Combustor support structure

Abstract

A combustor support structure of the present invention supports, at a predetermined position of a fixation member, a combustor having a combustion section which burns supplied fuel and air, and an exhaust pipe which discharges outside, combustion gas generated by burning the fuel and air. The combustor support structure includes: a first fixing section provided in the combustor; a second fixing section provided in the fixation member and fixed to the first fixing section; a first stress-absorbing section provided in the combustor; a second stress-absorbing section provided in the fixation member and connected to the first stress-absorbing section; and a stress-absorbing member interposed between the first stress-absorbing section and the second stress-absorbing section, and absorbing stress caused by thermal expansion of the combustor.

1 . A combustor support structure which supports, at a predetermined position of a fixation member, a combustor having a combustion section which burns supplied fuel and air, and an exhaust pipe which discharges outside, combustion gas generated by burning the fuel and air, the combustor support structure comprising: 
 a first fixing section provided in the combustor;    a second fixing section provided in the fixation member and fixed to the first fixing section;    a first stress-absorbing section provided in the combustor;    a second stress-absorbing section provided in the fixation member and connected to the first stress-absorbing section; and    a stress-absorbing member interposed between the first stress-absorbing section and the second stress-absorbing section, the stress-absorbing member absorbing stress caused by thermal expansion of the combustor.    
   
   
       2 . A combustor support structure according to  claim 1 , 
 wherein the first fixing section is provided in a portion of the combustor closer to an air-supply port than the combustion section, and the first stress-absorbing section is provided in a portion of the combustor closer to the exhaust pipe than the combustion section.    
   
   
       3 . A combustor support structure according to  claim 1 , 
 wherein a heat exchanger which transmits heat of the combustion gas to liquid which passes through the heat exchanger when the combustion gas passes is interposed between the combustion section and the exhaust pipe.    
   
   
       4 . A combustor support structure according to  claim 1 , 
 wherein the stress-absorbing member includes at least one of an elastomer, a rubber, and a metal thin plate corrugated to obtain resilience and elasticity.
