A gas fired infrared burner includes a burner body with a primary inlet for gaseous fuel and air, the burner body defining a primary premixing chamber for receiving gaseous fuel and air from the primary inlet. An emitter arrangement is configured and positioned such that gaseous fuel and air flows through the emitter arrangement to be combusted at an external surface of the emitter arrangement. The burner body includes an auxiliary inlet for gaseous fuel and air, and the burner body defines an auxiliary premixing chamber for receiving gaseous fuel and air from the auxiliary inlet. The emitter arrangement includes an auxiliary emitter segment that receives gaseous fuel and air from the auxiliary premixing chamber such that combustible gases emitted from the auxiliary emitter segment can be ignited even when no combustible gases are being emitted from portions of the emitter arrangement that are fed from the primary premixing chamber.

A fireplace and method of manufacturing a fireplace. Embodiments of the fireplace comprise a combustion chamber, a front opening allowing viewing within the combustion chamber, and a back wall opposite the front opening. The back wall can be controllably switched between an opaque state and a transparent state. A combustion region between the front opening and the back wall is adapted to provide a flame. A controller coupled to the back wall enables a user to switch the back wall between the opaque and transparent states. In embodiments the back wall comprises a glass panel and switchable film on the glass panel. The controller is coupled to the switchable film.

A burner system for a cooking device has at least one burner surface wherein the at least one burner surface is designed in such a way that the burner system has a low minimum power density with homogeneous temperature distribution at the same time. In a first aspect, the burner system includes a fuel supply and a first burner surface for burning the fuel that is provided downstream of the fuel supply. The burner system includes a second burner surface for afterburning that is separate from the first burner surface and is provided downstream from the first burner surface. Moreover, a method for operating the burner system is shown.

A cooking and cooling apparatus, including a main body to receive at least one item thereupon, a cooking unit disposed on at least a portion of a top surface of the main body to cook at least one food item thereon, and a cooling unit disposed within at least a portion of the main body to keep contents stored within at a cool temperature.

A gas-fired, powered infrared burner unit comprising a perforate distribution plate configured as a tray and a porous foam metal burner element carried in the tray, the combination overlying the open top of a plenum box and sealingly fastened to an edge flange of said box by a retainer having a surrounding flange fastened to the plenum box flange by welding, staking or other means so as to eliminate the need for a gasket. The foam metal medium is constructed of a foam metal alloy to have a pore size of 1000 micros±5%, and produce, along with the perforations in the distribution tray, a port loading of between about 850 and 1,000 BTU/in.sup.2.
