Appl. No.:

12/986657

Inventors:

AARON ALEXANDER - Oologah OK, US
LAQUINNIA LAWSON, JR. - Tulsa OK, US
RICHARD KING - Mobile AL, US

Assignee:

BRADEN MANUFACTURING, LLC - Tulsa OK

International Classification:

F02C 7/00
F15D 1/02

US Classification:

60 395, 137833

Abstract:

A gas turbine transition into an emission reduction catalyst is improved by adding properly curved surfaces so as to induce the Coanda effect. Such a surface allows for a reduction in pressure drop, shorter duct lengths, and elimination of some or all of traditionally used flow re-distribution devices.

International Classification:

F01N 13/08

US Classification:

60694

Abstract:

An exhaust duct for a gas turbine includes a transition section having an inlet for receiving turbine exhaust gas and a relatively larger outlet for interfacing with an auxiliary section housing an auxiliary device. The transition section has an interior surface extending from the inlet to the outlet. The interior surface has a segment generally adjacent to the inlet that is curved to induce a Coanda effect in which the turbine exhaust gas is caused to flow along said curved surface and to expand for distribution of the turbine exhaust gas over the auxiliary device in the auxiliary section.
