Abstract
A method of removing acid gases from hot flue gases wherein the flue gas is fed through a pipe (3) and up through a tubular reaction chamber (1) having a diverging bottom wall (2) which causes a rapid reduction in axial velocity. Further flue gas is introduced tangentially through a pipe (5) to produce a rising swirling stream of flue gas, in which a powdery absorption agent, that has been introduced through an inlet (4), is entrained. The agent reacts with the acid gas to produce powdery reaction products which are subsequently removed in separators (7,7').
