ABSTRACT:
A hot blow generating device utilizing a liquefied gas as a heat source comprises fuel gas jetting means, air/fuel gas mixture forming means by the ejector effect of the jetting fuel gas, catalytic combustion means formed with a plurality of linear axial gas flow channels, hot blow discharging means, and means for forcively supplying an air stream at least partially to said air/fuel gas mixture forming means depending on the combustion temperature in the device. A hot blow at a great flow rate can be obtained in a structure small in the size and reduced in the weight, safely and conveniently.
