Method and apparatus for controlling the pressure of gases flowing through a conduit

摘要

Method and apparatus for the control of velocity and pressure of hot gases flowing through a conduit wherein generally spherically shaped objects of refractory material are disposed within such conduit during the operation thereof to provide a constriction of the cross-sectional area of the conduit through which the gases are flowing. A particular embodiment of apparatus employed in the present invention comprises a pair of generally spherically shaped refractory objects secured together by means of a length of steel cable.
