Abstract:

The principle, layout, performance index and the engineering application of selective catalytic reduction (SCR), selective non catalytic reduction (SNCR) and SNCRSCR hybrid denitrification for coalfired 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.
