FIELD: machine building.
SUBSTANCE: combustion chamber assembly contains combustion chamber, primary combustion chamber, secondary combustion chamber and damping device. The combustion chamber assembly is intended to reduce pulsations of the combustion chamber occurred inside the gas turbine unit, essentially containing at least one compressor, primary combustion chamber, connected downstream the compressor, and hot gases from the primary combustion chamber enter the secondary combustion chamber. The dampening device contains at least one flame tube of the combustion chamber, containing holes for mixing air. At least one of holes for the mixing air is made in form of dampening manhole connected with the dampening volume, that is part of the connecting channel made with possibility of continuation between the air discharge chamber of the compressor and combustion chamber assembly. At least one of holes for the mixing air is made with possibility of air injection in hot combustion products between the primary combustion chamber and secondary combustion chamber.
EFFECT: reduced CO2 discharges and assurance of stable combustion.
