G. Mininni et al., Influence of organic chlorine on emissions from sludge incineration by a pilot fluidised bed furnace, WATER SCI T, 42(9), 2000, pp. 243-250
To demonstrate that sewage sludge incineration could be a safe operation if
well conducted and that hazardous compounds could also be disposed of with
out problems in sludge incinerators plants, a research program has been set
up by the Italian Water Research Institute on a demonstrative scale plant
where a completely circulating fluidised bed furnace and a rotary kiln furn
ace can operate alternatively. in this paper results of tests performed by
a fluidised bed furnace on sewage sludge spiked with highly chlorinated com
pounds under different operating conditions are presented. A deep investiga
tion on micropollutants formation has been made at different sampling point
s: before and after bag house filter, and at the chimney. The experimental
data show that concentrations of PCDDs+PCDFs (TE) and of PAHs do not strict
ly depend on the operation of the afterburning chamber and that a complete
compliance with the European and Italian standards on the emissions were al
ways achieved even in the most critical conditions investigated.
