FIELD: power engineering.
SUBSTANCE: turbomachine combustion chamber comprises an axis of gases flow, inner and outer circular walls, joined to each other by the chamber bottom. The inner and outer walls are accordingly equipped with at least one circumferential row of primary holes and at least one circumferential row of dissolution holes. Primary holes and dissolution holes are evenly distributed on the circumference of the inner and outer walls. All primary holes of the inner wall are arranged at one and the same axial distance (D) relative to the chamber bottom. All primary holes of the outer wall are arranged at one and the same axial distance relative to the chamber bottom. At least on one of inner or outer walls dissolution holes are distributed in the first row and in at least one second row. All dissolution holes of the first row are arranged at one and the same distance along the axis (Y) of the chamber relative to primary holes of the inner or outer wall. Primary holes are arranged in the same angular position as at least some dissolution holes of the second row, and position of dissolution holes of the first and second row arranged at the angle between two serially arranged primary holes forms a pattern that repeats along the entire circumference of the considered inner or outer wall.
EFFECT: elimination of aerodynamic relation of air jets outgoing from holes of two different types, without increase of quantity of pollutant emissions, without development of negative effect at temperature distribution at the outlet from the combustion chamber, thus optimising possibilities of repeated ignition.
