FIELD: gas-turbine plants. SUBSTANCE: gas-turbine plant has combustion chamber housing lined from inside with solid ceramic stones provided with coating, rotor furnished with blades and casing with guide vanes. Coating applied directly to ceramic stones consists of upper heat-and-corrosion resistant layer and lower layer which increases adhesion. At least first blades at turbine side are provided with ceramic heat insulating layer. Coating can consist of metallic material, can be made multiple-layer or in form of ceramic layer. EFFECT: improved protection of combustion chamber and blades from thermal load, increased service life of turbine blades. 4 cl, 2 dwg
