Abstract

Exit gases from pyro-metallurgical processes are cooled and cleaned and condensible vapours in the gases condensed by flowing them tangentially through a hot-gas cyclone the interior walls of which are irrigated with a molten metal, alloy or salt which serves to remove gas-borne liquid and solid particles by impingement on the wetted walls of the cyclone.
