Zusammenfassung:A combustion burner refractory material retention system is provided. The system may include a tubular enclosure having a first section and a second section, 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 may be disposed within the tubular enclosure second section. A first support layer may be disposed on a surface of the refractory material body, and at least one outer support 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.
