To provide a fire breathing cylinder in which an air amount blown out of a fire breathing port is increased.

This invention relates to a fire breathing cylinder 11 used for supplying air to material to be ignited to make fire at the material, in which the fire breathing cylinder 11 is a cylinder having a prescribed length, and has a breathing port 12 at one end and a blowing-out port 13 at the other end. A location along an inner peripheral surface 21 inside the cylinder measured from the blowing-out port 13 by a prescribed length is provided with a knot part 14 for blocking a flow of air. The central part of the knot part 14 is formed with small holes 15, and a location near the blowing-out port 13 near the knot part 14 is formed with an air inlet hole 16 for use in flowing air from outside the cylinder.
