NOx treatment | roaster why do you need tail gas denitrification?

With the development of industrial production, people’s awareness of environmental protection, baking furnace as an important equipment in the industrial production process, its exhaust gas treatment problems are increasingly paid attention to, nitrogen oxides (NOx) in the exhaust gas is one of the important factors causing air pollution, which will pose a serious threat to human health and ecological environment.

Roaster is widely used in metallurgical industry, metal smelting, chemical industry, building materials and other industries, its industrial process will produce a lot of nitrogen oxides, nitrogen oxides not only cause pollution to the environment, but also may produce particles, acid rain, photochemical smoke pollution through chemical reaction. This pollution poses a threat to our human health and ecosystems. Therefore, denitrification of the roaster exhaust gas is an important measure to achieve sustainable development and protect the environment.

At present, the technology of tail gas denitrification can be divided into dry and wet denitrification. Among them, dry denitration technology mainly includes selective catalytic reduction (SCR) and selective non-catalytic reduction (SNCR). In practical applications, selective catalyst reduction (SCR) technology reduces NOx to nitrogen (N₂) and water (H₂O) under the action of catalysts, thereby reducing the impact on the environment.

However, while the roaster tail gas denitrification technology has made some progress, it still faces many challenges in practical applications, such as the use of catalysts, energy consumption of the system, etc. For the roaster tail gas denitrification, we use coated honeycomb catalyst, which has better heat resistance and can improve the denitrification efficiency.

Roaster exhaust gas denitrification is the key to achieve the coordinated development of industrial production and environmental protection, through the use of our advanced denitrification technology, not only can reduce nitrogen oxide emissions, but also protect the atmospheric environment, but also enhance the green image of the enterprise, promote sustainable development.
