ATOMIZATION TYPE PETROLEUM BURNER

摘要

PURPOSE:To enable a complete combustion to be carried out by a method wherein waste oil or other heavy oil is atomized under utilization of a principle of atomization blowing except a forced injection under pressure when the waste oil or other heavy oil is completely ignited. CONSTITUTION:A combustion inner cylinder 14 is arranged to enclose a funnel- like fuel injection nozzle 1 located at a central part of an inner pipe opening 3a of a combustion air supplying pipe 3 having its extremity end of double structure. A neck part 5 is formed at a combustion air passage by the inner cylinder 14 and a nozzle edge 1a. An air passage 17 is formed outside the inner cylinder, a combustion outer cylinder 15 is arranged at an opening of the outer cylinder of the air supplying pipe 3 and then the combustion cylinder is of a double structure. In addition, a static mixer 16 is arranged within the inner cylinder to construct an atomization burner. The combustion cylinder of double structure is constructed such that an inner surface of the inner cylinder at its extremity end 14a is tapered outwardly to form an opening and an extremity end 15a of the outer cylinder is coincided with an extention line of the tapered state and at the same time the outer surface of the outer cylinder at its extremity end 15a is tapered inwardly.
