Elliott Turbine-Generator Sets

2

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, efficient 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 Elliott turbine-generator package configured 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-generator set gives users with steam systems a smart alternative for reliably, efficiently 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 first 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 staffing levels, many institutions such as universities, medical centers, correctional institutions and corporate campuses fit this profile.

The prevalent use of steam in industrial processes also identifies 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 as lumber, 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

• InstitutionalsteamsystemsBiomass and geothermal are also appropriate applications for Elliott steam turbine-generator sets.

A Heritage of Quality & ReliabilityElliott 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 efficiency. Elliott’s product line includes single valve single stage (SVSS), single valve multistage (SVMS) and multivalve multistage (MVMS) turbines.

Flexible, Efficient ConfigurationsAn Elliott back 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 converts thermal 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 provides high-efficiency condensing steam-turbine generators for applications where 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 flow. All Elliott turbine-generator systems are optimized to provide maximum pay-back based on varying steam and electricity demands.

Turbine-Generator Control SystemsElliott offers sophisticated, flexible, easy to use turbine-generator control systems. Standard control systems can be easily modified 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

• Automatic optimization of power generation with the available steam

• Utility paralleling

• Integrated circuit breaker

• Network communication and remote access

Complete packagesAn 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.
