Question

How to calculate theoritical NO_x and SO₂ (mg/Nm³) in gases at coal fired power plant, if known :

Coal Calorific Value = 4500 kcal/kg
Fuel consumption = 180 t/h
Excess air = 18%
Oxygen in exhaust gases = 5%
Flue Gas Temperature in exhaust gases = 135 deg C

Carbon Content = 30.110
Hydrogen Content = 3.610
Oxygen Content = 9.850
Sulfur Content = 0.330
Nitrogen Content = 0.700
Ash Content = 5.740
Moisture Content = 32.530

(Information : For value of SO₂ in our CEMS around 490 to 530 mg/Nm³)

Thank you!
