BURNER TILE, BURNER, AND FURNACE

摘要

Provided is a burner tile that has good fire resistance, good heat resistance, good erosion resistance, and good thermal shock resistance. A burner tile 1E includes a molded inorganic fiber product and has a burner main hole 3E. The burner tile 1E includes an inner layer 120 including a combination of inorganic fiber rods 121 and 122 such that the inner layer 120 defines an inner circumferential surface of the main hole 3E, and an outer layer 130 formed by surrounding an outer circumferential surface of the inner layer 120 with the molded inorganic fiber product. Part of the burner tile 1E extending along the inner circumferential surface of the main hole 3E has a high bulk density achieved by highly concentrating an inorganic binder in the inorganic fiber in part including the inner circumferential surface.

主权项

1: A burner tile including a molded inorganic fiber product and having a burner main hole extending therethrough in a furnace interior-exterior direction, the burner tile comprising:
an inner layer surrounding the main hole and an outer layer surrounding an outer circumferential surface of the inner layer, the inner layer and the outer layer being included in at least part of the burner tile adjacent to a furnace interior, the inner layer including inorganic fiber rods arranged and combined such that end surfaces of the rods extend substantially radially from the main hole, the outer layer including an inorganic fiber blanket wrapped several turns around the outer circumferential surface of the inner layer, wherein the burner tile includes an outer part formed by rolling a plurality of superposed inorganic fiber blankets having different bulk densities.
