SPRAY NOZZLE, AND BURNER AND COMBUSTION DEVICE EQUIPPED WITH SAME

Document Type and Number:

WIPO Patent Application WO/2014/024813

Kind Code:

A1

Abstract:

The present invention provides a spray nozzle with which atomization of a spray fluid can be promoted and the amount of a spray medium used, as well as the pressurization of the spray medium, can be reduced. This spray nozzle is characterized by being equipped with: at least two spray fluid flow paths in which a spray fluid flows; at least two spray medium flow paths that converge with a respective spray fluid flow path at a first convergence part; at least two mixed fluid flow paths in which the fluid mixture of the spray fluid and the spray medium that have converged at the respective first convergence parts flows, and which are formed opposing one another and have a second convergence part in which the fluid mixture becomes opposing flows that collide and converge; and an outlet hole from which the fluid mixtures that have converged at the second convergence part is sprayed. In addition, bend parts that change the direction of flow of the mixed fluid are formed in the mixed fluid flow paths, in the interval between the first convergence parts and the second convergence part.
