GAS LINE OF GAS-TURBINE POWER PLANT EXHAUST DUCT Russian patent published in 2007 - IPC F01D25/28 

FIELD: mechanical engineering: gas-turbine power plants.

SUBSTANCE: invention relates to thermal protection of objects and it can be used in manufacture of gas lines of exhaust ducts of gas-turbine power plant. Proposed gas line of exhaust duct contains inner load-bearing shell with supports on foundation BASE, outer protective shell and heat insulating material in between. Outer shell is rigidly attached to at least one of supports of load-bearing shell and is connected with others by means of horizontal round rod. Said rod passes square to axis of gas line through hole in support and through slots in outer shell. Slots are made with length not less than value of expansion of load-bearing shell.

EFFECT: improved reliability and manufacturability of gas line of exhaust duct owing to reduced number of components and dispensing with heat transfer and deformable couple elements between outer and inner shells.
