Claims

[Scope of utility model registration request]

(1) A heat-resistant inner cylinder is installed within a heat-resistant tube, an annular combustion chamber is formed between the tube and the inner cylinder, and a plurality of gas blowing holes are bored on the circumferential surface of the inner cylinder. and a radiant tube that is provided with a first flow path that communicates with the combustion chamber from the outside and a second flow path that communicates with the combustion chamber from the outside through the inner cylinder, the gas blowout hole, and the combustion chamber. A radiant tube characterized in that the gas blow-off holes are formed obliquely to a straight line extending radially from the axis of the inner cylinder.

(2) Utility Model Registration The radiant tube according to claim 1, wherein the tube and the inner cylinder are made of high-strength ceramics.

(3) Utility Model Registration The radiant tube according to claim 1 or 2, wherein the gas blowing hole of the inner cylinder is smaller on the base side and larger on the tip side of the inner cylinder.
