Abstract: As a technology to achieve ultra-low NOx emissions, selective catalytic reduction (SCR) has been gradually applied in the field of waste incineration.The denitrification efficiency and service life of SCR catalyst may be affected by many factors, such as flue gas temperature, SO2, H2O and soot.After deacidification and dust removal, waste incineration flue gas has characteristics such as low temperature, low acid, low dust, low heavy metal content and high moisture content.It is found that the temperature of flue gas, SO2 and water all have large impact on the denitrification efficiency and service life of SCR catalyst, of which SO2 has the biggest impact.Meanwhile, the catalytic activity and sulfur resistance of SCR catalyst itself are also key factors affecting the denitrification results.
