Power Generation

Whether you need power generation for

independent power production or for any

industrial application, the SST-400 steam

turbine offers you the flexibility, reliability

and economy of operation you demand.

The SST-400 range: proven designfor a wide range of applications

The SST-400 is a single casing steam turbine,

providing geared or direct drive to 1500 or

1800 rpm generators. It represents a solution

based on long experience of industrial steam

turbines, covering industrial applications such as:

Generator or mechanical drive

Industrial power plants, e.g. captive power

plants, chemical industry, pulp and paper

mills, sugar industry, textile industry, steel

works, mines

Cogeneration

District heating

Waste to energy, e.g. waste incinerators,

waste heat from chemical processes, bio-

mass plants

Combined cycle

The utilization of selected proven components

assures high reliability and easy maintenance.

Design features

The SST-400 single casing, modular package

design allows a wide variety of configurations

to satisfy the industrial customers individual

needs in the most economical way.

Turboset with SST-400steam turbine up to65 MW

The SST-400 turbine can be equipped with

upward, downward or axial exhaust orientation

to fit with the selected installation.

The turbine skid can be combined with standard-

ized gearbox-oil units and four pole generators

to a turboset, according to the customer's

needs.

The turbine skid and gearbox/oil unit are fullyassembled in the workshop before being

shipped to the site.

The pre-designed turboset enables early plan-

ning of the turbine building layout, saving time

for the customer.

Operational flexibility

Back pressure or condensing with internally

controlled extraction and possibility of several

bleeds allows the selection of optimal solutions

for the majority of industrial applications.

The design of the exhaust blades allows large

exhaust areas with high thermodynamic efficiency

and reliability.

The blading design provides for high efficiency

over the whole operation range, giving the

customer highly flexible plant operation.

The single body turbine has a symmetrical casing

with horizontal joint flange, which allows short

start-up times and rapid load changes.

The design of all supports for labyrinths and

blade carriers ensures flexibility for the whole

turbine.

Internal valve arrangements, controlling the

steam flow to the back end of the turbine, are

used to maintain constant process steam

extraction pressures over a wide flow range.

The rotor of the SST-400 range is made of solid

forging and is fitted with resonance-resistant

blading.

The reduction gears are taken from the existing

range of world class gear manufacturers and

have proven high reliability and performance.

Reliability and efficiency from proven technology

Easy maintenance

Our proven installation and maintenance con-

cept lowers maintenance cost by enabling easy

access to the installed components, the turbine,

gearbox, and generator.

Several maintenance concepts are available for

different modes of operation.

Quality and experience in one product family

SST-400 steam turbines are part of a modern

range of Siemens steam turbines developed to

meet the most demanding customer requirements

for cost-efficient power generation and mechani-

cal drive applications in power plants and industri-

al environments.

This is achieved by using a highly modularized

system of state-of-the-art components with well

proven design features. Its development is based on

experience accumulated during a century of steam

turbine design, manufacturing and operation.

The SST range of our turbines cover the complete

spectrum from 2 to 180 MW and are available in

back pressure, condensing and extraction design.

The table above shows the Siemens full range of

industrial steam turbines and their most important

parameters.

Whether you need a generator drive for power

generation or a mechanical drive for compressors,

blowers and pumps just tell us your needs and

together we can select the optimum turbine or

turboset which is most suited to respond to them.
