Stages combustion chamber, whose full load burner also contain empty running burner

摘要

The invention relates to an annular combustion chamber comprising the axial walls (1, 2) connected by a bottom of chamber (3) and a plurality of fuel injectors placed in holes (4) passing through the bottom of chamber (3), said injectors being distributed on a pilot head (20) and on a high power head are radially spaced apart from the pilot head (20), the said combustion chamber having a general direction (11) of the gas flow. The pilot head (20) is fitted with n nozzles of idling, in the permeability p1, adapted to the idling speeds. The take-off head is equipped, in alternation, of low power injectors of permeability p1, adapted to the idling speed, and n take-off nozzles of permeability p2 p1, adapted to the state of full load. According to a view of the bottom of the chamber (3) from the inside of the combustion chamber, parallel to said direction of flow (11), the fuel injectors of permeability p1 of the pilot head (20) and of the high power head are disposed substantially in a staggered configuration.
