<p><P>PROBLEM TO BE SOLVED: To provide a method and an apparatus for mixing two or more fluid streams causing variation of flow rate. <P>SOLUTION: In the method and apparatus for mixing two or more fluid streams, the gaseous streams are combined in an inlet chamber and thereafter repeatedly accelerated and decelerated in one or more of stages, and a value of a maximum linear velocity of the accelerated combined gaseous stream is maintained in each step within a range of mass flow rates of the gaseous streams. The apparatus comprises a body with a seat; a spindle with a plug installed in the seat, and the seat and plug have a plurality of conical surfaces forming conical annuli as many as the conical surfaces. The spindle is able to move the shaft in the seat in the axial direction during the mixing. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
