         2 . The boiler plant according to  claim 1 , wherein the support structure comprises attachment areas for attaching the support structure to the wall of the recovery boiler and the attachment areas allow the horizontal movement of the support structure in relation to the boiler wall. 
     
     
         3 . The boiler plant according to  claim 1 , wherein the support structure comprises attachment structures for attaching the support structure to the frame of the boiler house and the attachment structures allow the vertical movement of the wall of the boiler in relation to the frame of the boiler house. 
     
     
         4 . The boiler plant according to  claim 1 , wherein the support structure comprises attachment structures for attaching the support structure to the frame of the boiler house and the attachment structures allow the vertical turning of the support structure in relation to the frame of the boiler house. 
     
     
         5 . The boiler plant according to  claim 1 , wherein the support structure is also a bracing structure, which braces the boiler house horizontally. 
     
     
         6 . The boiler plant according to  claim 1 , wherein the boiler plant comprises a service platform and the support structure is a part of the bearing structure of the service platform. 
     
     
         7 . A support structure of a wall of a recovery boiler of a boiler plant, which structure is arranged to be attached to the wall of the boiler, wherein the support structure is also arranged to be attached to the frame of the boiler house surrounding the recovery boiler laterally. 
     
     
         8 . The support structure according to  claim 7 , wherein the support structure comprises attachment areas for attaching the support structure to the wall of the recovery boiler and the attachment areas allow the horizontal movement of the support structure in relation to the boiler wall. 
     
     
         9 . The support structure according to  claim 7 , wherein the support structure comprises attachment structures for attaching the support structure to the frame of the boiler house and the attachment structures allow the vertical movement of the wall of the boiler in relation to the frame of the boiler house. 
     
     
         10 . The support structure according to  claim 7 , wherein the support structure comprises attachment structures for attaching the support structure to the frame of the boiler house and the attachment structures allow the vertical turning of the support structure in relation to the frame of the boiler house. 
     
     
         11 . The support structure according to  claim 7 , wherein the support structure is arranged to brace the boiler house horizontally. 
     
     
         12 . The support structure according to  claim 7 , wherein the support structure is arranged to function as a support structure of a service platform. 
     
     
         13 . A method for supporting the walls of a recovery boiler of a boiler plant, which boiler plant comprises at least a frame of a boiler house and a recovery boiler, wherein the walls of the recovery boiler are supported laterally to the frame of the boiler house by a support structure. 
     
     
         14 . The method according to  claim 13 , wherein the support structure is used as a support structure of a service platform. 
     
     
         15 . The method according to  claim 13 , wherein the support structure is used to brace the boiler house horizontally.
