【 摘 要 】

With the transformation of ultra-low emissions and the increasingly stringent emission standards for environmental pollutants, power plants have to seek the best economic operation mode to meet the requirements of the policy. In this paper, taking a power plant in North China as an example, the economic operation mode of denitration and desulphurization under the new local policy is considered. When the emission concentration of NOX at the outlet of selective catalytic reduction reactor is controlled in 20 mg/Nm3 and 15 mg/Nm3, the power plant has a significant economic effect. However, the desulfurization system is inappropriate if reduces the SO2 emission concentration.
