Abstract
A solid-fuel effect gas fire comprises an open-topped tray containing a mass of particulate refractory material, means for introducing gas into the tray to percolate upwards to the surface of the refractory material, an apertured or porous plate overlying, but spaced from, part of the surface of the particulate material, and a plurality of refractory bodies, shaped and colored to simulate solid fuel, heaped on the plate and the part of the tray which is not covered by the plate. In use, the fire operates with a mixture of luminous and non-luminous flames and closely resembles a conventional solid-fuel fire. The ratio of carbon dioxide to carbon monoxide in the gases of combustion is from 1:0.01 to 1:0.005.
