u2032 and a flow director 14 u2032 the latter of which includes an elongate cylindrical tube 32 coaxially centered in sleeve 12 u2032 to provide an annular flow space 20 u2032 between sleeve 12 u2032 and tube 32 as with rod 18 shown in fig1 tube 32 may have an outside diameter ranging from about 4 to about 5 millimeters a liquid inlet ejector 34 having an orifice 36 is provided for introducing a liquid 38 such as water in the form of a spray into the interior 40 of the tube 32 a gas 42 such as air introduced into the interior 40 of the tube 32 entrains the spray so that moistened gas 44 containing a fine mist of liquid entrained droplets is produced a high velocity flow of gas 24 u2032 which may also be moistened is directed along the annular space 20 u2032 between sleeve 12 u2032 and the outside surface of tube 32 so that it exits the nozzle 10 u2032 through sleeve open end 22 u2032 the resulting flow of gas as indicated by arrows 26 u2032 exiting the nozzle 10 u2032 is induced by the shape of head 16 u2032 in conjunction with its spacing dimension and arrangement relative to open end 22 u2032 of sleeve 12 u2032 to a turbulent flow regime.
