Emisja tlenku diazotu z procesów spalania paliw w kotłach pyłowych i fluidalnych

The objective of the study was to analyze the emission of N2O during selective non-catalytic reduction of nitrogen oxides( using ammonia and urea as reducing agents) with co-removal of SO2 and NOx from the flue gases leaving pulverized-huel boilers and fluidized boilers. The concentrations of air-borne N2O were not found to create hazards to human beings ( no strict environmental regulations pertaining to that gas had been issued so far ). However,there is much likelihood that such hazards will appear in the future,if we take into account the depletion of ozone in the stratosphere and the ever increasing greenhouse effect.
