Abstract
In this method of preventing deformation in a turbine casing of a gas turbine, in a turbine casingthere is arranged a buffer tank. In this buffer tankthere are formed a stagnation part agitation air openingwhich ejects part of the air from an air compressoras stagnation part agitation air Gatoward a stagnation partwithin the turbine casing, and an overall agitation air openingwhich ejects overall agitation air Gafor agitating gas held in an upper space within the turbine casing. In the buffer tankthere is provided a partition wallwith through holesformed therein serving to resist air from the air compressor, in order to make the ejection speed of the overall agitation air lower than the ejection speed of the stagnation part agitation air.
