ABSTRACT |
As one of efforts of investigating considerable operating parameters for actual dust collecting processes of MSW incinerators, fly ash was collected and classified by particle size to find any relations between ash components including catalytic components and dioxin levels. There were no prevailing components to critically influence dioxin levels in the actual process. Another operating variables including residence time of particles and differential bag pressure were varied to observe effects on dioxin level change. Experimental results show that dioxins concentration increases as particle residence time increases and it also tends to increase as differential bag pressure increases in SDA/BF process. It indicates that the time particulate matters stay in the collection process may be an important parameter for dioxins generation as well as temperature, gas residence time, catalytic constituent. |
