Field Problem / Customer Requirement
Inlet points in HRSG boilers are among the most challenging expansion points due to their extensive movement requirements. Particularly at GT exhaust temperatures, large movements occur within a limited cross-section in the floor and sidewall areas of the front modules. This makes a reliable and durable sealing solution critical.
BundleTec Innovation and Engineering Solution
The difficulties in replacing traditional metal expansion joints and leaking gland seals or mechanical seals both increase the need for regular maintenance and cause negative impacts on the casing and surrounding equipment. This situation makes them an expensive and unreliable solution.
As BundleTec, we have developed innovative fabric sealing solutions compatible with existing systems to address these problems. These solutions allow for localized patching, repair, and part replacement. Thus, downtime or outages are minimized.
The formed fabric structures maintain their shape without buckling or folding throughout all movements, offering excellent performance in high-cycle operations. Multi-layered structures and high-temperature resistant membranes ensure gas tightness and provide protection against stress.
