PROBLEM TO BE SOLVED: To provide a heating device capable of increasing the amount of radiant heat for radiant heating. [Solution] A frame 1 formed by a lower plate 2, a side plate 3 that covers the back and left and right side surfaces, a front plate 4 on the lower front surface, and a top plate 5 on the upper surface, and a cover plate that divides the interior of the frame 1 into upper and lower parts. In a petroleum stove comprising: 15, a combustion cylinder placed on an upper part of the cover plate; and a radiation plate 14 provided so as to surround the combustion cylinder 6 and integrated with the cover plate. The radiant plate vent 27 is formed at the lower end of the radiant plate 14 just behind the combustion cylinder 6, and the rear vent 28 is formed at the back of the side plate 3 just behind the radiant plate 27. Even if it falls down forward or backward due to such reasons, the air smoothly flows over the upper portion of the core guide cylinder 25 where the combustion cylinder 6 is disengaged and the upper part is exposed, and even if a flame remains on the wick 12, the fire is extinguished. , Fire extinguishing time can be shortened.
