ブ。 Inside the outer tube whose tip is closed, an inner tube having an outer diameter smaller than the inner diameter of the outer tube is placed approximately concentrically so that the tip of the inner tube faces the closed tip of the outer tube with a gap. A burner is installed in the gap between the outer tube and the inner tube at the rear end, and the high-temperature combustion gas generated by the burner heats the outer tube through the gap between the outer tube and the inner tube, and then is exhausted through the inner tube. A single-end type radiant tube that is characterized by the following.
