Worked Example: Industrial Boiler (100 kg/hr Fuel, 10 g/kg Factor, 8 hr/day)
An industrial facility operating an oil/gas boiler under typical manufacturing load:
💡 Environmental Takeaway: The boiler generates 1.2 kg of NOx per operational hour, accumulating 3.5 metric tons annually. Over a decade of consistent operation, the unit discharges over 35 tons of reactive nitrogen oxides.
