Method for purifying exhaust gases from acidifying compounds, which exhaust gases are exposed to an alkaline compound such as Ca(OH) 2 which is reacted with and therefore neutralizes the acidifying compounds. The invention is characterized in that ash comprising CaO in a first step is mixed, in a container (101), with water, but not with the exhaust gases, and is heated so that CaO is transformed into Ca(OH) 2 , and in that the hence formed Ca(OH) 2 in a second step is reacted with, and therefore neutralizes, the acidifying compounds in the exhaust gases. |
