Nitrogen oxides NOх (NO + NO2) are produced as a result of combustion of all types of organic fuels in the boilers of TPPs. Nitrogen from air and nitrogen-containing components of the organic fuel mass are sources of nitrogen oxides.
Thermal NOх (mechanism of Zeldovich) and fast NOx (mechanism of Fenimore) are formed from air nitrogen. Fuel NOx are formed from nitrogen of the fuel (coal, oil) associated with organic mass.
