PROBLEM TO BE SOLVED: To provide an air heat burner capable of properly adjusting the flow rate of the air with residual oxygen to be guided to an air blowout cylinder while keeping a stable combustion. SOLUTION: This air heat burner 1 has a fuel supplying header 2 arranged within a duct 6 to blow out fuel Fu, and the air blowout cylinder 3 for blowing out the air Ai with residual oxygen. A rotatable first profile plate 4 is provided between the duct 6 and the air heat burner 1. A bypass clearance 61 for bypassing part of the air Ai to the downstream side of the duct 6 is provided between a rotating fulcrum 41 and the air heat burner 1. The first profile plate 4 is constituted so as to adjust the flow rate of the air Ai to be guided to the air blowout cylinder 3 by rotating its tip 42 toward the upstream side. COPYRIGHT: (C)2004,JPO
