PROBLEM TO BE SOLVED: To improve combustion output of a rotary vaporization type burner usable in a grain dryer or the like. SOLUTION: The rotary vaporization type burner is provided with a burning tube 28 provided in a front face side of a casing 27, a combustion board 36 with gas jet holes 36a, etc. provided in a front face outer circumference side of the burning tube 28, and a vaporizing tube 32 provided in a center part of the burning tube 28 and turned by a burner vaporizing tube motor M6. Atomized fuel migrating on an inner circumference face of the vaporizing tube 32 by radiation heat of combustion flame of the combustion board 36 is gasified, guided to a rear face of the combustion board 36, jetted out through the gas jet holes 36a, etc., and burned as blue flame. A motor rotational speed control means 51 is provided for turning the burner vaporizing tube motor M6 for vaporizing tube 32 turning at 3600 revolutions per minute or more, and turning the vaporizing tube 32 at 3600 revolutions per minute or more.
