Anchoring system for non-shaped refractory material on a tubular wall of a boiler comprises anchoring pieces with a hollow part covering support components welded to the flanges of the boiler tubes

摘要

An anchoring system for a non-shaped refractory material (16) on a boiler wall made up of tubes (11) arranged in parallel and connected by lateral flanges (12) includes some metallic support components (20) welded onto the flanges. Each support component is covered by a hollow part (22) of an anchoring piece (21) of ceramic material which rests on the flanges to which it is welded. The anchoring piece is integral with the support component joined by a chemically setting refractory mixture which fills the hollow part. The anchoring pieces are in a counter relief form and flow towards the refractory material turned towards the interior of the boiler.
