Abstract:
Apparatus for mixing steam and water and delivering a stream of heated water, comprising:a tube extending along an axis and having an axial opening at one end;means for directing water into the interior of the tube and for establishing a first vortex of water circulating about said axis, both within the tube and beyond the axial opening;means for directing steam in a second vortex surrounding the tube, circulating about said axis and extending beyond said one end of the tube;means for directing the vortices into contact with each other, whereby the water and steam mix together to produce a stream of heated water, andmeans, responsive to the temperature of the heated water in said stream, for regulating the flow of steam through said directing means, and maintaining the heated water at a substantially constant temperature.
