Title: BURNER TILE, BURNER, AND FURNACE
Abstract:
Provided is a burner tile which has favorable fire resistance, heat resistance, wind corrosion resistance, and thermal shock resistance. A burner tile (1E) is formed from an inorganic fiber molded body and has a burner-use main hole (3E), wherein the inner circumferential surface of the main hole (3E) is constituted by an inner covering part (120) made from a laminate of inorganic fiber plate bodies (121, 122). An outer covering part (130) is configured by enclosing the outer circumference of the inner covering part (120) with an inorganic fiber molded body. A portion along the inner circumferential surface of the main hole (3E) has high bulk density. High bulk density is achieved by adhering a large amount of an inorganic binder to the inorganic fiber forming the area near the inner circumferential surface.
