The technical characteristics of activated coke dry desulfurization and denitrification are as follows: (1) In view of the complex flue gas working conditions with sulfur, nitrogen, oxygen, high water content and large fluctuations produced by sintering, as well as working conditions with high requirements for removal efficiency and index stability, advanced two-stage activated coke drying Method purification technology; (2) In order to meet the ultra-low emission requirements of particulate matter, proprietary porous plate and microporous plate technology are adopted; (3) Activated coke feeding and unloading adopts advanced rotary sealing valve technology to reduce the powdering rate of activated coke and improve the sealing effect.

Oxygen (O) is a harmful element in steel such as 09cupcrni-a steel equivalent. Although manganese, silicon, iron and aluminum are added to deoxidize the steel at the end of steelmaking, they can not be removed completely. During the solidification of molten steel, the reaction of oxygen and carbon in the solution will produce carbon monoxide, which can cause bubbles. Oxygen mainly exists in the form of FeO, MnO, SiO2, Al2O3 and other inclusions in the steel, which reduces the strength and plasticity of the steel. Especially, it has serious influence on fatigue strength and impact toughness.

Q355NH material has a protective rust layer that resists atmospheric corrosion and can be used to manufacture low-alloy structural steels for steel structures such as vehicles, bridges, towers, containers, etc. It can also be used to manufacture structural parts such as containers, railway vehicles, oil derricks, seaport buildings, oil production platforms, and containers containing hydrogen sulfide corrosive media in chemical and petroleum equipment.
