Abstract: The present invention is related to a gas burner capable of bringing artificial “fuel” disposed thereon to incandescence, known as a “living-flames” gas burner, for use in a single-heating appliance, comprising a multi-panel element made of rigid gel-cast molded ceramic fibers or of bio-soluble ceramic fibers.

Abstract: The invention concerns a multiple-fuel heating apparatus wherein: the combustion chamber (1) forms the main support structure of the heating apparatus and is made of sheet metal bent and welded (2) so as to be completely sealed, optionally except at the joint with said door; the elements (20) forming the outer cover are fixed to the combustion chamber, the fixing elements not passing through the chamber and said elements not being necessarily fixed together.

Abstract: A heating apparatus comprises a combustion chamber, formed of an assembly having a rear wall, two lateral walls, an upper wall and a lower wall. The combustion chamber has at least one outlet for flue gases. The walls forming said combustion chamber are configured to have standard dimensions so that the heating apparatus is configurable to operate with a variety of fuels including solid fuels, liquid fuels and gas fuels.

Abstract: Disclosed is a window construction for a heater, which generally has a frame and at least one panel fitted on the frame. The frame and the at least one panel are usually made of different materials having different expansion coefficients. An expansion compensator made of bimetallic material is provided to the window located between the frame and a distal portion of the at least one panel to otherwise contact the frame. The expansion compensator compensates the differential expansions occurring between the frame and the at least one panel as the heater temperature changes.

Abstract: A liquid hydrocarbon burner includes a single-walled pot; and a catalytic element placed centrally in the single-walled pot and comprised of an assembly of blades which are arranged concentrically around a vertical axis, which have in axial cross-section a mushroom shape, and which blades have respective upper parts and lower parts with respective weights such that the weight of the lower parts is greater than that of the upper parts. A process for preparing a sheet of chromium inox steel which is catalytically active for hydrocarbon combustion so that it is suitable for making blades for a catalytic element of a liquid hydrocarbon burner includes providing a sheet of chromium inox steel having a silicon content which exceeds 0.40%.+-.0.05 so that the chromium inox steel is refractory to the core; and pickling the sheet of chromium inox steel by treatment thereof with an acid effective to pickle chromium inox steel and render at least the surface thereof catalytically active for hydrocarbon combustion.
