Abstract: A dry solids separator is described for removing powdery materials from a gas stream without a substantial overall pressure drop as said stream passes through the separator. The separator consists of a plurality of mutually spaced baffle plates disposed as at an angle to the inlet of the separator. Each plate consists of a plurality of mutually spaced channel shaped baffles opening into the gas stream and defining between adjacent baffles vertical slit nozzles. The channel shaped nozzles are also staggered so that the next adjacent downstream baffle will be behind an upstream nozzle.
