Flame form adjusting mechanism of burner nozzle

Abstract

Abstract PURPOSE:To obtain a flame form adjusting mechanism of a burner nozzle which can retain the flame form in optimum condition by the variation of the size of an air flow out opening which is provided at the axis of a tip blow out opening of the burner nozzle by a turning operation thereof. CONSTITUTION:An air flow passage is provided at the axis of the blow out opening 11 of the tip of this burner nozzle, that is at the inside of an oil nozzle. A shaft 18 is projected to the outside of the tip opening of an air flow passage 13, and a circular collision plate 19 to which the air passed through the air flow passage 13 wound collide is provided. The clearance between the outer periphery or the circular collision plate 19 and the tip opening of the air flow passage 13 is formed as a ring shaped air blow out opening 20. An atomized fuel oil is sprayed from the blow out opening 11. In this case, the size of the clearance of the air flown out opening 20 is varied by the screwy displacement of a connection section 16 with an air supply pipe 15 being revolved, a dispersion of an air being blown out from the blow out opening 20 is changed, the flame is lengthen or shorten from its inside and an optimum flame shape is obtained according to a load.
