Stationary combustion is the most important emission source for SO2
accounting for 73 % of the national emission. Table 3.5 presents the SO2
emission inventory for the stationary combustion subcategories.
(OHFWULFLW\ DQG KHDW SURGXFWLRQ is the largest emission source accounting
for 43 % of the emission. However, the SO2 emission share is lower than
the fuel consumption share for this source category, which is 61 %. This
is a result of effective flue gas desulphurisation equipment installed in
power plants combusting coal. In the Danish inventory, the source category
(OHFWULFLW\ DQG KHDW SURGXFWLRQ is further disaggregated. Figure 3.8
shows the SO2 emission from (OHFWULFLW\ DQG KHDW SURGXFWLRQ on a disaggregated
level. Power plants >300MWth are the main emission source,
accounting for 52 % of the emission.
The SO2 emission from industrial plants is 26 %, a remarkably high
emission share compared with fuel consumption. The main emission
sources in the industrial category are combustion of coal and residual
oil, but emissions from the cement industry is also a considerable emission
source. Ten years ago SO2 emission from the industrial category
only accounted for a small part of the emission from stationary combustion,
but as a result of reduced emissions from power plants the share
has now increased.
Time-series for SO2 emission from stationary combustion are shown in
Figure 3.9. The SO2 emission from stationary combustion plants has decreased
by 93 % since 1990. The large emission decrease is mainly a result
of the reduced emission from (OHFWULFLW\ DQG KHDW SURGXFWLRQ, made
possible due to installation of desulphurisation plants and due to the
use of fuels with lower sulphur content. Despite the considerable reduction
in emission from electricity and heat production plants, these still
account for 43 % of the emission from stationary combustion, as mentioned
above. The emission from other source categories also decreased
considerably since 1990. Time-series for subcategories are shown in
Chapter 3.2.3.
