Business Field

M·SNCR DeNOx technology

This process uses NH℃ as a reductant to convert NOx in flue gas into N2 and H2O in a high temperature environment. It is suitable for the system that has a flue gas temperature window above 800 and a low DeNOx efficiency.

Technical Advantages

  • The reaction temperature should be above 800°C;
  • Reconstruction of furnace is simple, requiring a small quantity of works;
  • It has a DeNOx efficiency of 40~60% and can be used together with other DeNOx processes to achieve a higher efficiency and reduce the investment cost.
