Apparatus for and a method of processing particulate gas and fumes.

摘要

An apparatus for processing gas from a coke oven comprises a heat exchanger through which the gas passes prior to entry to a fabric filter plant at a reduced temperature in excess of 130 DEG C, preferably at 150 DEG C or more, and a precoat supply system adapted initially to feed a precoat of at least limestone/dolomite or coke or admixtures thereof for the filter fabric into the heat exchanger gas inlet and/or the fabric filter plant and thereafter the said precoat mixed with particulate recovered from the heat exchanger and fabric filter.
