Abstract
A heating iron utilizing the heat obtained through complete catalytic combustion of liquefied gas comprises a catalyst combustion chamber having an inner gas flow channel confined therein and in direct connection with a gas mixture generating means and a pre-heating zone disposed to the outer circumferential surface of the catalyst combustion chamber, in which the pre-heating zone is heated upon start of the catalytic combustion to heat the catalyst layer in the catalyst combustion chamber to a temperature sufficient for starting the catalytic oxidizing reaction in a flameless manner.
Claims5
An iron for heating a workpiece comprising:
- a nozzle for jetting out a combustible gas from a liquefied gas reservoir;
- a gas mixture generating means at the exit of said nozzle for drawing air to mix with said combustible gas to form a mixture;
- a catalyst combustion chamber downstream of said generating means having a gas flow channel extending therethrough with a catalyst layer deposited on the channel wall and a portion of the channel wall forming a pre-heating zone;
- means for directly and flamelessly heating the outer side of said chamber to heat said pre-heating zone to ignite said mixture;
- and
- a tip member at least partially surrounding the catalyst chamber for conducting the heat from said chamber to a workpiece.
