Figure 3. Common fiber tile shapes. Flanges may be round or square.
Figure 2B. Fiber board shield for all flat flame type burner tile installations.
1 Port clearance hole--at least 1" larger in diameter than tile port diameter.
2 Fiber board shield can be round or square--equal to at least twice tile diameter or width.
Figure 4. Methods of securing fiber tile shapes to burners and furnace walls.
3 Shield hole must be cut to provide snug fit. Coat all edges and inner face with high temperature, air setting refractory cement. 4 Flat flame burner tile face must never be recessed into furnace wall. It must be flush or less than ½" extended into furnace beyond adjacent ceramic fiber board. Con- figurations are available with proper mounting flange placement to accomplish this (see "Z" dimension note in Figure 1). If burner tiles do not have variable "Z" dimen- sion option, burner must be recessed into or extended out from furnace wall to maintain hot face position requirement (see Supplement DF-M1, Figure 1B).
NOTE: 1. Using high temperature, air setting refractory cement, coat all surfaces of fiber tile shape that are in contact with burner, shell, or furnace lining. Fill all voids. 2. Fiber tile surfaces can be pierced and/or compressed to accommodate burner mounting bolt heads and anchor- ing protrusions. 3. If possible, wrap fiber tile with blanket insulation as shown in Figure 1.
