PURPOSE:To provide a burner plate made of fiber ceramics, by which uniform combustion flames can be held even in high temperature above 900 deg.C. CONSTITUTION:Projections 2 on the surface of a plate 1, made of fiber ceramics of which framework is refractory inorganic fiber, are in the shape of a hexagonal pyramid, forming a continuum on the surface of a burner plate, and consisting of a combustion surface. A burner port 3a piercing through the burner plate from the back of it is provided to the center of each side of a hexagon on the base of each projection 2. A burner port 3b is provided to the top of each projection 2 also in the same manner. One side of the base of a projection 2 is 2mm.-3mm., while its height is 2mm.-3mm.. The diameters of both burner ports 3a and 3b are 0.8mm.-1.6mm.. Each size is adjustable in accordance with the kind of fuel gas and the condition of combustion. By providing burner ports not only in the center of each side of the base of an projection in the shape of a hexagonal pyramid but also to the top of each projection as mentioned above, combustion on the burner plate can be stabilized, and the burner plate can hold uniform combustion flames in high temperature. |
