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.
