On the Issues of NOx as Greenhouse Gases: An Ongoing Discussion…

Nitrogen oxides (NOx = NO + NO2) emitted from a stationary combustion chamber (including waste to energy plants) or engines cause numerous undesirable environmental effects. These include negative influences on human and animal health, detrimental effects plants vegetation, acid rain, smog. are commonly accepted by the scientific community. However, impact of NOx greenhouse effect (GHE) is not generally In this paper, issue GHE discussed, it was analyzed explained that an indirect gas (GHG). complex process affected different parameters (cooling warming nature possible). It has been estimated stationary, ground-placed sources (such as boilers furnaces) have little compared CO2 other direct GHGs. The contribution in emission all GHGs less than 3%. incineration co-incineration were especially considered analyzed. smaller (capacity range 1 ÷ 5 MW) gives more benefits environment due decrease standards when share increases.
