Abstract
An arrangement for mixing fluid streams in a duct, said arrangement comprising: at least one mixing device having front side and back side and positioned within said duct through which a first major stream travels, the at least one mixing device determining a total cross-sectional area which is significantly lower than that of the duct so as to allow for the passage of said first major stream, in which the at least one mixing device is a solid plate provided with one or more protrusions extending outward from the main solid plate body.
Claims7
An arrangement for mixing fluid streams in a duct (1), said arrangement comprising:
- at least one mixing device (3) having front side and back side (3′) and positioned within said duct (1) through which a first major stream (2) travels, the at least one mixing device (3) determining a total cross-sectional area which is significantly lower than that of the duct (1)
- in which the at least one mixing device (3) is positioned within the duct (1) so that the first major stream (2) forms with the front side of the at least one mixing device (3) an incidence angle (α) of between 10° and 80°,
- wherein the at least one mixing device (3) is in the form of a solid plate comprising a main solid plate body (10) having a circular or elliptical configuration defining a circumferential arcuate edge (20) and one or more protrusions (9, 11) extending outward from the arcuate edge, the one or more protrusions (9, 11) having a triangular configuration and being located in the same plane defined by the cross section of the main solid plate body.
