Abstract
The invention relates to a heating device (100) employing catalytic combustion of gas, especially of petroleum gases, comprising: a flat combustion enclosure (110) delimited by two parallel large plane walls (111, 112), at least one of which is a heater plate made of a metallic material, the said combustion enclosure (110) being provided with at least one gas inlet (130a, 132a, 132b, 134a) and one outlet (111a, 111b), a gas circulation circuit, devised inside the said combustion enclosure (110) between each gas inlet and each outlet, the gas circulation circuit passing through at least one catalytic contact surface (121a, 122a, 123a, 124a). According to the invention, the gas circulation circuit is defined by at least one catalytic support partition (121, 122, 123, 124), a longitudinal face of which constitutes the catalytic contact surface, the said partition extending perpendicularly to the heater plate, over practically the whole height of the said combustion enclosure so that the combustion front (121b, 122b, 123b, 124b) situated on the said catalytic support partition is flush with the heater plate, in the manner of an electric resistor element in an electric heating device with heater plate.
