FIELD: machine building.SUBSTANCE: ring combustion chamber for the turbine machine contains external wall and internal wall mainly oriented axially relatively to the axis of rotation of the turbine machine, and is closed from the input side by wall of the chamber bottom essentially oriented radially. The chamber is supplied with the compressed air from the compressor via the diffuser, its output direction is shifted radially relatively to the middle axis of the combustion chamber. The wall of the chamber bottom contains holes for the cooling air supply, inclined relatively to the normal direction to the chamber bottom. Number of holes oriented radially in the direction opposite to the radial direction along which the output of the said diffuser is located exceeds the number of holes oriented radially in radial direction of the output of the said diffuser. All holes can be also oriented radially in the direction opposite to the direction along which the output of the said diffuser is located.EFFECT: relatively uniform temperature is ensured on both internal and outside walls of this chamber without increasing of the cooling air volume.10 cl, 3 dwg |
