Abstract
This invention provides a liquid atomizing nozzle which utilizes a swirling flow of gas to form a liquid film in as uniform thickness as possible in a circumferential direction, and in which blockages are difficult to develop, and which can facilitate atomization by further reducing the size of the droplets which disperse from the front end. A liquid injected into an annular space 7 through liquid passages 14 formed in an outer cylinder 2 in an incline to the radial direction, flows within the annular space 7 having a component swirling in the circumferential direction. Air which flows into the annular space 7 through air passages 10 formed inclined in the same direction as the liquid passages in the outer cylinder 2, develops a swirling flow Ac within the annular space 7, acts upon the injected liquid to spread it onto an inner wall 5 of the outer cylinder 2, and further improving the uniformity of the thickness of the liquid film in a circumferential direction. When the liquid film disperses from the front end edge 16 of the outer cylinder 2, atomization is facilitated and the size of the droplets may be reduced further.
