Steam Turbines
For nearly a century, Elliott steam turbines have earned a reputation as the most rugged, reliable and versatile drivers in the industry. Combining engineering expertise, rugged designs and precision manufacturing, Elliott steam turbines are built to perform and endure years of continuous service. These powerful workhorses provide exceptional value and performance in a broad range of processing, mechanical and power generation applications, around the clock and around the globe, in environments of every extreme.
Elliott steam turbines come in a variety of sizes ranging from small, 20 hp (15 kW) single-stage units, to large 135,000 hp (100,000 kW) multi-valve multi-stage extraction condensing units. These units can be built to API standards and can be customized to meet exacting customer specifications or other industry standards. With a large selection of both standard and engineered steam turbines and turbine generator sets, Elliott steam turbines boost production in industries as diverse as oil and gas, chemical and petrochemical, pulp and paper, power generation and food processing.

Elliott pioneered power recovery expander turbine technology in the 1950's and has been a leader in the field ever since. An Elliott TH power recovery expander turbine converts high temperature, low pressure flue gas energy into usable power. The turbine often is used to drive compressors or generators in refinery fluid catalytic-cracking (FCC) service. Recovery power for these applications can approach 50,000 hp (37,300 kW).
Elliott design engineers continue to advance expander technology to meet the changing demands of the FCC process. By using computational fluid dynamics to verify flow path design and minimize blade erosion, we have significantly extended typical time between turnarounds far beyond the industry average, without sacrificing efficiency. A number of Elliott expanders have exceeded 9 years of rated service without a blade change. To insure reliability, we design all critical components using finite element analysis. And we are continuously developing new coatings and materials to resist the erosive and corrosive environment of the FCC process.
Elliott power recovery expanders are the most dependable and durable designs in the industry.

Short reaction times and particularly high efficiency: the principles of a gas turbine and steam power plant are combined in a combined-cycle power plant. Efficiencies of up to 60% can be obtained by using a gas and a (downstream-arranged) steam turbine. Under combined operations (with integrated district heating supply) efficiencies of around 90% can be had.
In gas-fired plants as well, Hitachi Power Europe has both extensive know-how and a lengthy track record across the entire range stretching from planning via acquisition and design through to commissioning.
The highly successful and globally deployed H-25 / H-15 gas turbines from parent company Hitachi, Ltd. are the optimum ones for running power plants in a dependable, efficient and economical manner. Designed as a heavy duty machine (30 MW rating class), over 120 Hitachi gas turbines in power plants are in service throughput the world (as of mid-2009). The turbines are sound and dependable under continuous operations, involve low maintenance costs and are admirably suited for plants with cogeneration/district heating supply. Hitachi gas turbines are also used as power drive turbines in industry.

The blade tips of a turbine rotate some 3,000 times a minute and are thus faster than the speed of sound. The blades under extremely high steam temperatures (approx. 620 °C) and pressures (up to 250 bar) are subjected to extreme loads and stresses. Even so, it is expected of steam turbines that they are reliable and perform their work round the clock.
Hitachi, Ltd. has been supplying these kinds of highly efficient and reliable steam turbines for over 75 years now. Hitachi Power Europe's parent company has on offer turbines in the 250 to 1,380 megawatt (MW) rating class. Constant research and refinements ensure that these components belong to the best of their kind across the world.
The components (turbine and generator) are manufactured in the Hitachi works to the NE of Tokyo in Japan. Hitachi engineering teams not only carry out strict quality checks to ensure maximum performance and quality, but also provide ongoing and extensive support for their customers and service/upgrade the turbines.

Today's marine propulsion systems must provide faster vessel speed, enable greater payloads or deliver more power per square foot of machinery space. When vessel speed is critical and space is a premium, gas turbines can be an ideal solution.
For fast patrol boats, fast attack craft, corvettes and hovercraft as well as commercial applications such as fast ferries and mega-yachts, marine propulsion is made simple with Vericor's aero-derivative gas turbine-based power plants. Our marine propulsion offerings, ranging from 4,000 to 10,000 shp are based on the TF Series gas turbines.
Compact & Lightweight:
Our TF Series gas turbines are compact, lightweight and provide many times the horsepower over diesel engines for the same installed weight at a lower installed volume. With a cold-end drive, the gas turbine can be integrated into the package by cantilever mounting directly to the reduction gear, or mounting to a horizontal support frame and coupled to the reduction gear with a shaft and coupling.
The TF Series turbines can provide efficient power to a variety of propulsors including fixed and variable pitch propellers, waterjets and, in the case of hovercraft, air props. The small size and light weight features of the TF Series also allow for the installation of single or multiple gas turbines in combined system configurations.

Fuel injection valves
As components of pump-line-nozzle injection systems, conventional fuel injection valves ensure that when a defined opening pressure of the fuel supplied by the injection pump is exceeded, the fuel is injected very quickly in a uniform fine atomization. Here not only a precise begin of injection is very important but also fast closing at the end of the injection process. Proper static and dynamic design of the injection hydraulics prevents so-called needle shocks. This reliably prevents from even very minor unintended post-injection with after-dribbling effects, something that is necessary to ensure smokeless engine operation.

Greater power, higher efficiency and availability and rugged design are key issues for mechanical drive markets.
With more than 15 million hours of proven performance, the cornerstones of our VPS Series packages are the compact, rugged, and reliable ASE Series aero-derivative gas turbines. Space and weight are at a premium in some mechanical drive applications, and the VPS Series packages have the smallest footprint and highest installed power to weight ratio in their class. This means that VPS Series twin-shaft mechanical drive packages are well suited for centrifugal pump and compressor applications onshore and offshore.
Our packages are designed for reliability, efficiency and simplified installation. The proven design incorporates a simple cantilever mounting of the ASE Series gas turbine to the speed reduction gearbox. The close-coupled design of the VPS Series packages minimizes the footprint and eliminates alignment concerns between the gas turbine and gearbox.
