Title: EXHAUST DEVICE AND COMBUSTION TURBINE COMPRISING SAME
Abstract:
The present utility model provides an exhaust device and a combustion turbine comprising the exhaust device. The exhaust device comprises: a housing (100), comprising an exhaust end cavity (110) and a closed end cavity (130); an inner diffuser (300), arranged in the housing and located between the exhaust end cavity and the closed end cavity; an outer diffuser (500), configured to surround the inner diffuser and to define a gas flow passage that guides gas to flow in an axial direction of the housing into the exhaust end cavity and the closed end cavity; and a centrifugal guide member (700), arranged at a position, corresponding to the gas flow passage of the outer diffuser, on an inner wall of the closed end cavity, such that gas is guided to flow in a direction along the inner wall of the closed end cavity when the gas flowing in a direction towards the inner wall of the closed end cavity from the gas flow passage of the outer diffuser reaches the centrifugal guide member. Therefore, gas can be guided to flow in a direction along the inner wall of the closed end cavity, and a gas flow with a uniform flow velocity can be formed in the closed end cavity.
