Abstract
The burner for a plurality of fluid streams provides a discharge nozzle on the end of a fuel conduit; the fuel conduit is surrounded by an air or gas conduit; in the space between the inner wall of the air conduit and the outer wall of the fuel conduit, an annulus is positioned; the annulus has a bluff downstream end in general registration with the end of the fuel conduit and creates a toroidal turbulent eddy of air or gas that enhances combustion without materially accelerating the atomized fuel.
Claims1
A burner for a plurality of fluid streams comprising,
- (a) a first conduit for fuel,
- (b) a nozzle on the end of the first conduit, to discharge atomized fuel,
- (c) a second conduit for air or gas surrounding the first conduit,
- (d) an annulus in the second conduit,
- (e) the annulus spaced away from the first and second conduits,
- (f) a flat, downstream bluff end on the annulus disposed perpendicular to the longitudinal axis of the first and second conduits,
- (g) the downstream bluff end of the annulus disposed in general registration with the nozzle, whereby a toroidal turbulent eddy of gas and fuel is created,
- (h) a third conduit for air or gas surrounding the second conduit,
- (i) a second annulus on the third conduit,
- (j) the second annulus spaced away from the second and third conduits,
- (k) a flat downstream end on the second annulus, perpendicular to the longitudinal axis of the first, second and third conduits,
- (l) the downstream end of the second annulus disposed in general registration with the nozzle, whereby the second annulus further contributes to the toroidal, turbulent eddy of gas and fuel.
