Abstract (en)

[origin: WO8403752A1] With this small oil burner for an hourly oil throughput in a range not exceeding 5 kg, with a nozzle head (3) to which is added a heat exchanger (1), having at least one injection nozzle (7) connected to an oil supply and secured by a central attachment, as well as an outer burner pipe (4) surrounding the attachment of the injection nozzle (7) while forming a combustion air channel (5) connected to an air supply, it is possible to obtain, while keeping the basic design of small oil burners known heretofore, a high efficiency and a low pollution level since the oil flow rate may be controlled as a function of the load by the injection nozzle (7) designed as a non-return vortex injection nozzle, respectively a simplex injection nozzle with constant cross-section area, and since the air supply corresponding to the instantaneous oil flow rate may be controlled by the burner pipe (4); this air supply may be regulated by the burner pipe (4) by means of the axial displacement of a regulation element (ring 30) displaceable to oppose a return force and axially and movably arranged in the nozzle head (3), according to a function depending on the load and containing at least the variable pressure of the oil remaining at the injection nozzle (7), respectively to a function acting on said oil pressure.
