During heating up, cooling down and even in operation, the many steam and water tubes collecting here move in opposing directions due to thermal expansion.
During heating up, cooling down and even in operation, the many steam and water tubes collecting here move in opposing directions due to thermal expansion. A durable metallic sealing has proven difficult to provide, as steel is very inelastic. Due to the differences in pressure, fluegas carrying flyash will enter through leaks into the dead space from the combustion chamber. The flyash will settle in the dead space and the flue gas will continue either to the second draft of the boiler or further out into the boilerhouse.
Hasle Isomax Isomembrane® technology was developed to deal with these problems. Isomembrane® is a flexible, elastic and ashtight sealing composed of proprietary materials. Isomembrane® is considered the most advanced and efficient way to seal dead air spaces and can be applied to existing boilers, or new construction. Isomembrane® has been installed throughout Europe with great success and is now available in the United States from High Temperature Technologies.
High Temperature Technolgies is the exclusive North American licensed applicator of Isomembrane®. With the support of Hassle Isoma, HTT designs and sinstall Isomembrane® throughout the United States utilizing only certified Isomembrane® technichians.
Isomembrane® has proven its effectiveness for more than a decade in Europe, in powerplants ranging in capacity from 9Mw to 2,200 Mw. Our experience shows a lifetime of 8 to 12 years in an undisturbed environment.
