Abstract
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/in2.
Claims10
A powered, gas-fired infrared burner unit comprising:
- a plenum box for receiving a fuel/air mixture under pressure and having a top opening surrounded by an integral edge flange, said box having an inlet for said fuel/air mixture;
- a perforated distribution tray having a face and a surrounding lip and dimensioned to fit over the plenum box opening and onto the edge flange;
- a foam metal combustion medium in plate form fitted directly over and contactingly against the face of the distribution tray such that combustion of the fuel/air mixture takes place in said foam metal medium;
- and
- a retainer member having a bezel contactingly overlying the surface, the retainer member having a surrounding flange overlying and fastened to the plenum box flange to capture the distribution tray and medium, sealingly secure the plate and panel to the plenum box edge flange with the perforated distribution tray underlying the medium and a majority of the top surface of the medium exposed for radiation.
