Abstract: The content of particulate matters discharged from the power generator units has declined greatly since the units in a coal-fired power plant is renovated to meet requirements of ultra-low emission.In view of the detection principle of the existing measurement methods for particulate matter and their application limitations to meet the requirement of ultra-low emission,a new method integrating sampling and detection is proposed.This method divides particles into two parts through bubbling.These two parts are respectively measured by laser scattering method.The feasibility of the method is verified by reference experiments.The reference error tends to be stable as the concentration of the particles increases.This method provides a basis for accurately measuring the concentration of particulate matters under ultra-low emission requirements and formulating test standards for low-concentration emission particulate matter in coal-fired power plants.
