Abstract: A gas burner is provided that simulates wood burning fire and the glowing amber effect of real wood or coal burning. The burner comprises a burner pan which is covered by a refractory material. Burner ports are formed through the refractory material.

Abstract: A simulated-flame fireplace having a housing with a firebox which can be viewed through a transparent front door panel. A translucent simulated ember bed rests on the floor of the firebox, and a log-supporting andiron rests on the ember bed. A video-image projector is mounted on the housing to project an image of an actual wood fire into the firebox. A beam-splitting transparent and partial reflecting panel is supported within the firebox to reflect the flame image toward a viewer, and to enable direct viewing of the firebox interior. The projection and beam splitter are oriented to create a viewer-perceived illusion of the flame image as superimposed on the logs as in an actual log-burning fireplace. The illusion may be enhanced by the addition of audio reproduction of fire sounds, and variable-intensity lighting of the firebox walls and ember bed.

Abstract: A gas log set for a fireplace has sets of gas jets arrayed to provide a pleasing distribution of flames around and between several cast-concrete simulated logs. A glowing-ember effect is created beneath a front log and between the logs by strips of rock wool which radiate when heated. Both the simulated logs and the rock wool are doped with metallic salts which convert the complete-combustion blue coloration of a gas flame to a yellow-orange color which closely simulates the appearance of a natural wood fire.
