Abstract

Liner device, adapted to be mounted between a burner box and a tube interface plate of a furnace. The liner device includes a base section, one or more tube sections, and one or more angle fasteners. The base section includes a shielding layer formed from a first flexible mesh of flame-resistant fibers, the shielding layer defining a first surface that is configured to face the burner box, a second surface opposite to the first surface, and a medial region with a through-hole forming a passageway through the shielding layer. The tube section is composed essentially of a second flexible mesh of flame-resistant fibers formed into a tubular shape that defines an internal channel around a nominal axis. A proximal end of the tube section is positioned at the base section, such that the channel opens into the through-hole and that the tube section projects from the second surface and in a direction faced by the second surface. The angle fastener has a base portion that is positioned along and fixed to the second surface of the shielding layer. The angle fastener further has a leg portion that projects towards the second direction and is positioned along and fixed to an outer surface of the tube section at or near the proximal end thereof.
