The heat generation device includes a cordierite based ceramic body on which a platinum based oxidation catalyst is coated. An initial ignition device is provided to cause an initial burning of the fuel supplied to thereto for heating the catalyst to the working temperature thereof. Once reaching the working temperature, the catalyst itself maintains the oxidation or burning of the fuel in a flameless manner and the heated air flow is continuously supplied until the fuel supply is cut off and the fan turned off.
