Model K

Multi-Stage Steam Turbine

The Dresser-Rand® Model K steam turbine is a cost-effective unit designed for

commercial and industrial applications where moderate load and steam conditions

prevail. With power requirements up to 7650 HP (5700 kW) and speeds to 10,000

RPM, the Model K steam turbine can be configured with one to nine stages to meet

a wide range of steam conditions.

The Model K turbine should be considered wherever a steady power source is

required over a wide speed range. Typical Model K turbine installations include chill-

er drives for universities, medical centers, and district energy applications, as well

as drives for compressors, process compressors, centrifugal pumps, fans and blow-

ers in the petroleum, petrochemical, paper, institutional, and food process industries.

Casing Design

A horizontally split casing with integral cast bearing bracket and heavy flanges

give the Model K turbine added strength. The integral gland cases, containing the

steam seals, provide a heavy gland boss at these points to maintain the integrity

and strength in this critical area of the casing. The reinforcing boss permits addi-

tional steam seals to be used resulting in less steam loss and longer running times

between seal changes. These and other design features help create an exception-

ally rugged and reliable turbine.

Inlet Valves

The Model K turbine is designed with a single inlet valve with optional manual hand

valves for steam flow control, and a wide selection of optional governors and acces-

sories.
