Application and comparison of SCR, SNCR and SNCR/SCR flue gas denitration technology

Abstract

Abstract:

The principle, layout, performance index and the engineering application of selective catalytic reduction (SCR), selective non catalytic reduction (SNCR) and SNCRSCR hybrid denitrification for coalfired power plant have been briefly presented. Comparing the three kinds of denitration technology comprehensively, three kinds of control system configuration schemes of denitrification are provided, which can provide reference for the choice of denitrification scheme and control mode.

Key words:
