Vřesová K4* (Czech Rep.) - 1x325 t/h
Ecologization of the boilers K1 up to K5 will ensure reduction of nitrogen oxides (NOx) emissions to the guaranteed value of 200 mg/Nm3 at 6 % O2 in dry flue gas. Reduction will be achieve by modification of the combustion process and by application of selective non-catalytic reduction.
Settling the emission issue in the boilers K1 up to K5 will result in achieving the emission limits required by the new EU directive coming into effect in 2016.
The emissions NOx will be gradually reduced in the boiler K2 in 2010, K3 in 2011, K4 in 2012, K5 in 2013 and K1 in 2014.
