Reaction Steam Turbines

Reaction Steam Turbines

Modular designs for customized applications in power & size

Our Reaction Steam Turbines are based on a modular turbine design to ensure reliability with highest performance. The machines are customized using pre-engineered, field-proven stator and rotor components optimized and tailored to the thermal cycle requirements to provide higher efficiency over the entire operating range.

Higher efficiency and reliability for any thermal cycle requirements

  • Inlet sections are selected from a large array of modules, with progressive temperature capabilities up to 565°C/1050°F to satisfy from the smallest to the largest power output requirements. The turbine exhausts are selected from a large array of backpressure and condensing modules available with either a radial or axial configuration. The low pressure stages are selected from a set of families of three-dimensional stages having variable or fixed speed capabilities to best match the specific application. The Intermediate pressure portion is composed of sub-modules to match specific plant process requirements.

    BHGE digital industrial company is harnessing the power of data to help our customers make better and quicker decisions and to make their operations and equipment as productive and efficient as they can be. Thanks to the digital twin approach and advanced sensors designed for on-line continuous steam turbines monitoring, it is now possible to benefit from digital solutions able to reduce commissioning time, increase working hours and optimize maintenance intervals. These features are already embedded in new turbines, while can be also applied on installed machine as small control panel upgrade.

    SC/SAC Series

    These single-flow turbines use both impulse and reaction blades for top efficiency over a wide range of operating conditions. Used in condensing configurations, they can have sliding and/or fixed pressure control, up to two controlled or six uncontrolled extractions, axial or radial (up/down) exhaust, and can be base or foundation mounted.

    SNC/SANC Series

    These turbines have the same features as the SC/SAC series, but are designed for backpressure configurations with dedicated exhaust modules.

    A5/A9 Series

    These single-casing steam turbines provide the most effective solution for small reheat, very compact design applications. They are configured with a central admission and back-to-back flow path to reduce temperature gradients and minimize thermal stress. Other features include bleeds and an extraction IP section, axial exhaust, sliding and/or fixed pressure control.

    SG Series

    SG series turbines, in single or double flow configuration, feature a unique design and materials to withstand direct geothermal steam conditions such as saturated or slightly superheated steam, corrosive contaminants, and low pressure. Options include, governing impulse or reaction blades, steam chest partializing system to deal with well depletion, inlet pipe mounted trip and control valves, and axial or radial (up/down/lateral) exhaust.

    SDF Series

    SDF double flow turbines have impulse and reaction blades designed to accommodate low pressure steam. They can be used like the low pressure body of a two casing turbine, or like a stand-alone turbine for low pressure steam conditions. Used in condensing configuration, they have sliding and/or fixed pressure control, and radial (up/down) exhaust and are typically used as a revamp option.

     

    Our Reaction Steam Turbines are engineered and built to provide excellent fit in a wide range of oil and gas applications, including urea, ammonia, ethylene, methanol, refinery, syn-fuels, process air, GTL, and LNG/FLNG. They also cover a variety of power generation applications, including combined cycles, cogeneration, waste-to-energy, and biomass, geothermal, and solar.
