STRAIGHT-FLOW VORTEX BURNER Russian patent published in 1995 - IPC

FIELD: power engineering. SUBSTANCE: straight-flow vortex burner has air passage 1, axial swirler 2, gas tubes 3 which are provided with gas distributors at their outlet; gas distributors have exhaust holes. Distributors are made in form of two intersecting plates 6 and 7. Plates 6 are located perpendicularly to longitudinal axis 4 of air passage 1 and at larger radial distance as compared with plates 7 which are located at inclination relative to axis 4 in the direction opposite to flow; axes of exhaust gas holes made in plates 6 are located in parallel with longitudinal axis 4 of passage 1 and those in plates 7 are located at angle of 30 to 60 deg. to plane of cross section; passage area of holes in inclined plate 7 of each gas tube 3 is about 30 to 60 percent of total passage area of all exhaust gas holes. EFFECT: enhanced efficiency. 3 dwg
