Steam Turbine Seal Optimization​

EthosEnergy is a pioneer in steam turbine seal upgrades. Make the SMART choice, during your next outage, upgrade to customized advanced seals to increase turbine efficiency and reliability, lower emissions and maximize your investment.

Steam leakage caused by increased seal clearances throughout the steam path prevents steam turbines from running at their optimum performance levels. By reducing these clearances and maximizing the effectiveness of steam turbine sealing, significant operational improvements can be realized. Benefits include reduced fuel consumption and greenhouse gas emissions, as well as improved efficiency, generation capability, availability and reliability.

What can we do to help?

Steam turbines, especially older ones, are not running at optimal levels due to degradation in the steam path, including the sealing components. EthosEnergy SMART Seals™ are a cost-effective way to upgrade performance without major capital expenditures or modifications to the unit.

Each SMART Seal™ package is custom designed based on a review of your steam turbine design, MW output, and operating profile. SMART Seal™ upgrades may include some, or all of the following upgraded components which EthosEnergy has established in the market: custom fit conventional packing and tip seals, reduced clearance tip seals, retractable packing rings, retractable brush packing rings, brush tip seals, articulated snout rings/inlet seals, and upgraded horizontal joint bolting. With over 1,000 installations worldwide, EthosEnergy has proven the value of upgrading turbine seals.

Benefits include reduced fuel consumption and greenhouse gas emissions, as well as improved efficiency, generation capability, availability and reliability.
