Stationary combustion is the most important emission source for SO2 accounting
for 72 % 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 36
% of the emission. However, the SO2 emission share is lower than the fuel
consumption share for this source category, which is 60 %. 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 45 % of the emission.
The SO2 emission from industrial plants is 33 %, 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 36 % 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.
