Single-Valve Steam Turbine Upgrades Available from Ebara Elliott Energy
Pneumatic Trip System
A pneumatic trip system upgrade (with or without partial stroke actuation) maximizes trip system reliability. The partial stroke option enables trip system testing while the turbine is in operation.
Microswitch
A microswitch upgrade provides a remote indication of the trip valve position (Open/Closed) for improved reliability.
Electronic Govemor and Actuator
Upgrade to an electronic governor and actuator for more precise speed control, improved reliability, and increased safety.
Electronic Overspeed Trip Device
Upgrade to an electronic overspeed trip device to monitor the rotational speed of the rotor for improved reliability and safety. The turbine will trip if the speed increases above the set limit.
Pneumatic Hand Valve
Upgrade to a pneumatic hand valve (overload valve) to control steam flow into the turbine casing for improved efficiency. Recommended for turbines operating at variable conditions.
Pressure Lubrication System
Gland Evacuation System
A gland evacuation system upgrade provides improved management of gland leakage and increases reliability.
Nozzle Ring
Nozzle rings are specifically designed for each application to maximize the potential of the steam flow for optimal performance or to adjust power capacity.
Tip Seal
Tip seal upgrades prevent the loss of steam across the tips of the rotor blades for improved reliability.
Bearing Isolators (EBIs)
Upgrade to Ebara Elliott Energy Bearing Isolators (EBIs) to maximize oil purity and bearing life for improved reliability.
Instrumentation
Instrumentation upgrades facilitate early problem detection and aid in maintenance planning for enhanced operational performance.
Gland Packing
Upgrade to brush ring seals to reduce steam leakage along the rotor shaft and prevent air from entering the turbine casing for improved reliability and efficiency.
Insulation Blankets
Insulation blankets reduce noise levels and protect operators from the dangerously hot turbine surface for improved safety.
Remote Trip Solenoid
Upgrade to a remote trip solenoid to initiate a trip function from an electronic device or control room for improved safety.
Brush Ring Seals
Ebara Elliott Energy's brush ring seals provide sealing stablility for improved reliability and increased operational efficiency. They minimize gland leakage and reduce the frequency of seal replacement.
