GAS TURBINE PLANT COMBUSTION DEVICE Russian patent published in 2021 - IPC F23R3/28 F02C7/22 

FIELD: gas turbines.

SUBSTANCE: according to the invention, adhesion of solid particles to the burner accompanying combustion in the combustion apparatus of a lean-burn gas turbine plant is eliminated and the structural reliability is improved. The combustion device of the gas turbine plant contains: a cylindrical flame tube forming a combustion chamber; and a burner including a plate with air holes, which is located at the inlet of the flame tube and includes a plurality of air holes for directing compressed air into the combustion chamber, and a plurality of fuel injectors, which are located on the side opposite the combustion chamber, with a plate with air holes located between them, with a plurality of fuel injectors each injecting fuel in the direction of a corresponding air hole, the air holes and fuel injectors forming a plurality of concentric annular lines, with a plurality of small holes having open diameters smaller than those of the open part air holes are provided through the air hole plate such that a plurality of small holes are located in the inner region of the innermost annular line of the air holes.

EFFECT: structural reliability improved, sticking of solid particles to the burner eliminated.
