In this paper, four units of a power plant are taken as the research object, and the air pollutant emission performance standards, equipment installed economic efficiency, operational economic efficiency and energy saving potential of four units using different technical methods for ultra-low emission transformation are analyzed. Take unit 4 as an example, the ultra-low emission operation cost is discussed. The results show that the operation performance, stability and reliability of some units of low-temperature economizer need to be improved; the K values of different ultra-low emission technology methods were between 7.6∼12kW/MW. The installation of a low temperature economizer allows the wet desulfurization facility to have a greater water saving capacity.
