ABSTRACT:
A heat processing device using a liquefied gas comprises a nozzle for jetting a liquefied gas, a gas mixture generating member disposed at the exit of the nozzle for sucking external air through an external air intake port under the ejector effect of the gas jetted out from the nozzle to form a gas mixture, a fire nozzle member for jetting out the thus formed gas mixture to take place flaming combustion, and an air flow control member for controlling the flow rate of air flowing through the air intake port into the gas mixture generating member. The heat processing device further comprises an iron tip member having a combustion catalyst detachably disposed near the top end of the fire nozzle, in which the air intake port in the fully opened state is once closed fully and then fully opened again by the operation of the air flow rate control member interlocking with the operation of the shutter member for closing/opening the space between the fire nozzle and the combustion catalyst.
