| Abstract： In recent years, frequent haze has made PM2.5 become a public hotspot. PM2.5 control has been added to the 2012 release “ambient air quality standard.” Currently flue gas pollutant control technology does not easily remove PM2.5. Developing Flue Gas Pollutant Deep-removal Technology (DRT) for coal-fired power plants for deep-removing pollutants such as PM2.5, SO2, SO3, and heavy metals, is an urgent problem. Based on the analysis of the necessity and existing problems of developing DRT suitable for China, this study focused on PM2.5 removal technology, low NOx emission of ultra supercritical boiler under all load conditions, and the adaptability of SCR working temperature. Finally, the flue gas pollutant removal system at a 2×660MW supercritical power plant was introduced, and the roadmap for developing DRT for 1,000MW ultra supercritical units was analyzed. |
