    Highlights of the SGT-300 gas turbine

    In cogeneration configuration, with its excellent efficiency and high steam-raising capability, the SGT-300 forms the core of reliable, efficient and powerful combined heat and power plants. For industrial cogeneration, the high steam-raising capability of more than 18 tonnes per hour contributes towards achieving overall plant efficiencies of 80% or higher.

    For compliance with stringent environmental legislation, the SGT-300 gas turbine is equipped with a Dry Low Emissions (DLE) combustion system, providing low NOₓ emission levels with liquid and gaseous fuels.
    Emissions on gas fuel, corrected to 15% O₂ dry:
    NOₓ: < 15 ppmvd
    CO: < 10 ppmvd

    The SGT-300 operates on a wide range of gases, covering an extensive Wobbe fuel range. It is also able to burn a large number of liquid fuels and offers dual-fuel capability. You will benefit from automatic changeover from primary to secondary fuel at any load.

    The SGT-300 can be maintained on-site. Furthermore, the option of rapid core turbine exchange will minimize the downtime of your gas turbine.

    You can use the SGT-300 for a wide variety of power generation applications, including:

    • Simple cycle applications
    • Combined cycle applications
    • Cogeneration for industrial plants with high heat load, district heating schemes
    • Power generation for the oil and gas industry; e.g., onshore for use in oil fields or refinery applications, and offshore on platforms and FPSO vessels

    Typical mechanical drive applications are:

    • Drive solution for pumping applications, e.g., transporting of crude oil and refinery products, or as pump drive for water injection in oil production
    • Drive solution for compressors in gas injection, for pressure increase in pipeline applications, or in gas processing

    Ingenious design to the core

    The single-shaft SGT-300 consists of a single twin-bearing rotor with heavy-duty casing. Quick core engine exchange is possible, which significantly cuts your maintenance-related downtime.
    The SGT-300 twin-shaft has a 2-stage gas generator turbine and a 2-stage power turbine. The core turbine is designed for high reliability with powerful performance and quick load following. Its modular design approach allows turbine module exchanges to be carried out on-site as an alternative to a gas generator or power turbine service exchange.

    Both versions of the SGT-300 gas turbine are equipped with a Dry Low Emissions (DLE) combustion system, providing low NOₓ emission levels with liquid and gaseous fuels and dual-fuel capability.

     

     

    SGT-300 packages

    The compact SGT-300 gas turbine packages for power generation and mechanical drive applications comprise factory-tested modules, and offer a high power-to-weight ratio. The packages  incorporate gas turbine, gearbox (where applicable), drive unit and all factory-tested fluid modules mounted on an underbase, which you can easily transport, install and maintain on-site.

    The shop-tested and certified fluid system modules are the same for design across the SGT-100 to SGT-400 range and come fully wired into the package control systems:

    • Auto drains module
    • Gas fuel module
    • Lube oil module
    • Liquid fuel module (optional)

     

    The health and safety of the operation and maintenance staff are paramount. This is why our SGT-300 packages are designed with a special emphasis on, e.g., walkways and handrails, noise suppression, access doorways, and safety interlocks.

     

     

    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

    Powering a cogeneration plant

    The SGT-300-based CHP plant was required to help provide for the energy needs of 13,000 people living and studying at an university campus, in an efficient and cost-effective manner. The plant runs predominantly at part load, with various load adjustments, and provides trigeneration: heating, cooling, and electrical power.

    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 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.
