Abstract: 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.

Abstract: Dust Da containing zinc and iron is charged in a rotative cylindrical kiln base body 11 of an indirect-heating rotary kiln 10 and is subjected to heat treatment in the kiln base body so that zinc contained in the dust is volatilized. The volatilized zinc is guided to a treatment device 30 through an exhaust pipe 31 disposed at a discharge part 16 of the rotary kiln and is recovered. A residue Db resulting from the treatment in the kiln base body is transferred from a residue outlet 16b disposed at the discharge part 16 of the rotary kiln to a burner device 40, in which the residue is combusted and heated.
