PURPOSE:To provide a combustion device with the wide control range of combustion rate by a structure wherein an air regulator, which changes the opening area of an air passage formed within a wick inner tube by interlinking with the lifting device of a wick, is provided. CONSTITUTION:The titled combustion device is equipped with a wick lifter 22 to lift and lower a wick 3, the lifting device 23 of the wick 3 and an air regulator 24, which interlinks with the wick lifting device 23 by transmitting the regulating action of the air with an actuating shaft 25. The air regulator 24 locates at the bottom of a wick inner tube 1 so as to change the opening area of an air passage 26 within the wick inner tube 1. When high combustion intensity is intended, the air regulator 24 is in open state (as indicated with the solid line) or the air passage 26 is widely open and accordingly enough air is supplied through an air lead-in port 27 in the inner flame tube 6. On the other hand, when low combustion intensity is intended, the flame which fills a primary combustion chamber 8 at high combustion intensity falls down in the primary combustion chamber 8, and accordingly the upper portion of a red heat part is cooled down, and consequently the phenomenon to generate a large amount of CO can be suppressed, and the control range of combustion range can be widened.
