| Research Abstract |
The inhibition of formation of toxic substances such as dioxins and chlorinated benzenes is indispensable in order to optimize the energy utilization in municipal waste incinerations. To inhibit the formation of toxic substances, the combustion after the pre-dehydration treatment of a municipal waste is important, and the prevention to adhere the fly carbonaceous matters on wall in flue around 300 ℃ , whose method is the pressurization with gas spray from porous wall in flue, is more effective. On the other hand, water vapor accelerates the formation of toxic substances because water vapor strongly enhances the chlorination of precursor of toxic substances on the porous refractory of SiO_2-Al_2O_3 system at 300 ℃.
