An Elliott steam turbine-generator set for the

generation of electricity is money in the bank.

An ever growing number of process plants and

institutions use reliable, efcient Elliott turbine-

generators to convert thermal energy from their

steam system directly into electricity. A portion of

the energy from steam produced for processes

or heating can often provide electrical energy

at lower cost than the utility supplier. An Elliottturbine-generator package congured to your

requirements can provide payback on your

cogeneration investment in three years or less.

The electricity marketplace has been transformed

in recent years. Deregulation, ever-increasing

demand, public resistance to new generating

facilities, environmental concerns, new

technologies and alternative sources of supply

have all complicated supplier selection, pricing

and distribution. An Elliott turbine-generatorset gives users with steam systems a smart

alternative for reliably, efciently and cost-

effectively meeting their electrical power needs

with on-site generation. And in many states

government subsidies encourage investment in

cogeneration systems.

The Right Mix

Cost-effective co-generation of electricity

begins with the right mix. The right mix means

rst of all a generally predictable demand

for steam. The second part of the mix is a

generally constant electrical load or a Power

Purchase Agreement. With alternating seasonal

demand for heating and air conditioning and

consistent stafng levels, many institutions suchas universities, medical centers, correctional

institutions and corporate campuses t this

prole.

The prevalent use of steam in industrial

processes also identies those plants as

excellent candidates for electrical co-generation.

Steam generation pressures and quantities often

exceed process requirements. With an Elliott

turbine-generator set, excess thermal energy

can be cost-effectively converted into electricity

rather than wasted. Many industries such aslumber, sugar and food processing utilize waste

material as fuel for low cost steam production.

Elliott turbine-generator packages are integrated

into many industrial applications including:

Chemicalsandpetrochemicals

Distilling

Foodprocessing

Primarymetals

Pulpandpaper

Sugarmills

Institutionalsteamsystems

Biomass and geothermal are also appropriate

applications for Elliott steam turbine-generator

sets.

A Heritage o Quality & Reliability

Elliott Company has designed and manufactured steam turbines for nearly a century. Tens of

thousands of Elliott turbines are in operation today. Around the world and over the course of millions

of hours of operation, Elliott turbines and turbine-generator sets have earned a reputation for high

reliability and efciency. Elliotts product line includes single valve single stage (SVSS), single valve

multistage (SVMS) and multivalve multistage (MVMS) turbines.

Flexible, Efcient Confgurations

An Elliottback pressure turbine-generator

unit can often be added in place of a

pressure reduction valve in an existing steam

system. The back pressure turbine can use

as little as 5% of the available thermal energy

to generate electrical power, with up to 95%

of the energy remaining available for process

requirements. After the turbine convertsthermal energy from the high-pressure steam

system into mechanical energy to drive the

generator, the exhaust steam is then used

for plant steam or industrial processes.

Depending upon steam conditions, a

backpressure turbine-generator can

produce electricity with little increase in fuel

consumption and no affect on downstream

processes.

Elliott provideshigh-efciency condensing

steam-turbine generators for applicationswhere there is no demand for low pressure

steam. Extraction /condensing turbine-

generator sets are available when the

demand for lower pressure steam is variable

and less than the available throttle ow.

All Elliott turbine-generator systems are

optimized to provide maximum pay-back

based on varying steam and electricity

demands.

Turbine-Generator Control Systems

Elliott offers sophisticated, exible, easy to use

turbine-generator control systems. Standard

control systems can be easily modied for

special requirements. Features include:

Touch screen interface for easy and

accurate control

Rugged construction, UL listed Fully automatic startup, synchronizing

and on-line control

Complete system monitoring

Complete packages

An Elliott turbine-generator set is a completely integrated package. Working from your requirements,

Elliott engineers design each unit to ensure trouble-free installation, start-up and operation. Elliott also

keeps lead times short and costs down through the use of standard, proven components.

A typical synchronous steam turbine-generator package includes a steam turbine, gear, couplings,

generator, baseplate, control systems and lube console. Elliott can also provide auxiliary systems

such as electrical switch gear and condensers. Directly connected induction generator packages are

available, as well.

This integrated Elliott

turbine-generator

package (above) includes

a multi-stage condensing

turbine, a speed reduction

gear and a 6 MW

synchronous generator.
