Abstract (en)

The present invention relates to an exhaust diffuser assembly (1), particularly for a stationary gas turbine, and a method incorporating the same. The proposed exhaust diffuser assembly (1) comprises a longitudinal axis (2), a diffuser inlet (3) for receiving a turbine mainflow gas (5), a diffuser outlet (4), and a diverging diffuser wall (7) having an adjustable geometry and forming a conduit for flow of said gas (5) therethrough from said diffuser inlet (3) to said diffuser outlet (4). The diffuser wall (7) has a divergence angle '±' with respect to said longitudinal axis (2). The proposed diffuser assembly (1) further comprises diffuser geometry control means (9,10) for controlling a recovery of pressure from said gas (5) between said diffuser inlet (3) and said diffuser outlet (4) by adjusting said divergence angle '±' of said diffuser wall (7) to cause a resultant flow field of said gas (5) that is attached to said diffuser wall (7).
