The emissions of selected air pollutants of pulverized coal-fired power plants, namely Uong Bi and Quang Ninh 1 were studied. Existing sampling ports of the plants were used for the monitoring. PM was collected isokinetically using a stack sampler, Metlab (Sweden). The concentrations of gaseous pollutants were measured by a combustion gas analyzer, Quintox KM - 9106 (UK). The emission factors of PM, CO, SO2 and NOx for UB, on the basis of coal consumed (g/kg) and electricity produced (g/kWh) are 4.91 and 3.45
3.84 and 2.69
18.91 and 13.25
5.86 and 4.11 respectively. For QN1, the emission factors of PM, CO, SO2 and NOx are 0.16 and 0.07
0.65 and 0.30
0.18 and 0.08
3.17 and 1.46 respectively. Emission factors obtained in this study can be used for the air quality management of these plants in particular and of the thermal power sector in general.
