A hot, particulate-laden process gas stream is cooled preparatory to cloth filtration treatment thereof by conducting said stream through a venturi-shaped conduit (20) adapted to cause acceleration of the stream to a Mach number of at least about 0.25. A plurality of streams of liquid water is introduced through means (27) transversely into the process stream in the region of the throat (24) of the venturi-shaped conduit (20), the rate of total water so introduced being sufficient to cool the process stream to the desired temperature. The cooled process stream can then be conducted into a cloth filtration device (15) wherein separation of the particulate component from the gaseous component is performed. <IMAGE> |
