D10.14 extractive dust monitoring system is a high temperature heating extractive dust monitor, based on years of dust detection technology research and development process. Different from normal in situ scattering dust monitors, D10.14 uniformly samples dust in the flue (stack) to the high temperature heat tracing dust measuring module to measure. Its detection limit reaches 0.05mg/m3. It has features of no moisture influence and high accuracy. It is applicable for ultra-clean emissions, low temperature and high humidity flue gas situation after wet deSOx, meet the coal-fired power plant air pollutants emission standards.
