FIELD: turbine.
SUBSTANCE: invention relates to steam and gas turbines. Turbine with heating of flow part at least includes a housing with a channel for gas or liquid heating flow part, rotor, vanes; inlet branch pipe for gas or liquid heating flow section, outlet branch pipe for gas or liquid heating flow section; working medium inlet branch pipe, outlet branch pipe of working medium, bearing assembly, end seal. All parts of flow section, including turbine housing with channel for gas or liquid flow section heating is carried out to increase heat exchange surface with tubes, ribs, for heating working medium during its expansion in turbine, thus producing isothermal expansion process in turbine.
EFFECT: invention is aimed at increasing efficiency of steam and gas turbines, as a result, higher efficiency.
