Abstract

Particle sampling and measurement methods and systems in China and abroad were concluded and compared,the measurement principles,configurations and characteristics of sampling systems,applicable scopes,particle transition and loss were analysed.A reliable ultra-low concentration particle measurement solution was achieved to meet the situation at the testing spots after flue gas desulfurization systems (FGDs) and wet electrostatic precipitators (WESPs) where the flue gas is in high humidity,which guarantees accuracy and reliability of particle emission concentration analysis and flue gas purification equipment operation assessment.

Key words： ultra-low emission particle measurement PM_2.5 sampling system coal-fired power plant
