Denitration | Nitrogen oxide control in hot-rolled alloy strip production: the importance of denitration technology

With the increasing awareness of environmental protection worldwide, governments have set strict emission standards for nitrogen oxides (NOx) emitted by industry. The steel industry, as one of the main sources of NOx emissions, needs to adopt denitrification technology to meet these regulatory requirements.

Hot-rolled alloy strip process plays an important role in many fields, whether it is the automotive industry, construction industry, energy industry, machinery manufacturing, shipbuilding industry, home appliance manufacturing, container manufacturing, welded pipe production, cold-formed steel production, etc. Hot-tied alloy strip process has high strength, good plasticity and weldability, and has become an indispensable material in these industries. With the progress of technology and the expansion of the market, the application field of hot rolled strip steel will continue to expand.

The heating furnace is mainly used in the production process of hot rolled strip steel. In the production process of hot rolled strip steel, the high temperature generated by the combustion process is the key factor to form NOx. By optimizing combustion parameters, such as air-fuel ratio and combustion temperature, thermal NOx generation can be reduced. Before the flue gas is discharged into the atmosphere, NOx emissions are reduced using denitrification equipment such as selective catalytic reduction SCR. SCR denitrification technology is an efficient method to convert NOx into nitrogen and water through catalysts and reducing agents such as ammonia or urea.
