SEALING SOLUTION & HIGHLIGHT

Scenic provides a sealing solution featuring the newest technology of the non-contact dry gas seal STG170™, for the steam turbine in the power and energy industry. By replacing the old multi-segment ring used by customers, less downtime for maintenance and reduced steam leakage are achieved.

• High reliability- Non-contact dry gas seal (zero abrasion).
• Utilizes the steam from the turbine as a power source for STG170™, extra gas support system is unnecessary.

Gas seal for steam turbine STG170™

WORKING CONDITION

• Industry/Equipment: Power & Energy/ Steam Turbine
• Temperature: 240°C
• Pressure: 13kg/cm²
• Rotating Speed: 3560RPM
• Power: 27kW
• Lubrication: Bearing Oil
• Sealing Type (Before): Multi-Segment Ring Set
• Sealing Type (After): Non-Contact Dry Gas Seal STG170™

BEFORE

• Multi-segment ring was used as the sealing component of the steam turbine.
• Unable to prevent leakage of high-pressure steam.
• Extended operation will cause damage to the carbon seal ring and turbine shaft.
• The damaged turbine shaft enlarges the gap and increases the steam leakage.
• The oil lubricant is susceptible to contamination from steam leakage, leading to degradation and turbine bearing damage.
• Massive leakage leads to widespread corrosion of the equipment and energy waste.

AFTER

• Near zero leakage.
• Avoid the emulsification of oil lubricant in the turbine bearing caused by thermal shock.
• Reduce drive power consumption, increase energy efficiency.
• No damages to the steam turbine shaft.
• Decrease the probability of bearing damage and lubricating failure due to steam leakage.
• Cost savings.
• Long service life.
