Abstract: Taking three typical cement plants in Beijing-Tianjin-Hebei region as examples, we tested the PM2.5 emissions from cement plants during normal production based on EPA 201A method. The resulted PM2.5 emission factors are respectively 0.019、0.059g/t-clinker for cooler stack, 13.272、0.206、2.909g/t-clinker for preheater stack, 0.484、0.208g/t-cement for cement mill stack, and 3.703、0.155g/t-coal for coal mill stack. This paper gives the basic data and primary conclusions of PM2.5 emissions from cement plants.
