Abstract
A discharge apparatus for dispersing exhaust gases discharged into the atmosphere and eliminating the steam plume, is disclosed. A plurality of conical diffusing elements are supported in spaced nested relationship along the discharge axis of the exhaust duct. Continuous compressed air is ejected into the central portion of each conical diffusing element.
Claims6
A discharge apparatus for hot exhaust gases, comprising:
- (a) a discharge stack with a vertically oriented duct having an open end at the top thereof,
- (b) a plurality of conical diffusing members supported adjacent the open end and concentric about the axis of said duct, said diffusing members being spaced longitudinally apart a distance along said axis, each of said diffusing members beong open at opposite ends thereof with the upper end of each member being nested within but spaced from the lower end of the most adjacent conical member, and
- (c) means providing for injection of a continuous jet of compressed air into each of said diffusing members, said jets being aligned with the axis of the associated diffusing member whereby the flow of exhaust gases exiting from said open stack top is cooled by said jets, diluted by the ambient air aspirated into and between said conical members and dispersed homogenously into the general mass of the atmosphere without the formation of a visible plume.
