Diffuser structure with adjustable deflation scheme and application

The invention discloses a diffuser structure with an adjustable deflation scheme and application, and belongs to the field of combustion chambers of gas turbines. The diffuser is mainly composed of a diffuser rotatable inner plate, a diffuser outer plate, a casing, a flame tube, an inner ring cavity and an outer ring cavity. The diffuser is composed of two layers of plates, an inner plate is rotatable, an inlet section is connected with a motor through a gear, the motor drives the gear to rotate, the gear is in meshing transmission with a wheel ruler at an inlet of the inner plate, and an outlet section is connected through a bearing, so that rotation of the inner plate of the diffuser is achieved through the mode, and the inner plate and the outer plate are different in trepanning mode. Therefore, the purpose that the air inlet scheme is adjustable can be achieved by rotating the inner plate. According to the diffuser with the adjustable deflation scheme, the hole layout and the hole area can have variabilit
