Multidispersion Soot Interference Mechanism on SO₂ Concentration Using NDIR

Abstract:

NDIR is one of SO₂ concentration measurement methods. SO₂ concentration can be figured out through measuring the infrared light intensity changing. The light intensity can be attenuated by the particles, so the SO₂ concentration is increased. To solve the particles interference, the multidispersion particles interference mechanism is established. Particles characteristic parameters which interferes the SO₂concentration include the dissipativity, concentration, average size and size distribution parameters. Simulation results give the relationship between the SO₂ concentration and particles characteristic parameters. The method to reduce the interference of the SO₂ concentration is brought out and the measurement accuracy can be improved.
