heat-exchanger technique. SUBSTANCE: radiation recuperator has outer and inner cylinders mounted coaxially forming circular clearance communicated with circular air collectors; it is additionally provided with circular L-shaped partition embracing inlet section of inner cylinder; it is located at outlet of supply collector; its horizontal surface is directed towards inner cylinder. Circular L-shaped partition has vertical perforated surface and continuous horizontal surface which forms elongated circular slot and circular clearance in lower zone of inner cylinder at preset area of flow section, thus creating jet-like turbulizing flow of air and ensuring efficiency of heat exchange due to breaking of boundary layer in zone of increased thermal stresses. EFFECT: enhanced efficiency. 2 dwg |
