Survey to develop standards on air polluting emissions from the power plants

Rapid urbanization and industrialization cause increase in energy consumption and generate air and water and soil pollution from the particulate emission into the atmosphere caused by fuel combustion in energy production. There are no emission standards and norms for these polluting substances, and thus, environmental monitoring and inspection organizations cannot objectively measure the impact of air pollution, and effectively control it. Coal-fired power plants release nitrogen oxides (NOx), carbon dioxide (CO), sulfur dioxide (SO₂) and fly ashes as like pollutant compounds during the operation time. Therefore, there is a need in scientific based methods for measurement of air pollutants in order to establish standards for air pollution monitoring and controlling. This work researched some air pollutant substances, and proposed methods for establishing monitoring and measurement standards. This study have proposed standards on the content of the polluting compounds (fly ashes, CO, NO₂, SO₂) based on tests and studies made at the boiler of type BKZ-420-140 of the thermal power plant #4, Ulaanbaatar city, Mongolia.
