Application And Study On The DeNO_x-Technology Of Flue Gas In The Power Plant

This paper introduced the development of deNOX-Technology in foreign and domestic and detailedly expatiated on some nitrogen-oxide control technologys and their application. After the paper combined with the demand of deNOX rebuilding engineering in the powerplant and compared with the characteristic of some deNOX-Technologys, the paper put forward the optimal deNOX-process—selective catalytic reduction (SCR).SCR is the technology which is the most widely used and the reliablest gas deNOX-Technology. Its removal efficiency is up to 90%. The paper has researched the theory and reaction process, analyzed influencing factors of removal efficiency and set forth practical value of SCR.Finally, the paper carried through primary design of SCR system flow and process. And benefits of environment and economy were appraised.
