Abstract (en)

[origin: EP1505261A1] The device has a circular control box (22) surrounding a fixed ring set of a gas turbine. The box has two annular air circulation rails that are spaced from each other. The rails have perforations that modify temperature of the ring set. Hollow spacers (32) connect an air supply channel (28) to the rails in order to supply air in the rails and permit the air to be discharged in the ring set.
