EXHAUST GAS MANIFOLD AND THE GAS TURBINE Russian patent published in 2018 - IPC F01D25/30 

FIELD: engines and pumps.

SUBSTANCE: exhaust gas manifold for the gas turbine comprises the chamber having a wall on the gas inlet side, the gas inlet opening, which is located in the mentioned wall and the gas outlet opening. First connectors are disposed around the mentioned gas inlet opening and are intended to connect the mentioned manifold to the diffuser of the exhaust gases of the gas turbine. Second connectors are disposed around the mentioned gas inlet opening and are adapted to connect the mentioned manifold to the gas turbine support plate. Each second connector is disposed substantially diametrically opposite to the respective first connector relative to the center of the gas inlet opening while forming the pairs of the first connector and of the second connector. Installation of the mentioned manifold on the exhaust gas diffuser of the gas turbine in the selected one out of several different angular positions is provided by using an appropriate pair of one first connector and one second connector. In this case, the first connectors are designed and arranged in order to provide for reception of horizontal, not vertical loads.

EFFECT: such an arrangement provides for the possibility of selective use of pairs from one first connector and one second connector for connecting the manifold to the exhaust diffuser of the gas turbine at the selected one out of several different angular positions depending on the requirements for the deployment plan or it may be changed during transportation of the gas turbine module in order to reduce its dimensions and the occupied supporting surface, also the limitations of mechanical stresses created by the exhaust gas manifold in the turbine exhaust manifold are ensured.
