MULTI-NOZZLE BURNER MODULE OF GAS TURBINE PLANT COMBUSTION CHAMBER Russian patent published in 2024 - IPC F23R3/00 

FIELD: machine building.

SUBSTANCE: invention relates to devices for preparation and combustion of single- and multicomponent fuels in combustion chambers of gas turbine power plants. Multi-nozzle burner module of a combustion chamber of a gas turbine plant contains burners, each of which is equipped with a fuel nozzle, an insert, a perforated plate, in which burners are integrated. To supply air to the area of fuel-air mixture formation in the burners there is an air supply channel, at the end of which there is a tangential nozzle inlet, at the outlet of which compressed air, interacting with fuel, forms a fuel-air mixture. Nozzle inlet is a system of four air supply channels distributed along the circumference with pitch of 90 degrees. In burners there is a diffuser nozzle, through which the fuel-air mixture enters the inner space of the insert, forming a flame front.

EFFECT: using invention provides increased intensity of mixing of fuel and compressed air, increasing completeness of additional oxidation of intermediate reaction products to carbon dioxide and water vapors, increasing cooling efficiency of insert walls, reducing flame length in axial direction.
