Claims (1)

[Claims for Utility Model Registration] 1. A gas injection member that injects liquefied gas in a gas tank as fuel gas; and a gas injection member that is provided on the outlet side of the gas injection member and that uses the ejector action of the gas injected from the gas injection member to vent the outside air. a cylindrical mixed gas generation member that sucks air from an inlet to generate a mixed gas; a crater member that is provided at the tip of the mixed gas generation member and injects the mixed gas into a cylindrical flaming combustion cylinder; ; piezoelectric ignition means for igniting the mixed gas in the flaming combustion tube by operating an ignition button; and a built-in combustion catalyst disposed at the tip side of the flaming combustion tube for flameless combustion of the mixed gas through an oxidation reaction. A tip member; formed in at least one of the flaming combustion tube, the iron tip member, or between the flaming combustion tube and the iron tip member, and being open at least immediately before ignition. a gas exhaust mechanism that directly discharges a part of the gas in the flame combustion cylinder to the outside without passing through the combustion catalyst; movably provided on the outer surface of the mixed gas generation member;
Immediately before ignition, the opening area of the outside air intake port is made small to generate an air-deficient mixed gas, and after flaming combustion, the opening area of the outside air intake port is reduced to zero or extremely increased to extinguish the flame, and then A liquefied gas characterized by comprising: an air volume adjustment mechanism that returns the opening area of the outside air intake to an optimal size after the flame has been extinguished; and an interlocking mechanism that interlocks the air volume adjustment mechanism and the ignition button. Thermal processing equipment used. 2. The gas exhaust mechanism is characterized by comprising a gas exhaust port provided on the peripheral surface of the tip of the flaming combustion tube, and a shutter provided on the outer periphery of the flaming combustion tube for opening and closing the gas exhaust port. A thermal processing apparatus using liquefied gas according to claim 1 of the utility model registration claim. 3. Utility model registration claim 1 or 2, characterized in that the air amount adjustment mechanism includes an adjustment member that moves the outer surface of the mixed gas generation member to adjust the opening area of the outside air intake port. A thermal processing device using the liquefied gas described above. 4. The interlocking mechanism has a band-shaped connecting member whose base end is fixed to the ignition button, whose tip is pulled out to the outer surface of the mixed gas generating member, and whose tip operates in the axial direction of the mixed gas generating member when the ignition button is operated. A thermal processing apparatus using liquefied gas according to claim 1, 2, or 3 of the utility model registration claim.
