Stationary combustion accounts for 32 % of the national NOx emission. Table
3.6 shows the NOx emission inventory for stationary combustion subcategories.
(OHFWULFLW\ DQG KHDW SURGXFWLRQ is the largest emission source accounting for 46
% of the emission from stationary combustion plants. The emission from
public power boilers > 300 MWth accounts for 32 % of the emission in this
subcategory.
Industrial combustion plants are also an important emission source accounting
for 14 % of the emission. The main industrial emission source is cement
production, which accounts for 37 % of the emission.
Residential plants account for 16 % of the NOx emission. The fuel origin of
this emission is mainly wood accounting for 67 % of the residential plant
emission.
2WKHU HQHUJ\ LQGXVWULHV, which is mainly off-shore gas turbines accounts for 16
% of the NOx emission.
Time series for NOx emission from stationary combustion are shown in Figure
3.10. NOx emission from stationary combustion plants has decreased by
65 % since 1990. The reduced emission is largely a result of the reduced
