REFRACTORY MATERIAL RETENTION DEVICE

摘要

A combustion burner refractory material retention system is provided. The system may include a tubular enclosure (28) having a first section (42) and a second section (44), wherein the first section has an internal cross- sectional area that is less than an internal cross-sectional area of the second section. A refractory material body (32) may be disposed within the tubular enclosure second section. A first support layer (34) may be disposed on a surface of the refractory material body, and at least one outer support (36) layer may be disposed between the refractory material body and a wall of the tubular enclosure second section. The first support layer may form an insulating barrier between the refractory material body and the outer support layer, and a cross-sectional area of the combined refractory material body and first support layer may be at least as large as the internal cross-sectional area of the tubular enclosure first section.
