Abstract:
A gas-fired cooking device, comprising:a braising cavity having a generally vertical peripheral wall disposed thereabout and a generally planar heated surface generally defining a lower boundary thereof; said peripheral wall and said heated surface cooperating to allow fluid to be contained in said braising cavity; a plurality of generally front-to-back heating chambers disposed below said heated surface, each having a lower zone and an upper zone, said upper zone disposed below said heated surface and above said lower zone; each of said heating chambers heated by at least one respective gas burner, fed by natural draft, generating hot combustion gases in said lower zone, at least a portion of said hot combustion gases flowing from said lower zone to said upper zone; each of said heating chambers having sidewalls and downwardly extending flow-restricting walls that cooperate with said sidewalls to create said upper zone for transiently retaining therein hot combustion gases from said lower zone; and said upper zone having relatively slow average front-to-back flow rate therein and said lower zone having relatively faster average front-to-back flow rate therein.
