Abstract
A diffuser assembly is provided herein. In certain embodiments, the diffuser assembly may include an outer boundary member and an inner boundary member, with the inner boundary member being positioned radially inward of the outer boundary member. The diffuser assembly also may include an exhaust flow path defined between the outer boundary member and the inner boundary member. Further, the diffuser assembly may include at least one flow deflecting member operatively attached to the outer boundary member. The flow deflecting member may be adjustable about the outer boundary member to produce a substantially uniform velocity distribution within the exhaust flow path.
Claims20
A diffuser assembly, comprising:
- an outer boundary member;
- an inner boundary member positioned radially inward of the outer boundary member and defining an exhaust flow path therebetween;
- and
- at least one flow deflecting member operatively attached to the outer boundary member, wherein the flow deflecting member is adjustable about the outer boundary member to produce a substantially uniform velocity distribution within the exhaust flow path.
A method for use with a gas turbine engine, comprising:
- flowing a fluid in an exhaust flow pathway defined between an outer boundary member and an inner boundary member;
- adjusting a position of at least one flow deflecting member operatively attached to the outer boundary member;
- and
- producing a substantially uniform velocity distribution within the exhaust flow path.
A gas turbine system, comprising:
- an HRSG assembly;
- a turbine assembly;
- and
- an exhaust diffuser assembly in communication with the turbine assembly and the HRSG assembly, the exhaust diffuser assembly comprising:
- an outer boundary member;
- an inner boundary member positioned radially inward of the outer boundary member defining an exhaust flow path therebetween;
- and
- at least one flow deflecting member operatively attached to the outer boundary member, wherein the flow deflecting member is adjustable about the outer boundary member to produce a substantially uniform velocity distribution within the exhaust flow path, which is supplied to the HRSG assembly.
