COMBUSTION CHAMBER WITH A LOW CONTAMINATION LEVEL AND METHOD FOR COMBUSTION CONTROL THEREFOR Russian patent published in 2022 - IPC F23R3/28 

FIELD: combustion chambers.

SUBSTANCE: invention relates to a combustion chamber with a low contamination level and to a method for combustion control therefor. The combustion chamber with a low contamination level comprises the head part of the combustion chamber, containing a main mixture combustion stage and a preliminary combustion stage, the main mixture combustion stage comprises a channel of the main mixture combustion stage and a swirler of the main mixture combustion stage, located in the channel of the main mixture combustion stage, wherein the main mixture combustion stage additionally comprises a preliminary film plate located in the channel of the main mixture combustion stage, and the preliminary film plate is radially divided into a preliminary film plate of the external layer and a preliminary film plate of the internal layer, wherein the positions and directions of injection of the fuel injection points of the main mixture combustion stage are configured to control the fuel of the main mixture combustion stage, subject to injection into the channel of the main mixture combustion stage through the nozzles of the fuel injectors of the main mixture combustion stage; and part of the fuel directly forms a fuel jet for direct injection into the main mixture combustion stage, and the other part hits the preliminary film plate near the internal side of the channel of the main mixture combustion stage, or both parts hit two layers of the preliminary film plates, respectively.

EFFECT: invention provides a possibility of reducing the contamination level.
