Abstract

PURPOSE:To pevent a medium from leaking into an air chamber, by coupling a truncated-cone-shaped porous swirling bottom plate to the peripheral part of conical non-perforated injection bottom plate and making the vertical angle of the swirling bottom plate larger than that of the injection bottom plate. CONSTITUTION:A furnace 1 with a swirling jet layer has the conical non-perforated injection bottom plate 3a, which has a vertical angle alpha and is coupled to a jet feed pipe 2. The truncated-cone-shaped porous swirling bottom plate 3b is coupled to the peripheral part of the injection bottom plate 3a and has a vertical angle beta larger than the former alpha.
