Gas turbine annular combustor arrangement

A combustor arrangement, the combustor arrangement being annular and being arranged about an axis, the axis defining an axial direction, comprising:

• an annular combustion chamber;
• an annular housing that houses a plurality of burners and the annular combustion chamber;
• the plurality of burners arranged circumferentially about the axis inside the annular housing;
• an annular space being defined between the housing, the plurality of burners and the annular combustion chamber, the annular space arranged to guide a compressed fluid;
• a plurality of stiffening plates, each arranged within the annular housing, wherein two adjacent ones of the plurality of burners are separated by one of the stiffening plates;
• a combustor separating wall arrangement separating the annular space from the annular combustion chamber and providing openings for the plurality of burners;
• further plates extending into the annular space;
• wherein the stiffening plates are arranged angled to, and connected to
• the combustor separating wall arrangement and
• two boundary walls of the housing, and
• the further plates.
