GAS TURBINE PLANT Russian patent published in 2012 - IPC F02C7/22 

FIELD: machine building.

SUBSTANCE: gas turbine plant comprises a turbine and a compressor installed on a single shaft, a combustion chamber communicated with its outlet to the turbine inlet and with its inlet to the compressor's outlet, a manifold of fuel supply and a control system. The combustion chamber is equipped with mixing elements arranged with a channel of air flow in the form of a diffuser with a cone angle of 6-12° and a channel of fuel flow in the form of a cylindrical attachment, coaxially arranged in the inlet part of the diffuser. The fuel supply manifold is connected with cylindrical attachments. The control system is equipped with stop valves and an ignition device. Mixing elements are installed at least in two rows along the circle on the circular combustion chamber or along concentric circumferences at the combustion chamber of tubular and circular shape. At the same time the mixing elements are arranged at the distance of not more than three diameters of the diffuser's outlet part, and between them and around them there are holes for air passage. Some cylindrical attachments of mixing elements are combined into separate units with the fuel supply manifold in the form of a header, at the inlet of which there are throttling elements installed.

EFFECT: increased efficiency and resource of gas turbine plant operation and reduction of hazardous emissions.
