Estimation of environmental pollutants using the AERMOD model in Shazand thermal power plant, Arak, Iran

This study aimed to estimate the environmental pollutants emitted from a thermal power plant's chimney. The power plant emission distribution during the 8-hour and average annual periods was modeled using the AERMOD and compared with national and international standards from December 22 2019 to September 21 2020. When the use of mazut fuel, the PM10, NOX, CO concentrations as fuel burn are less than the national and international standard. The maximum CO concentration at the 8-hour time interval is 0.15, which indicates power plants have a smaller share of CO emissions in an urban environment.

Automated summary

This study estimated the environmental pollutants emitted from a thermal power plant's chimney and compared them with national and international standards. The results showed that when using mazut fuel, the concentrations of PM10, NOX, and CO emitted from the power plant were lower than the standards.
