It is important to understand how these pollutants from coal-fired thermal power plants disperse in the ambient atmosphere. This study examines the air pollution condition at a proposed TPP and applies an air quality model, the EPA approved dispersion model of AERMOD,to predict the ambient air pollution concentrations resulted from different emission scenarios. The stack emission rates from the power plant were calculated to provide the input emission data for the modeling. The meteorology data were taken from MM5 model, the prognostic meteorology model for 2008 year.Ground level concentrations of pollutants including oxides of nitrogen (NOx), oxides of sulfur (SOx),particulate matter (PM) were estimated by the model under three fuel-control devices scenarios. The results show that if coal is used as the main fuel with the control devices of ESP,Sea-water FGD and Low NOx Burner then only PM10 and SO2 would meet the Vietnamese national ambient air quality standards and WHO ambient air quality guidelines. Only when SCR is installed for NOx emission control are all 3 pollutants would meet the standards. If natural gasis used as the main fuel in combination with low-NOx burner then the emission of PM10 and SO2 would largely eliminated. The ambient air levels of all 3 pollutants would be well below the standards. Under all 3 scenarios the levels simulated for the populated areas and sensitive areas were found below the standards suggesting insignificant impacts from the proposed power plant. The model results under different emission scenarios can serve as the basis to suggest the emission control measures to improve the air quality in the study area A research study submitted in partial fulfillmentof the requirements for the degree of Master of Engineering (Professional)inEnvironmental Engineering and Management Research Studies Project Report (M.Eng.) - Asian Institute of Technology, 2012 Coal-fired power plants Environmental aspects Vietnam Air Pollution Vietnam Environmental impact analysis Vietnam Asian Institute of Technology. http://203.159.5.9/ait-thesis/detail.php?q=B01366 http://203.159.5.9/ait-thesis/detail.php?q=B01366 140618 20260817162308.0
