Abstract (en)
[origin: EP2107304A1] Swirl spraying nozzle comprises a nozzle body (2) having a hollow cylinder (5) with a base (4) closing the cylinder on one side and a head (6) closing the cylinder on the other side so that a swirl chamber (3) is formed in the nozzle body. Inlet holes (7, 8) are formed in the cylinder close to the base and are arranged perpendicular to the longitudinal axis of the cylinder and positioned at an angle in the peripheral direction of the cylinder. A further outlet hole (9) is arranged in the head. Independent claims are also included for the following: (1) Tuyere connection with the swirl spraying nozzle; and (2) Method for producing a swirl spraying nozzle. Preferred Features: The diameter-height ratio of the nozzle body is less than one.
