Abstract

Abstract: Hybrid SNCR-SCR denitrification technique is a new and mature process which combines the higher efficiency of SCR and the lower cost of SNCR. The characteristics of hybrid SNCR-SCR de-NOX process, and compares it with SCR process and SNCR process technically and economically ware introduced. It has been certificated by the practice that the hybrid SNCR-SCR de-NOX process can keep high efficiency with lower coast by eliminating the ammonia injection grid (AIG) and decreasing catalytic volume, therefore it’s a flue gas treatment technology on which should be pay attention.

Key words: hybrid SNCR-SCR denitrification technique, application
