A radiant fuel support for an artificial fuel-effect gas fire in the form of a plaque of refractory material having an upper surface formed with a series of ridges with channels therebetween, the ridges being designed to support artificial fuel elements placed thereon and the channels being designed to receive gas flames impinging on the surface thereof; the support being mounted in an artificial fuel-effect gas fire having a series of flame producing means, with each such means being arranged so that a flame therefrom would impinge on the surface of one of the channels at a shallow, glancing angle thereto, the artifical fuel elements being arranged on the ridges to bridge the channels; by this means the channels and the undersurfaces of the fuel elements can be heated by the flames which would also appear as naked flames above the support and between the fuel elements.
A radiant fuel support for an artificial fuel-effect gas fire and in the form of a plaque of refractory material having an upper surface and a lower surface, the upper surface being formed with a series of ridges with closed-bottom channels therebetween, the ridges being designed to support artificial fuel elements placed thereon so as to bridge the channels and the channels being open-ended at least at one end and designed to receive gas flames playing directly onto the upper surface thereof at a shallow glancing angle thereto, said plaque being devoid of flame or fuel passages extending therethrough between its upper and lower surfaces.
In combination for forming an artificial fuel-effect gas fire, a radiant fuel support in the form of a plaque of refractory material having an upper surface and a lower surface, the upper surface being formed with a series of ridges with channels therebetween, the ridges being designed to support artificial fuel elements placed thereon so as to bridge the channels and the channels being designed to receive gas flames impinging on the surface thereof, and flame producing means for producing a series of flames arranged so that each flame therefrom would play directly onto the upper surface of a respective one of the channels at a shallow glancing angle thereto.
