combustion AND FUELSNITROGEN OXIDES FORMATION in combustionprocessesCOMBUSTION AND FUELSNITROGEN OXIDES FORMED DURING COMBUSTIONN2O - nitrous oxideNO - nitric oxideNO2- NITROGEN dioxideN = 14, O2=16, NO = 30, NO2= 46 combustion AND FUELSCONTRIBUTION OF PARTICULAR NITROGEN OXIDES IN TOTAL NOXPRODUCTION the biggest contribution has nitric oxide (NO) its content in flue gas is in the range of: 100 1000 mg/m3 next is NITROGEN dioxideNO2in proportion 5-10% of NO its content in flue gas is in the range of: 10 100 mg/m3 N2O has the least contribution: its content in flue gas is in the range of: 1 10 mg/m3 combustion AND FUELSWHAT DOES NOXMEAN ? combustion AND FUELSDEFINITION OF NOXNOX means the sum of NO and NO2contents in flue gas recalculated on NO2 NOx= NO + NO2(expressed in NO2) combustion AND FUELSUNITS OF NOXCOMBUSTION AND FUELSU nits of NOxcontent in flue gas mg/m3 ppm (emission) g/m3 (imission) g/GJRemarks: 1.
COMBUSTION AND FUELS RATE OF NO X FORMATION via ZELDOVICH MECHANISM It show s that the Zeldovich mechanism become s important when the temperature reach es the range of1600-1800 K.
