GAS CHANNEL FOR GAS TURBINE AND GAS TURBINE COMPRISING SUCH GAS CHANNEL Russian patent published in 2015 - IPC F01D9/06 F01D25/26 

FIELD: machine building.

SUBSTANCE: gas channel for a gas turbine is formed by concentrical inner and outer casings, the latter encloses the former at a distance. The inner casing and the outer casing are interconnected by a variety of radial supporting poles. The inner casing, the outer casing and the radial supporting poles are fitted by heat resistant lining to be protected against waste gases. The linings of the supporting poles, outer casing and inner casing are divided into a variety of separate segments fixed on a supporting structure providing for free individual thermal expansion of separate segments. The supporting structure comprises a variety of mounting units at the outer and inner casings. The mounting units are fixed on the concentrical shell by the radial poles, and the mounting units of the respective segments are fixed by screws. Another invention of the group relates to a gas turbine comprising the said gas channel through which waste gases are removed.

EFFECT: group of inventions allows for simplified maintenance of the turbine gas channel and for reduced thermal stresses in it.
