In response to the national requirements for NOx emissions, China’s coal-fired power plants have basically completed denitrification transformation.
At present, coal-fired power plants usually choose three combination technologies for denitrification: low nitrogen combustion+selective catalytic reduction (SCR), low nitrogen combustion+selective non catalytic reduction (SNCR), and low nitrogen combustion+SCR+SNCR.
After combustion, denitrification is mainly achieved by reducing NOx in the flue gas to N2 to achieve emission control.
SCR denitrification occupies an absolute proportion in the denitrification market of thermal power plants, with the largest market share and a much higher market share than other denitrification technologies.
