The APC ash samples used in this study were taken
from a single MSWI facility located in the metropolitan
area of Tarragona (Spain). The feed stream is mainly
composed of household rubbish, with a small input from
commercial sources. With two parallel trains of 9.6 t/h
(150,000 t of MSW incinerated per year), the flue gases
are cooled through heat exchanges with a boiler and sent
to a semi-dry scrubbing system, where acid gases are neutralizing
by means of the addition of lime grout. Acid gas
scrubbing residue and fly ash particles are later captured
by a fabric filter producing 8 t/d of APC residue.
