FIELD: power industry.
SUBSTANCE: burner assembly with varying kinetic energy for individual spraying of fuel gas and an oxidiser to a combustion zone, which includes at least two fuel gas channels, at least one oxidiser channel and a fuel gas distributor, in which at least two fuel gas channels include an internal fuel feed pass forming an internal outlet fuel gas hole, and an external fuel feed pass forming an external outlet fuel gas hole. The above said internal and external fuel feed passes are located coaxially; with that, the above fuel gas distributer includes the first fuel gas chamber in connection as to fluid medium to the internal fuel feed pass at least of two fuel gas channels, and the second fuel gas chamber in connection as to fluid medium with the external fuel feed pass at least of two fuel gas channels.
EFFECT: lower emissions of nitrogen oxides to atmosphere.
