Tempering furnace is a key equipment in metal heat treatment process, the nitrogen oxides (NOx) in flue gas emissions pose a threat to the environment and human health. With the increasingly strict environmental regulations, tempering furnace denitrification technology has become the focus of industrial environmental protection.
While tempering furnaces improve metal properties, their combustion process may produce NOx, which is harmful to the environment and human health. Therefore, the development and application of effective denitrification technology is of great significance to realize the green transformation of industrial production. NOx emissions not only lead to the formation of acid rain and photochemical smog, but also may cause respiratory diseases and have long-term effects on human health. In addition, NOx emissions can also exacerbate climate change and increase the greenhouse effect.
Denitration technology includes pre-combustion control and post-combustion control. Among them, pre-combustion control reduces NOx generation by optimizing combustion conditions, while post-combustion control converts generated NOx into harmless substances by chemical methods. Pre-combustion control also includes low-nitrogen combustion technology and gas recirculation.
1, low nitrogen combustion technology: by adjusting the combustion parameters, such as air fuel ratio and combustion temperature, reduce NOx generation.
2, flue gas recirculation: part of the low-temperature flue gas is reintroduced into the combustion chamber to reduce the combustion temperature and inhibit NOx generation.
Our SCR denitrification technology is to use ammonia or urea as a reducing substance to reduce NOx to nitrogen and water under a certain temperature and catalysis. SCR denitration technology is suitable for large tempering furnaces in continuous operation and can achieve denitration efficiency of up to 98%.
Tempering furnace denitrification is an important link to achieve industrial green production, with the continuous progress and innovation of technology, denitrification technology will be more economical and efficient, and provide strong support for the sustainable development of industry.
