<p><P>PROBLEM TO BE SOLVED: To provide a method for reducing organochlorine compounds in the exhaust gas of cement manufacturing equipment, by which the discharge amount of the organochlorine compounds such as dioxins or PCB discharged from the cement manufacturing equipment can be reduced. <P>SOLUTION: An adsorbent powder serving also as fuel is supplied into the exhaust gas generated during firing to adsorb the organochlorine compounds such as dioxins or PCB contained in the exhaust gas on the adsorbent powder, and then the adsorbent powder is collected by a bag filter B2 after adsorption and used as fuel for a combustion burner 17 during firing using a rotary kiln 18. Thereby, the discharge amount of the organochlorine compounds such as dioxins or PCB discharged from the cement manufacturing equipment 10 can be more reduced and the fuel for firing can be saved. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
