Title:
SPRAY NOZZLE, BURNER WITH SPRAY NOZZLE, AND COMBUSTION DEVICE WITH BURNER
Document Type and Number:
WIPO Patent Application WO/2014/097812
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a spray nozzle which both promotes atomization of the whole spray fluid by promoting atomization of the central portion of the spray in which the particle diameters in the spray fluid are relatively large, and reduces the pressurizing force or the use amount of the spray medium used in atomizing the spray particles. The spray nozzle (1) is configured from an outer surface partition wall (15) and an internally housed structure (16). The spray nozzle is provided with a spray fluid flow path (4) circulating the spray fluid (2), a spray medium flow path (6) circulating the spray medium (3), and a first mixing area (91) which communicates with both flow paths and in which a mixed fluid (8) is formed. Mixed fluid flow paths (9, 10) down which the mixed fluid (8) flows are arranged oppositely, and the currents of the mixed fluid (8), which are opposite in a second mixing area near an outlet (11), collide, and the mixed fluid (8) is sprayed out externally from the outlet (11). Also, the spray nozzle (1) is provided with a second spray medium flow path (17) circulating a different spray medium (18) and arranged so as to communicate with the mixed fluid flow paths (9, 10).
