MODEL R
MULTI-STAGE STEAM TURBINE
The Dresser-Rand Model R™ multi-stage steam turbine
is a versatile, API 612-compliant turbine engineered to
meet demanding applications up to 25,000 kW. The multi-
stage Model R turbine is designed to drive generators
for independent power plants, compressors and other
mechanical equipment for industrial processing and
institutional power plants. These efficient steam turbines
also are used in food processing, ethanol, waste-to-energy,
and biomass applications.
CASING DESIGN
Casing splits (horizontal or vertical) are precision-ground with metal-to-metal
joints, eliminating the need for gaskets. Casings conform to ASME Section VIII
standards and NEMA standards for allowable stress levels; each section of the
turbine casing is hydrostatically tested to meet API 612 requirements.

designs.
OVERSPEED TRIP SYSTEM
The overspeed trip system is a two-out-of-three
electronic system with dual solenoid activation of an
independent trip-and-throttle valve.
The trip-and-throttle valve functions as a quick-
closing valve (manual or automatic) using electronic
trip actuators. It also functions as a manually
operated throttle valve for bringing the steam
turbine up to speed. Choose from a D-R mechanical
trip-and-throttle valve, or a Dresser-Rand Gimpel®
oil-operated trip-and-throttle valve.
DRESSER -RAND,
GOVERNORS
The Model R turbine is typically supplied with an electronic governor control
system. It provides tight control of speed (NEMA D) and includes an input for a
4-20 mA remote speed control signal that can be used for a process-generated
input to control the speed setting. Other features include dual-speed control
dynamics and overspeed trip test capabilities.
