FIELD: power engineering; gas turbines. ^ SUBSTANCE: proposed gas-turbine device contains heat accumulating segments arranged opposite to working blades on support over perimeter on casing of gas turbine. Working blades are arranged over perimeter on rotor of gas turbine, guide vanes are arranged near heat accumulating segments over perimeter between casing of gas turbine and rotor, working blades and guide vanes being arranged in hot has channel of gas turbine. Placed between guide vanes and heat accumulating segments is at least one sealing member installed over perimeter and separated by protective screen in direction of hot gas channel. ^ EFFECT: protection of turbine casing from penetration of hot gases. ^ 9 cl, 3 dwg |
