Single Soot Particle Interference on Measuring SO₂ Concentration Using NDIR

Abstract:

The non-dispersive infrared absorption method (NDIR) is one of the important sulfur dioxide concentration measurement methods. If the soot particles are in the measurement light path, the original measurement light intensity is attenuated because of the soot particles absorption and scattering and the sulfur dioxide concentration is increasing, so the accuracy of the sulfur dioxide concentration is decreased. The single soot particle interference caused by the dissipative and the non-dissipative soot scattering and absorption is discussed in the paper. The numerical simulation results show that the sulfur dioxide concentration measurement accuracy is related to the soot particle diameter. The solution method is brought out and the measurement accuracy can be improved.
