ABSTRACT:
Equipment for dispersing particulate material in a stream of gas comprises a duct to contain the stream of gas, a bluff body mounted and extending transversely within the duct to create turbulence in the gas stream, and means for introducing particulate material immediately upstream and/or downstream of the bluff body, whereby the material becomes uniformly entrained in the gas stream. The invention is of particular value for introducing alumina for dry scrubbing of HF-containing exhaust gases from aluminum electrolytic reduction cells.
