| Abstract: | A real\|time monitoring device of particulate emissions in stack,which is based on light scattering theory is presented.A semiconductor laser is used as light source in the device and four photodetectors are used to measure the incident light intensity,emerging light intensity and the light scattering energy of two forward solid angle respectively.All collected signals are sent to a microcomputer for data processing.This device can be used for performing continuous and on\|line measurment of mass concentration and particle size distribution of emissions from a stack. |
