FIELD: machine building.
SUBSTANCE: tubular combustion chamber for a tubular-ring combustion chamber in a gas turbine at least contains, virtually, a cylindrical enclosure with a panel located in the axial direction upstream, and an outlet end located in the axial direction downstream, several burners with pre-mixing, passing in the direction upstream the said front panel and having a burner output supported by means of this front panel, for the fuel/air mixture supply to the combustion zone inside the enclosure. Up to four burners with pre-mixing are secured to the front panel, virtually, as per circle pattern. Each burner has a mixing tube to excite the vortex flow of the said fuel/air mixture. The central burner is not shown. Each burner has a cone vortex generator. Alignment of the central longitudinal axis of at least one burner with pre-mixing, secured to the front panel differs from the alignment of the central longitudinal axis of at least another burner with pre-mixing in the radial direction.
EFFECT: invention ensures the tubular combustion chamber with improved operability, easy maintenance and ecological characteristics.
