m³ down to 17.5 MJ/m³, which include, e.g., gas fuels available in LNG liquefaction plants, wellhead gas and minimally processed, weak wellhead gas, biogas from ethanol, industry waste, or landfill gas. The engine, equipped with DLE burners, is capable to burn up to 30 vol% of hydrogen (H2).

The SGT-300 is also able to burn a large number of liquid fuels and offers dual-fuel capability, with automatic changeover from primary to secondary fuel at any load.

Low emissions despite rugged industrial design

The proven and reliable Dry Low Emissions (DLE) combustor offers clean combustion with low emissions over a wide operating range.

The SGT-300 uses six reverse-flow tubular combustion chambers positioned around a high-pressure casing. Each burner contains its own ignition source and is capable of gas-only, liquid-only or dual-fuel operation. Fuel is controlled by both a pilot and a main burner, with the control system providing for smooth changeover across the power range.

With the DLE combustion system, emission compliance at lower operating loads down to 50% or lower is possible.
