The invention relates to a heat accumulating vaporization burner. The invention adopts the technical scheme that: the burner comprises a preheating pipe, a main body, a heating device, a vent pipe I, an injection nozzle, a vent pipe II and a gas collection chamber; the main body is annular, the interior of the main body is provided with a closed vaporization chamber, and the area encircled by theinner surface of the main body forms a combustion chamber; and the outer surface of the main body is provided with the heating device, the preheating pipe is arranged at the upper end of the main body and communicated with the vaporization chamber, one end of the vent pipe I passes through the main body and is inserted into the vaporization chamber, the other end of the vent pipe I is communicated with the gas collection chamber, one end of the vent pipe II is communicated with the gas collection chamber, the other end of the vent pipe II is connected with the injection nozzle, and the injection nozzle is connected with the main body and extends into the combustion chamber. The injection nozzle is in a shape that the shape of an internal through hole is of two coaxial round tables and thesmall end faces of the two round tables are superposed. The burner has full combustion and high combustion temperature, saves energy and reduces the cost.
