【 摘 要 】

With the rapid development of the economy, nitrogen oxide pollution has become a problem that cannot be ignored. Therefore, it is necessary to strengthen the control of nitrogen oxides in coal-fired power plants. This paper introduces the current denitration technology overview, including the selective catalytic reduction (SCR), non-selective catalytic reduction (SCNR), SCR-SNCR mixed denitration technology, including acid absorption, Wet denitration technology such as lye absorption method, oxidation absorption method and activated carbon absorption method, as well as coal-fired flue gas combined desulfurization and denitration technology were introduced. The process principle and characteristics were briefly described, and the development direction of flue gas denitration technology was introduced. The outlook was made.Introduction Nitrogen oxides (NOx) is an atmospheric pollutant that combines with water in the air to promote the formation of acid rain. It also produces photochemical smog under certain conditions with other pollutants. It also participates in the destruction of the ozone layer and oxidation. Nitrogen will destroy the ozone layer in the high-temperature stratosphere and increase the incidence of skin cancer. Therefore, while building a power plant to meet social energy needs, it should strengthen the effective control of nitrogen oxide emissions from coal-fired power plants, reduce air pollution, and reduce the serious damage caused by nitrogen oxides emissions to human living environment. The emission of nitrogen oxides from power plants. Denitration technology is particularly important.
