Abstract
A fireplace accessory serves as a combustion efficiency improvement device. The structure is a tubular element open along a front side and in the form of an arch lying upon its side for partially enveloping logs or other fuel. A horizontal combustion region is provided within the structure for at least partial exposure of the fuel through the frontal opening by the structure, the frontal opening facing toward a room area to be heated by the burning fuel. The arch configuration both cradles the fuel and insulatively and radiantly encloses it. A double-walled configuration, preferably curved stainless steel sheets with thermally insulating, refractory material between them, defines an interior surface which becomes heated to and is maintained by the combustion at extraordinarily high temperatures. This causes radiation of thermal energy forwardly from the interior surface for intensifying combustion of the fuel, for causing substantially complete burning of volatiles released by the fuel during combustion, and for redirecting thermal energy generated by the combustion through the opening into the room area to be heated. End plates support the tubular element in horizontal orientation.
