PURPOSE:To carry out adjustment of the volume of air to each flow channel without generating vibration sounds by rotating a plate provided with a through-holes and matching those through-holes to the throughholes in a fixed plate which communicate with respective air flow channels in the main body of a cylindrical burner and sending air through the matched through-holes and constituting so as to pressure-weld a movable plate to the fixed plate. CONSTITUTION:A damper C for change-over of air flow channel is provided at the connecting section of the main body of a cylindrical burner and an air sending cylinder 12, and at the rear of the main body of the cylindrical burner a disc shaped fixed plate 40 incorporated in the main body is provided with fan-shaped through-holes 4a-40c 180 deg. apart and symmetrically which communicate respectively with a primary air flow guide cylinder 28, secondary air flow channel 31, and tertiary air flow channel 33, and a movable plate 41 is provided with through-holes of an irregular shape 41a-41c 180 deg. apart and symmetrically, and through- holes 4la and 41b are provided on the same radius, and the through-hole 4lc is provided in the circumferential direction which is perpendicular to those throughholes, and between the through-holes 41b and 41c a plurality of auxiliary through-holes 41d of small circle shape are provided. And, in the connecting hole 41g at the central section of a movable plate 41a a boss 55 to which the output shaft 54 of a rotating motor 42 is installed is inserted and the boss has a spring 59 attached to it and it energizes the movable plate to the side of the fixed plate.
