Abstract
Abstract A smoke consuming device having a vertically extending passageway and an open lower smoke-intake end to be secured to the smoke discharge end of a stack or the like; a horizontally positioned deflector spaced within the upper open end of said passageway cooperating with the sides of said passageway at the open upper end to define an annular discharge aperture around the outer periphery of said deflector, said passageway having downwardly and inwardly inclined walls extending from said upper open end of said passageway to a restricted-diameter throat spaced below said deflector and coaxial with said discharge aperture, and fuel discharge openings around said inclined wall spaced below the level of said deflector and directed toward the latter arranged to provide a substantially continuous annular flame extending across the path of smoke to said annular flame when said fuel is discharged through said openings into said passageway under pressure and is ignited.

A SMOKE CONSUMING DEVICE FOR POSITIOING ON THE DISCHARGE END OF A STACK COMPRISING; A. A BODY HAVING A VERTICALLY EXTENDING PASSAGEWAY WITH A CIRCULAR OPEN UPPER END AND A CIRCULAR OPEN LOWER END, B. THE WALL OF SAID PASSAGEWAY TAPERING INWARDLY FROM ITS OPPOSITE OPEN ENDS TO AN ANNULAR THROAT OF RESTRICTED DIAMETER INTERMEDIATE SAID OPEN ENDS, C, AN OUTER WALL SPACED OUTWARDLY OF THE WALL OF SAID PASSAGEWAY AND EXTENDING THEREAROUND, SAID OUTER WALL AND SAID WALL OF SAID PASSAGEWAY BEING CONNECTED AT SAID UPPER AND LOWER ENDS TO PROVIDE AN ANNULAR FUEL CHAMBER BETWEEN SAID OUTER WALL AND THE WALL OF SAID PASSAGEWAY, AND THE ANGLE OF THE UPPER PORTION OF THE WALL OF SAID PASSAGEWAY DISPOSED BETWEEN SAID THROAT AND ITS UPPER OPEN END BEING APPROXIMATELY 45* RELATIVE TO HORIZONTAL, D. A HORIZONTAL, CIRCULAR DEFLECTOR PLATE COAXIAL WITH SAID UPPER OPEN END SPACED WITHIN THE LATTER COOPERATING WITH SAID OPEN UPPER END TO DEFINE AN ANNULAR DISCHARGE APERTURE FOR PRODUCTS OF COMBUSTION AND MEANS FOR POSITIONING THE LOWER END OF SAID BODY ON A STACK FOR PASSAGE OF SMOKE FROM THE LATTER INTO THE LOWER END OF SAID PAASSAGEWAY, E, MEANS FOR SUPPLYING FUEL TO SAID CHAMBER, F. A PAIR OF HORIZONTALLY DISPOSED AXIALLY SPACED ANNULAR ROWS OF SPACED OPENINGS FORMED IN IN SAID UPPER PORTION OF THE WALL OF SAID PASSAGE WAY DIRECTED AT AN ANGLE OF APPROXIMATELY 45* RELATIVE TO HORIZONTAL AND TOWARD THE UNDERSIDE OF THE OUTER MARGINAL PORTION OF SAID DEFLECTOR PLATE PROVIDING FLAME OPENINGS FOR DIRECTING THE FLAMES OF IGNITED FUEL DIRECTED IN AND SAID OUTER MARGINAL PORTION OF SAID DEFLECTOR PLATE, G. TTHE INDERSIDE OF SAID DEFLECTOR PLATE BEING FORMED WITH A RECESS EXTENDING TO SUBSTANTIALLY THE OUTER OF EDGE OF SAID DEFLECTOR PLATE, AND A DEPENDING FLANGE AROUND SAID PLATE AT ITS OUTER EDGE, H. THE RATIO BETWEEN THE TOTAL AREA OF SAID CIRCULAR APERTURE AND THE AREA WITHIN SAID THROAT BEING APPROXIMATELY 1.8 TO 1.
