Abstract
Insulating members are provided for use in nozzles of elevated temperature process vessels employing a structural metal shell (), an insulating refractory lining () and a corrosion-resistant membrane () lining between the structural shell and refractory lining. The insulating members comprise pre-formed insulating sleeves and inserts and are made of a thermally insulating material having sufficient thickness and sufficiently low thermal conductivity such that, when the sleeve or insert is heated by the process temperature during operation of the vessel, the thermal energy transmitted through the sleeve or insert to the membrane is insufficient to raise the temperature of the membrane above a target temperature. The most preferred thermally insulating materials are fluoropolymers such as poly(tetrafluoroethylene) flouropolymer resins.
