System for conditioning flow through a nozzle

Abstract

A system for conditioning flow through a plurality of nozzles arranged in a combustor includes a shield circumferentially surrounding at least a portion of the plurality of nozzles and a plurality of baffles disposed circumferentially around the shield. Each baffle is circumferentially disposed between adjacent nozzles.

1 . A system for conditioning flow through a plurality of nozzles arranged in a combustor, comprising:
 a. a shield circumferentially surrounding at least a portion of the plurality of nozzles; and   b. a plurality of baffles disposed circumferentially around said shield, wherein each baffle is circumferentially disposed between adjacent nozzles.   
     
     
         2 . The system as in  claim 1 , wherein each baffle comprises a substantially triangular surface. 
     
     
         3 . The system as in  claim 1 , wherein each baffle comprises at least one concave surface. 
     
     
         4 . The system as in  claim 1 , wherein at least a portion of each baffle extends radially inward from said shield. 
     
     
         5 . The system as in  claim 1 , wherein each baffle is radially disposed completely inward of said shield. 
     
     
         6 . The system as in  claim 1 , further comprising a casing circumferentially surrounding at least a portion of said shield. 
     
     
         7 . The system as in  claim 6 , wherein each baffle is fixedly connected to at least one of said shield or said casing. 
     
     
         8 . The system as in  claim 6 , wherein each baffle extends radially between said shield and said casing. 
     
     
         9 . A system for conditioning flow through a plurality of nozzles arranged in a combustor, comprising:
 a. a shield circumferentially surrounding at least a portion of the plurality of nozzles;   b. a casing circumferentially surrounding at least a portion of said shield; and   c. a plurality of baffles disposed circumferentially around said shield.   
     
     
         10 . The system as in  claim 9 , wherein each baffle comprises a substantially triangular surface. 
     
     
         11 . The system as in  claim 9 , wherein each baffle comprises at least one concave surface. 
     
     
         12 . The system as in  claim 9 , wherein at least a portion of each baffle extends radially inward from said shield. 
     
     
         13 . The system as in  claim 9 , wherein each baffle is radially disposed completely inward of said shield. 
     
     
         14 . The system as in  claim 9 , wherein each baffle is fixedly connected to at least one of said shield or said casing. 
     
     
         15 . The system as in  claim 9 , wherein each baffle extends radially between said shield and said casing. 
     
     
         16 . The system as in  claim 9 , wherein each baffle is circumferentially disposed between adjacent nozzles. 
     
     
         17 . A system for conditioning flow through a plurality of nozzles arranged in a combustor, comprising:
 a. an annular passage circumferentially surrounding the plurality of nozzles; and   b. a plurality of baffles disposed circumferentially around the plurality of nozzles, wherein each baffle is circumferentially disposed between adjacent nozzles.   
     
     
         18 . The system as in  claim 17 , wherein each baffle comprises at least one of a substantially triangular surface or a concave surface. 
     
     
         19 . The system as in  claim 17 , wherein each baffle is radially disposed completely inside said annular passage. 
     
     
         20 . The system as in  claim 17 , wherein at least a portion of each baffle extends radially inward from said annular passage.
