Abstract
A Venturi apparatus and method used with a cyclone separator to separate particulates, fumes and waste gases from gas, as air. The apparatus has a housing having a generally rectangular chamber through which the gas and particulates flow. The housing has converging side walls forming an elongated rectangular Venturi throat. Plates movably located in the chamber between the side walls are spaced from each other to control the length of the Venturi throat. Controls connected to the plates are operable to move the plates relative to each other to change the length of the Venturi throat. The width of the Venturi throat is determined by the spacing of the side walls and is not changed by movement of the plates.
