KOLDING MUNICIPAL WASTE

INCINERATION PLANT
General aims:
To obtain a significant reduction in dioxin emissions by reasonably simple
means.
Description:
In May 2002, ADIOX
®
tower packing material was installed in two ten-year
old scrubbers at the Kolding municipal waste incineration facility in Denmark.
The heat and power plant incinerates some 100,000 tons of waste annually,
producing approximately 200 GWh of heat and 50 GW of electricity.
For development purposes, a pilot plant was simultaneously positioned in series
with one of the scrubbers. The pilot is equipped with ADIOX
®
tower packing
material as well as an ADIOX
®
demister.
The furnaces generate some 80,000 Nm
3
/h (line 2) and 35,000 Nm
3
/h (lines 3 +
4) of flue gas respectively.
The extent of the ADIOX
®
installation varies between the two lines. Results
from line 2, where the major part of the ADIOX
®
is installed, show a 79%
reduction in dioxin levels. This is a mean figure from measurements made
during the first six months of operation. In the various measuring campaigns
carried out, the dioxin concentrations ranged from 1 to 5 at the inlet, and down
to 0.2 to 1 at the outlet of the line 2 scrubber. Much lower levels have been
measured at the outlet of the pilot scrubber.
