HRSG Inlet Sealing Solutions for High Movement and Reliability

Challenge at HRSG Inlets

The inlet points of Heat Recovery Steam Generators (HRSGs) are among the most demanding expansion zones due to significant movement requirements. At gas turbine (GT) exhaust temperatures, large movements occur in the floor and side wall areas of front modules within a limited cross-section. This necessitates a reliable and durable sealing solution to maintain operational integrity.

Traditional metal expansion joints are challenging to replace, while leaking gland seals or mechanical seals increase maintenance needs and negatively impact the enclosure and surrounding equipment. These issues make such solutions costly and unreliable.

Solution: Flexible and Reliable Fabric Sealing

Bundletec has developed innovative fabric sealing solutions tailored to integrate seamlessly with existing HRSG systems. These solutions enable regional patching, repairs, and part replacements, significantly reducing downtime and operational interruptions.

The engineered fabric structures maintain their shape without creasing or folding across all movements, delivering exceptional performance in high-cycle operations. Key features include:

Multi-layered construction: Ensures gas-tight sealing and protection against stress.
High-temperature-resistant membranes: Withstands extreme GT exhaust conditions.
Flexible design: Accommodates large movements while maintaining structural integrity.

These fabric seals provide a cost-effective, reliable alternative to traditional solutions, enhancing system longevity and operational efficiency.
