Abstract
A lightweight burner block assembly includes (a) a relatively thick exterior shell, the exterior shell comprising a refractory material including fibrous alumina and silica and having an internal bore; and (b) a relatively thin, erosion resistant liner inserted into the internal bore, the liner comprising (i) a fabric matrix of woven ceramic fibers having insulating properties and thermal shock resistance properties and (ii) silicon carbide particles supported by and coating the fabric matrix.
Claims14
A multi-layer article having thermal insulating properties, thermal shock resistance properties and erosion resistance properties, said multi-layer article comprising:
- a relatively thick exterior layer composed of relatively lightweight, internally porous, thermal shock resistant, relatively erosive, refractory material comprising comminuted fibrous alumina and silica;
- and a relatively thin, erosion resistant, corrosion resistant and thermal shock resistant interior layer lining said exterior layer and comprising (a) a fabric matrix of woven ceramic fibers having insulating and thermal shock resistant properties and (b) silicon carbide particles supported by and coating said matrix.
A burner block assembly comprising:
- a relatively thick, exterior shell having an internal bore;
- and a relatively thin, erosion resistant, corrosion resistant and thermal shock resistant liner for said internal bore;
- said exterior shell being composed of a relatively light weight, internally porous, thermal shock resistant, relatively erosive, refractory material comprising comminuted fibrous alumina and silica;
- said liner comprising (a) a fabric matrix of woven ceramic fibers having insulating and thermal shock resistant properties and (b) silicon carbide particles supported by and coating said matrix.
