ABSTRACT:
A process and an apparatus for the cleaning of combustible gases, particularly gases emitted in steel making plants, in which the gases are passed through a collecting duct together with additional air at conditions such as to cause the combustion of the combustible components of the gas with a reduced flame length, the said air being supplied as a double feed so as to give a protecting effect of the duct inner walls, and then the gases are saturated with water and washed, the saturation taking place by a countercurrent flow of the gases and of the saturating water, and the washing takes place by means of a Venturi scrubber, outside of the saturating tower and in which the saturated gases are recycled to the saturating stage, a pre-separation of liquid particles taking place downstream of the Venturi scrubber and upstream of the saturator, and lastly the gases are discharged to the atmosphere.
