A contact reactor (6) through which a contaminated medium (5a min ) is caused to pass and into which there is introduced an absorbent (67, 68) capable of reacting with the contaminants carried by the medium, means (67, 68) being provided for mixing the medium with the absorbent. In accordance with the invention wall sections (64, 65) forming part of the contact reactor define a reactor chamber (66), into which a finely-divided liquid or a slurry is introduced and brought into contact with the flow of contaminated medium. The wall sections are heated by the flow of contaminated medium (5a min ) of the high temperature, this flow of contaminated medium passing the wall sections (64, 65) via a slot-like spacing (63) in a manner to deliver heat to the wall sections, whereafter the contaminated medium passes into the reactor chamber (66). Turbulence-generating means (70) are arranged downstream of the reactor chamber (66), while a means for supplying powdered absorbent (70) is arranged downstream of the turbulence-generating means (70). |
