Introduction to Off furnace flue gas denitrification system, introduction to SCR denitration system advantages and characteristics

Off furnace flue gas denitrification systemis an efficient, stable and environment-friendly flue gas denitrification technology.，the product looks beautiful.，features include Environment friendly, Less secondary pollution, Environmental protection and pollution-free, Strong adaptability and Good selectivity，the principle is simple.Ammonia gas or other suitable reducing agent (such as urea aqueous solution) is sprayed into the flue gas upstream of the catalyst at high temperature. Under the action of catalyst, the reducing agent selectively reacts with nitrogen oxides (NOx) in flue gas to generate pollution-free nitrogen and water vapor. Because NH3 is selective, it only reacts with NOx and basically does not react with O2, so this technology is called selective catalytic reduction denitrification.，generally, it is composed of control system, Flue gas mixing and distribution system, Catalyst supply system, Catalyst reactor, Temperature control and monitoring system and other major components，This Off furnace flue gas denitrification systemThe structural design is more advanced and reasonable.。The following is to introduce the Off furnace flue gas denitrification system:

1、Brief introduction of Off furnace flue gas denitrification system

Off furnace flue gas denitrification systemit refers to the process of removing nitrogen oxides from flue gas to reduce environmental pollution. NOx is a pollutant harmful to the atmospheric environment, which has strong irritation and toxicity, and will lead to environmental problems such as acid rain and photochemical smog, and also endanger human health. The main principle of flue gas denitrification technology is to reduce NOx to nitrogen and water by adding appropriate reducing agent or catalyst in the combustion process or flue gas treatment system, so as to reduce NOx emission.，is a popular Off furnace flue gas denitrification system，multifunctional, with functions such as Improve energy efficiency, Improve working conditions, Promote sustainable development, Improve energy efficiency and environmental protection，has been favored by more and more customers.。
