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

01/03/2019 · This work summarizes the desulfurization and denitration technology of coal-fired power plants in China. Firstly, it summarizes the existing desulfurization and denitration technologies, then summarizes the research progress of the combined desulfurization and denitration technology in coal-fired flue gas, and forecasts the development of future desulfurization and denitration technologies.
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
25/04/2021 · Start-up operation of high temperature resistant desulfurization and denitration circulating pump: 1. Fill the pump with liquid. 2. Open the inlet valve in time (if the inlet valve is a one-way check valve, manual operation is not required). Pay attention to open the inlet valve to the maximum position. 3. Turn on the power supply. 4. Open the outlet valve.
Combined desulfurization, denitration and removing mercury (C-de-SO 2 /NOx/Hg) from flue gas is considered as the development direction of flue gas purification. The development and application of the desulfurization, denitration, removing mercury technologies are reviewed in this paper, and the advantages and disadvantages of
24/04/2021 · The special pump for boiler dust removal, desulfurization and denitration is divided into three types: wet, semi-dry, and dry according to whether water is added to the desulfurization and denitration process and the dry and wet form of the desulfurization products Large-scale desulfurization proces
What are the main methods of desulfurization and Apr 24 2021 · At present there are dozens of technical process types for flue gas desulfurization and denitrification. The special pump for boiler dust removal desulfurization and denitration is divided into three types: wet semi-dry and dry according to whether water is added to the and denitration process and the dry and wet form of the
The significance of desulphurization and denitrification is more obvious in removal SO 2 and NO x from flue gas emission during coal combustion. This paper summarized the latest progress of desulphurization and denitrification on wet, semi-dry, dry and microbiological purification, simultaneously. It is pointed out that the development and application prospects of simultaneous desulphurization and
