Study on denitrification technology improvement of a coal-fired power plant

摘要

The nitrogen oxides emission concentration of a coal-fired units exceeded national standards. This paper analyzed the problem of the denitrification equipment, the denitrification process was transformed with low NO_X combustion and hybrid SNCR & SCR denitrification technique, according to the existing denitrification technology. The nitrogen emission concentration of the coal-fired units reach the current national emission standards after transformation.
