Abstract
Abstract The invention concerns a space-heating burner particularly for furnaces, which produces optimum mixing of the two combustion components, characterized by the fact that the oxidant is stored under pressure in an enclosed space comprising a delivery tube lengthened on the outside by a drip-flap or lip set at a tangent to the outlet, then progressively turned back so that the jet is directed perpendicular to the outlet direction of the delivery tube, a standard type of fuel outlet nozzle being positioned close to this drip-flap in such a way that the oxidant thus injected draws up by suction the carburant forced out of the nozzle, to form a homogenous combustion mixture.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
148 words
A burner especially for a furnace for heating products such as ceramics, terra-cotta or the like, the burner comprising an oxidant delivery tube having an outlet with a deflecting convex lip for directing oxidant tangentially to the outlet, the burner being characterized in that it comprises two chambers and a nozzle, one of said chambers being an oxidant chamber communicating with the inlet of said delivery tube, and the other of said chambers being a fuel chamber communicating with the inlet of said nozzle, said delivery tube outlet being a rectilinear slit and the nozzle outlet being located near said deflecting lip of the delivery tube so that oxidant issuing from said slit will draw in surrounding atmosphere of the furnace and mix with fuel issuing from the nozzle in order to produce a jet directed in a path substantially parallel to the direction of the deflecting lip.
Claim 2
Dependent Claim
148 words
A burner especially for a furnace for heating products such as ceramics, terra-cotta or the like, the burner comprising an oxidant delivery tube having an outlet with a deflecting convex lip for directing oxidant tangentially to the outlet, the burner being characterized in that it comprises two chambers and a nozzle, one of said chambers being an oxidant chamber communicating with the inlet of said delivery tube, and the other of said chambers being a fuel chamber communicating with the inlet of said nozzle, said delivery tube outlet being a rectilinear slit and the nozzle outlet being located near said deflecting lip of the delivery tube so that oxidant issuing from said slit will draw in surrounding atmosphere of the furnace and mix with fuel issuing from the nozzle in order to produce a jet directed in a path substantially parallel to the direction of the deflecting lip.
Claim 3
Dependent Claim
37 words
A burner as defined in claim 1, characterized by the fact that a second oxidant delivery tube having an outlet with a deflecting convex lip is located beside said jet path for adding oxidant to said jet.
