Abstract
A coolable casing of a gas turbine or the like, with a plurality of arcuate casing segments (,) which are arranged so as to be contiguous with one another in a circumferential direction, to form an essentially closed casing ring surrounding a rotor (,), in particular of a high-pressure turbine, at least one annular casing cooling chamber (,) which is formed in the radial direction between the casing segments (,) and arcuate guide segments (,) provided with a multiplicity of passage orifices (,), at least one air guide chamber (,) which is formed in the radial direction between the guide segments (,) and at least one carrier segment (,), and at least one air supply duct (,) which is made on the carrier segment (,) and opens into the air guide chamber (,), the guide segments (,) being mounted loosely with radial play. This ensures stress-free reception, even in the case of intensive operations having high temperature gradients.
