Abstract:
1. A combination of a gas catalytic combustion element and a thermal mass, the gas catalytic combustion element being for converting fuel gas to heat for heating a body member of a device, the thermal mass being in heat conducting engagement with a portion of the gas catalytic combustion element, so that heat is transferred to the thermal mass from the gas catalytic combustion element when the gas catalytic combustion element is converting fuel gas to heat, and heat is transferred from the thermal mass to the said portion of the gas catalytic combustion element adjacent the thermal mass when the gas catalytic combustion element is not converting fuel gas to heat, the thermal mass being located so that the thermal mass is not in direct heat conducting engagement with the body member with which the combination is to be used, the thermal mass being of size adapted to store sufficient heat for maintaining the said portion of the gas catalytic combustion element adjacent the thermal mass at or above the ignition temperature thereof during periods of fuel gas interruption to the gas catalytic combustion element, so that when the fuel gas supply is restored to the gas catalytic combustion element, the said portion of the gas catalytic combustion element adjacent the thermal mass commences to convert the fuel gas to heat by catalytic action for raising the temperature of the remainder of the gas catalytic combustion element to its ignition temperature.
