Gas burner and a gas powered heating device

Abstract

A soldering iron (,) comprises a soldering head (,) connected to a handle (,). A cylindrical catalytic element (,) located in a combustion chamber (,) converts gas to heat for heating a soldering tip (,). An electrode (,) located within the catalytic element (,) initially ignites a fuel gas/air mixture to burn in a flame (,) within the catalytic element (,) for raising the temperature of a downstream portion (,) of the catalytic element (,) to its ignition temperature. Heat from the downstream portion (,) raises an upstream portion (,) of the catalytic element (,) upstream of the flame (,) to its ignition temperature, which then commences to convert the fuel gas/air mixture to heat. This starves the flame (,) of fuel gas/air mixture, thus extinguishing the flame (,) so that the catalytic element (,) continues to convert fuel gas/air mixture to heat in a catalytic reaction.
