boiler desulfurization denitration retroduction

CN1923341A - Device and method for coal-burning boiler

The invention relates to a device for removing several pollutants of boiler smoke. Wherein, it comprises (1), before or after the static deduster 5 of smoke channel 4, ejecting into ozone O3 at low temperature section as 110-150Deg. C, while the ratio between ejected amount and nitrogen oxide is 0.5-1.5, to oxidize the low-level nitrogen oxide insoluble into soluble high-level nitrogen oxide

PAPER OPEN ACCESS Progress of Desulfurization and

25/04/2020 · At present, desulfurization and denitration are mainly divided into desulfurization technology and denitration technology. Desulfurization technology [6, 7] is divided into three categories according to the desulfurization time: pre-combustion, combustion and post-combustion flue gas desulfurization. Flue gas desulfurization (FGD) is the most widely used and mature technology to
