<p>Noxious flue gases issuing from a combustion process are treated by a chemical - mechanical process wherein initial condensation of at least a portion of the water vapour present, and intimate mixing of this condensation with a high concentration of alkali and/or alkali salts and the residual gases, results in scrubbing of the flue gases. A major portion of the resulting product is removed from the residual flue gas. The loss in thermal energy of the flue gases in the initial stage of scrubbing may be subsequently compensated by supplementary heating. Additional treatment includes the spraying of a basic substance such as limewash in dispersed relation into the residual flue gases, to eliminate the acidic content of the gases, and to regulate the amount of carbon dioxide in the atmosphere.</p> |
