Abstract
A fluid manifold (41) comprises two annular chambers (42 and 46) in flow series and having a barrier (45) therebetween. A fluid is fed into the first larger annular chamber (42) and circulates circumferential therethrough before being passed through a plurality of apertures (44) in the barrier (45) to the second smaller annular chamber (46). The fluid circulates circumferentially through the second chamber (46) in the opposite direction prior to its discharge through apertures (50) in a final barrier (48). The apertures (50) in the final barrier (48) decelerate the fluid discharging therefrom to enhance mixing of air with the fluid downstream of the manifold (41).
Claims14
A fluid manifold comprising a plurality of annular chambers arranged substantially concentrically in flow series with a barrier between each chamber and a subsequent chamber, means to supply a fluid into a first one of said annular chambers comprising at least one pipe arranged at an angle to the first one of said annular chambers such that the fluid inflows circumferentially through the first one of said annular chambers to produce a circular flow through the first one of said annular chambers before being passed through a barrier to the next annular chamber, each barrier having means to supply a fluid into a respective annular chamber comprising at least one aperture arranged at an angle to the respective annular chamber such that the fluid inflows circumferentially through each annular chamber to produce a circular flow through each annular chamber prior to its discharge through a final barrier which changes the velocity of the fluid in flow discharging therefrom.
