Abstract
A mixer-injector having a carrier stream inlet, an additive stream inlet and an outlet. Between the carrier stream inlet and the outlet there is a throat means having an axis of flow, a constricting portion of decreasing diameter, an expanding portion of increasing diameter, and a throat portion interconnecting them. Port means discharges from the additive stream inlet into the throat portion adjacent to the constricting portion. In the preferred embodiment, skew-oriented channel means is carried by the wall of the expanding portion.
