Monodispersion Soot Position Interference Mechanism on Measuring the Soot Concentration Using the Scattering Method

The soot emission concentration of the stationary pollution sources is one of the important measurement parameters of the atmosphere pollution CEMS. The monodispersion soot position can affect the original measurement light intensity and reduce the soot concentration measurement accuracy. To reduce the monodispersion soot particles position interference, the monodispersion soot particles position interference mechanism is studied in this paper. The difference angle range scattering light intensity of the monodispersion soot is calculated. The numerical simulation results show that the difference soot position can reduce the soot concentration measurement accuracy. The solution method is brought out and can improve the measurement accuracy.
