Abstract
A burner throat is defined by a cage of tubes and is lined by fitting refractory tiles. A plurality of retaining means each having two joined parts, the outer part abutting the tubes and the inner part exerting an abutting force radially inwards on the tiles to retain them in position. In use the abutting force on the tiles can be varied to suit the design characteristics and environment, by varying the exposed length of a pin which threadedly mates in a complementary bore in each of the two parts. To further secure the tiles, a dowel is provided to mate in complementary bores formed in an adjacent side of abutting tiles.
Claims7
A generally arcuately shaped body comprising a generally arcuate cage of tubes in which access to the cold side thereof is restricted;
- an inner lining of fitting refractory tiles laid in circular courses along the axis of the arcuate cage of tubes;
- each course having a plurality of joining means between abutting tile edges to prevent relative movement of said tile edges;
- the arcuately shaped body having a plurality of non-permanently fixed and adjustable retaining means located between the tubes and tiles so as to exert an abutting force radially inwards on the tiles and thereby retain them in position.
