It should be understood that there are many variables to this desCTipiion. Burners may be located In the side walls or roof of the radiant section. Insulation may be reftactory brick, ceramic fibers, or a mineral wool blanket. The produa may flow into the convection section tubes, exit that seaion through crossover piping, and flow through the radiant seaion. Multiple furnaces may be tied to one common sack by breeching.
