ABSTRACT:
The subject invention relates to a method for reducing the concentration of NOx formed in fossil fuels combustion process to harmless N.sub.2 discharged in the combustion effluents and process comprising the step of interjecting hydrazine and/or hydrazine compounds into the fuel combustion reaction zone mixture of a fossil fuel fired combustion apparatus or combustion device, to inhibit the mechanism of NO formation in the fuel combustion reaction zone and reduce formed NO present in the fuel combustion reaction zone mixture to N.sub.2 in reaction with hydrazine and/or hydrazine compounds interjected into the fuel combustion reaction zone.
