GAS INJECTION NOZZLE Russian patent published in 2000 - IPC

FIELD: supply of oxidizer to burner. SUBSTANCE: gas injection nozzle has exhaust chamber with wall and exhaust hole at exhaust end of exhaust chamber; wall is bent over curve; wall has cylindrical inner surface and outer surface embracing concentrically the inner surface; outer surface is bent over continuous curve line at exhaust end at section "l" and at exhaust hole forming sharp edge; bent section "l" has curvature radius "R" according to equation , where "l" has above-mentioned magnitude; "t" is maximum horizontal distance between inner and outer surfaces; α is angle of edge at exhaust end around exhaust hole. EFFECT: enhanced reliability of functioning due to modification of construction of nozzle. 9 cl, 1 dwg
