FIELD: combustion chambers. ^ SUBSTANCE: ring combustion chamber comprises front device, a number of mixing devices, and inner and outer housings of combustion chamber that are composed of the front and back sections. The front sections of the inner and outer housings of the combustion chamber define precombustion chamber diffuser, and their back sections lined with the heat-resistant plates define the flame tube of the combustion chamber. The walls of the precombustion chamber diffuser are step and provided with steps directed counter air flow. The steps are provided with openings that connect the precombustion chamber diffuser with the space between the heat-resistant plates and back sections of the outer and inner housings of the combustion chamber. The front device is made of perforated shield provided with openings for mixing devices and supplying additional air. The shield is secured within the butt between the front and back sections of one of the housings of the combustion chamber with the use of bolts for permitting free radial thermal expansion in the butt of the front and back sections of the second housing of the combustion chamber. ^ EFFECT: enhanced efficiency. ^ 1 cl, 1 dwg |
