Claims

[Claims for Utility Model Registration] 1. A furnace having a rectangular cross section has several sets of burners arranged vertically in several stages at the same height at the center of the four peripheral walls of the furnace, and each of these burners is and a tanzenshalf earring furnace characterized by having an injection angle that injects air and the like at an angle of 5° to 10° in the same direction from the perpendicular direction to the related peripheral wall surface. 2. In the Tanzenshalf earring furnace according to claim 1, there is a burner on the injection direction side at an intermediate height position of each set of burners in which inlets for overfire air blown in for two-stage combustion are arranged vertically. A Tanzenshalf earring furnace characterized by being placed in contact with.
