As its name suggests, a steam turbine is powered by the energy in hot, gaseous steam and works like a cross between a wind turbine and a water turbine. Steam turbines are designed to transfer energy from fluid to the rotor which can be used as a generator drive for power generation or as a mechanical drive for your rotating equipment such as compressors and pumps.

In a steam turbine, the high-velocity steam is made to strike on the turbine blades. As the steam strikes on the blades, it rotates the rotor of the turbine. The generator is connected to the gas turbine also starts rotating and produces electricity. They are considered the most economical and flexible turbines that you can get.

The primary difference between gas turbine and steam turbines is the fact that steam turbines receive power from expanding steam. Several factors play an essential role in choosing the best turbine for your application. Here we compare some attributes between these two.

The SST-800 steam turbine can be used for both condensing and back-pressure applications. Turbine auxiliary systems are also designed as pre-engineered modules covering the complete range of turbine sizes.

The straight flow turbine solution with power output of up to 250 MW consists of a geared high-pressure steam turbine (backpressure), an intermediate / low-pressure steam turbine (condensing), both driving a generator installed in between.

We deliver a standard steam turbine generator set including the SST-600 (with or without gearbox), a generator, oil system, piping and instrumentation and the control system. The standard package can be extended to include a condenser, condensing plant or pre-heating system. The SST-600 with its reliable and flexible design is available with axial or radial exhaust.

The SST-500 is a single casing, double exhaust flow steam turbine, which can be used as an entire drive or as the lowpressure module of a multiple-casing turboset, directly driven or geared. This turbine, with its capacity to operate over a wide range of speed and power, is ideal for large steam volume flows. Steam flows into the turbine via two tangential inlets to equalize thermal loading and blade stress.

Emergency stop valves and control valves are installed in the steam inlet pipes. The steam flows tangentially into the inner casing and then axially to both exhausts. The customized design of the steam path allows exact adjustment to surpass general physical limitations of the last stage blades. Double-end drive is available, if required, e.g. for booster pump drive.

The SST-400 is a single casing steam turbine, providing geared or direct drive to 50 and 60 Hz generators, or to compressors and pumps. The symmetrical casing with horizontal joint flange enables the SST-400 to accept short start-up times and rapid load changes.

The turbine can also accommodate multiple steam extraction / steam induction points as well. The compact design and simple layout of the turbine significantly reduce the cost and time associated with its construction, inspection and maintenance.

The SST-200 is a single casing steam turbine provided in a packaged, skid-mounted configuration. It represents a solution based on long experience with both mechanical and generator drives and is characterized by ease of installation, facilitated by the modular package. The tailor-made, flexible steam turbine exactly fits to the customer needs.

The Siemens SST-200 industrial steam turbine product line is based on the reaction blade technology. The turbine series follows a modular product philosophy, ensuring a high level of performance and reliability. The ability to combine standardized casing modules enable optimal design flexibility. This allows the turbine series to achieve high performance in combination with an optimal cost position.

Our stand-by heating system maintains the turbine at a high temperature during standstills and thereby greatly reduces the start-up time. Keeping the steam turbine generator units warm increases the remaining service time for the most important components, such as the turbine casing and the rotor.

Woodward produces a wide range of standard and custom control platforms that provide complete mechanical control for industrial turbines from start through a full range of output to safe shutdown. Most controls are microprocessor-based with programmable integral application software designed for many types of steam turbine applications.

The 505XT controller is designed to operate single valve, or single extraction/admission industrial steam turbines of all sizes and applications. This steam turbine controller includes specifically designed algorithms and logic to start, stop, control, and protect industrial steam turbines or turboexpanders, driving generators, compressors, pumps, or industrial fans.

The Woodward Peak200 digital control is designed to control steam turbines driving small pumps, compressors & fans based on the proven 505 platform. Features include integrated operator control panel/HMI, communications networks, expandable I/O and more.

The Woodward Peak 150 digital control is designed to control a steam turbine driving a mechanical load. It provides tight control of speed (NEMA D) and includes an input for a 4-20mA remote speed control signal, which can be used for a process-generated input to control the speed setting. Other features include dual speed control dynamics and overspeed trip test capabilities.

The Woodward 505DE is a microprocessor-based control with integral application software that is designed to control double automatic extraction/admission steam turbines. The turbine control architecture is patterned after the popular 505E Single Extraction/Admission Steam Turbine Control. Like the 505E, the 505DE uses configurable software for maximum field flexibility. The control hardware consists of four plug-together modules housed in a rugged metal chassis. The SmartCore module and the analog I/O module contain the I/O required for double extraction turbine control. The main processor and the Ethernet port are located on the Pentium CPU module. The Power Supply module (24 Vdc) is provided to power the entire control assembly. The control also contains 12 relay drivers for external use.

A steam turbine is a machine that extracts thermal energy from pressurized steam and uses it to do mechanical work on a rotating output shaft. Its modern manifestation was invented by Charles Parsons in 1884.[1][2] Fabrication of a modern steam turbine involves advanced metalwork to form high-grade steel alloys into precision parts using technologies that first became available in the 20th century; continued advances in durability and efficiency of steam turbines remains central to the energy economics of the 21st century.

The steam turbine is a form of heat engine that derives much of its improvement in thermodynamic efficiency from the use of multiple stages in the expansion of the steam, which results in a closer approach to the ideal reversible expansion process.

Because the turbine generates rotary motion, it can be coupled to a generator to harness its motion into electricity. Such turbogenerators are the core of thermal power stations which can be fueled by fossil-fuels, nuclear fuels, geothermal, or solar energy. About 85% of all electricity generation in the United States in the year 2014 was by use of steam turbines.[3]

The first device that may be classified as a reaction steam turbine was little more than a toy, the classic Aeolipile, described in the 1st century by Hero of Alexandria in Roman Egypt.[4][5] In 1551, Taqi al-Din in Ottoman Egypt described a steam turbine with the practical application of rotating a spit. Steam turbines were also described by the Italian Giovanni Branca (1629)[6] and John Wilkins in England (1648).[7][8] The devices described by Taqi al-Din and Wilkins are today known as steam jacks. In 1672 an impulse turbine driven car was designed by Ferdinand Verbiest. A more modern version of this car was produced some time in the late 18th century by an unknown German mechanic. In 1775 at Soho James Watt designed a reaction turbine that was put to work there.[9] In 1807 Polikarp Zalesov designed and constructed an impulse turbine, using it for the fire pump operation.[10] In 1827 the Frenchmen Real and Pichon patented and constructed a compound impulse turbine.[11] 2ff7e9595c
