Abstract
A modified version of an induction nozzle having a central “see-through” passive zone protects the induction ports from crosswind disruption. Modified features include: (i) a full-length wind band extending below the induction port inlets; (ii) multiple full-length mounting brackets, which impede circumferential crosswind flow around the nozzle; (iii) a transverse induction port separation plate, orthogonal to the centerlines of the induction ports; and (iv) elimination of one induction port opening.
Claims5
An induction nozzle assembly for vertical connection to a pressurized exhaust gas outlet, comprising:
- a tubular or frusto-conical nozzle and a frusto-conical wind band, which is attached in converging annular spaced relation to the exterior of the nozzle by multiple mounting brackets;
- wherein the nozzle comprises a nozzle inlet, which transitions into one or two arcuate nozzle branches, and wherein each of the nozzle branches terminates in an arcuate discharge outlet;
- wherein the arcuate nozzle braches and the arcuate discharge outlets are circumferentially disposed around a central passive zone within the interior of the nozzle;
- wherein the central passive zone pneumatically communicates with an ambient atmosphere outside the nozzle through one or two induction port inlets into the nozzle;
- and
- wherein the wind band extends from at or below the induction port inlets to above the discharge outlets of the nozzle, thereby shielding the induction port inlets and the central passive zone from crosswinds.
