FIELD: gas turbine engine building.
SUBSTANCE: invention can be used in the construction of combustion chambers (CC) of gas turbine engines (GTE) of earth application working with natural gas. Technical effect is reached in low emission burner containing body with nozzle, swirler with hollow blades with holes for fuel supply into the general zone, bluff central body with holes for fuel supply into the standby zone and holes of air supply to the standby zone, pin with fuel supply channels into general and standby zones and air inlet channel before the swirler, cocurrent air step swirler vane with height from 15 to 20% of the channel height.
EFFECT: ensures wide range of stable burning of CC and low emission level of NOx and CO during engine nominal operation due to reduction of fuel.
