ABSTRACT:
An internal-combustion type iron has a nozzle provided in a grip portion so as to spray a jet of gas supplied from a liquified-gas tank into a hollow barrel. The hollow barrel has a base portion fitted to the grip portion and communicating with the nozzle. An air hole is provided in the base portion of the barrel so that the outside air may be sucked into and be mixed with the gas from the nozzle. A gas flow control body is disposed in the center of a hollow portion of the barrel generates a stagnant vortex flow in the flow of the mixture of the gas and air. A mixing chamber is provided in the hollow portion of the barrel between the air hole and the gas flow control body. The mixing chamber has a length sufficient for the required mixing of the gas with air and for stabilization of flow velocity. A heating chamber is provided in the hollow portion of the barrel between the gas flow control body and an exhaust port provided at the tip of the barrel. The heating chamber has a length sufficient for the required heating of the barrel by the combustion gas. The stagnant vortex flow of the gas mixture is generated at a predetermined distance from the nozzle by the gas flow control body and is ignited with the flame being maintained at this point.
