ABSTRACT:
A method of flue-gas cleaning comprising the separation of water-soluble substances from flue gases containing water vapor. The invention is characterized in that the flue gases are caused to be cooled by direct contact between flue gas and atomized water in two or more separation steps, where in a separation step (2) subsequent in the flow direction of the flue gases the flue gases are cooled by atomized water to a temperature, at which the water in the flue gases is condensed out, which water is collected and thereafter both recirculated for utilization in said subsequent separation step (2) and introduced into a separation step (1) prior in the flow direction of the flue gases. In said prior separation step the water is atomized and meets uncleaned flue gases, the water-soluble and potentially water-soluble substances of which thereby are solved in the atomized water. The water thus impurified is collected for further treatment.
