<p><P>PROBLEM TO BE SOLVED: To provide a method and a device for waste liquid combustion processing capable of effectively achieving the efficient detoxification of various industrial waste liquid, improving the fuel economy, inhibiting the generation of harmful substances such as nitrogen oxide, and reducing an exhaust gas. <P>SOLUTION: A low hydrous fuel oil emulsion is produced by injecting the water to a gel for emulsion prepared by adding a surface active against to the fuel oil, and high hydrous fuel oil emulsion to which the water is injected, and the waste-mixed fuel oil emulsion to which the treated waste liquid is added, are produced on the basis of the low hydrous fuel oil emulsion. The combustion of the high hydrous fuel oil emulsion is started when furnace temperatures of a primary combustion furnace and a secondary combustion furnace reach near 800°C, and the combustion of the waste liquid-mixed fuel oil emulsion is performed for the combustion of the high hydrous fuel oil emulsion in the primary combustion furnace, when the furnace temperature reaches near 1100°C. The combustion exhaust gas generated in the primary combustion furnace is sent to the secondary combustion furnace for the further combustion of emulsion. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
