Abstract

A fluid mixing apparatus for mixing a first fluid with a second fluid is provided. The fluid mixing apparatus includes a first housing, a second housing, a first actuator corresponding with the first housing, and a second actuator corresponding with the second housing. The first housing is provided with an inlet for supplying a first fluid such as water in the form of steam, and a nozzle outlet attached to a nozzle end of the first housing. The second housing is coupled to the nozzle end of the first housing and includes a inlet for supplying a second fluid such a slurry. A mixing tube, which may be slidable, is contained within the second housing for mixing the first fluid and the second fluid therein before passing the mixture out of the second housing. Alternatively, collar member may be circumferentially mounted around a stationary mixing tube contained in the second housing, or alternatively, around the nozzle outlet of the first housing. Depending upon whether the mixing tube is slidable, or where collar member is mounted if utilizing a stationary mixing tube, a circumferential gap is created between nozzle outlet and the collar member when the collar member is mounted on the mixing tube, and between the mixing tube and the collar member when the collar member is mounted on the nozzle outlet. The sliding mixing tube or collar member is made adjustable via a second actuator which is capable of adjusting the sliding mixing tube or the collar member so as to narrow or widen the gap and to control the pressure of the second fluid introduced into the mixing tube.
