Single-Stage (YR) Steam Turbines

YR steam turbines

Quality, Reliability, and Adaptability

Ebara Elliott Energy single-stage (YR) steam turbines are globally renowned for performance in a wide range of services. They are known for quality, reliability, and adaptability, operating for decades in conditions ranging from humid tropical heat and rainfall to freezing, icy tundra and snowfall. Around the world, YR turbines are on the job driving pumps, compressors, fans, blowers, generators, sugar mill tandems, cane shredders, paper machine lineshafts, and many other applications. 

Our single-valve, single-stage YR turbines feature cost-effective design and superior performance under varying operating conditions. Our multi-YR (MYR) turbines combine the reliability and parts interchangeability of our YR turbine with the power and efficiency of multi-stage turbines. MYR turbines produce more power without additional steam and can be installed in many areas where single-stage steam turbines are currently operating. DYRHH single-stage turbines offer a solution for high back-pressure applications.

Exercise the trip valve without tripping the turbine

pneumatic trip system with partial stroke actuationExercising a trip valve regularly can mean the difference between a turbine tripping when necessary and catastrophic failure. Over time, steam impurities and contaminants can cause boiler scale or rust buildup that could result in the trip valve not working properly when necessary.

Ebara Elliott Energy's pneumatic trip system with partial stroke actuation was awarded a U.S. Patent and is patent pending in several other countries. It is SIL 3 capable, providing a vital safety function for steam turbines. It also gives turbine operators a safe, efficient, and convenient way to exercise the trip valve without interfering with the turbine's operation or its ability to trip if an overspeed event occurs.

front and review view of partial stroke pneumatic trip systemThe partial stroke functionality can be initiated locally or remotely via a distributed control system (DCS). In a matter of seconds, the system completes a partial stroke of the trip valve, and the turbine operators can quickly determine if the trip valve is functioning properly or requires attention.

Our partial stroke pneumatic trip system is available for new equipment or retrofit. For more information, download the Partial Stroke Pneumatic Trip System flyer.

Features & Benefits
  • Verifies trip valve functionality without tripping the turbine
  • Operates independently of the overspeed trip system
  • Features pneumatic cylinder with fail-safe spring closure and fast closing rate
  • 1oo2 and 2oo2 configuration
  • Improves reliability
  • Eliminates spurious trips
  • Withstands excessive vibration
  • Provides cost-effective alternative to a trip & throttle valve
  • Complies with environmental and regulatory requirements

High-Speed Multi-Valve Steam Turbines

high-speed multi-valve steam turbineOutstanding Performance in a Range of Refinery Services

Ebara Elliott Energy's high-speed, high-efficiency multi-valve steam turbine combines the reliability of an impulse style turbine with the efficiency of a reaction style turbine to provide outstanding performance in a range of refinery services. Designed to API 612 standards, the turbine has a small footprint but packs a powerful punch, offering a technical leap forward in speed and efficiency. At typical pressure and temperature operating conditions (typical operating conditions: 600 psig/750°F, high-pressure/high-temperature operating conditions: 1300 psig/ 905°F), the turbine's efficiency is greater than 80 percent.  

The 13-stage, multi-valve turbine serves as a direct drive for compressors in oil and gas-related services including hydrocracking, hydrotreating, catalytic reforming, alkylation, refrigeration, gas boosting, and coking. Its high-speed condensing design eliminates the need for a separate gear box, greatly reducing the amount of mineral oil, cooling water, and steam required for high-efficiency operation. The turbine's high-speed capabilities allow for smaller compressor frame sizes with fewer stages for a smaller overall footprint.  

Features & Benefits

  • Direct drive - eliminates the need for a separate gear box
  • High performance - greater than 80% efficiency
  • Operational efficiency - 12 to 14% steam savings
  • Speed matches the compressor, allowing for a smaller compressor frame size with reduced number of stages
  • Compact casing size - 20% in space savings
  • Lower operating cost - less mineral oil and cooling water required
  • Reduced maintenance - fewer spare parts required
