Low-nitrogen burner technology is a new combustible technology developed in the past two decades to meet the needs of environmental protection. The following is some relevant knowledge of nitrogen oxides.

Nitrogen oxides NOx Nitrous oxide N2O, Nitric oxide NO, Nitrogen dioxide NO2, Nitrogen trioxide N2O3, Nitrogen tetroxide N2O4 and Nitrogen pentoxide N2O5 and many other nitrogen oxides, of which NO and NO2 The pollution hazard to the atmosphere ranks first, and the NOx values ​​involved in the general environmental standards and emission standards are based on NO and NO2.

The harm of NOx to the human body and the environment is mainly manifested in the following aspects: ①NO has a strong affinity for hemoglobin in human blood (100 times greater than CO). Inhalation of NO by humans and animals will cause severe blood hypoxia, damage the central nervous system, and even Cause paralysis; ②NO2 has a strong stimulating effect on the respiratory organs, and can cause chemical lesions in the alveolar tissue.

Nitrogen oxides under the action of sunlight, due to the catalysis of ultraviolet rays, form a strong prickly and corrosive photochemical smog. It can stimulate the eyes and respiratory tract of people. In severe cases, it can cause vision loss, twitching of hands and feet, and long-term existence It can also cause arteriosclerosis and decline in physiological functions. In addition, this photochemical smog can also cause poor plant growth and severe corrosion of metal objects. Industrially developed countries in the world, such as the United States, Japan, and the United Kingdom, had air pollution incidents caused by NO. in the 1950s and early 1960s. The 1954 Los Angeles photochemical smog incident that shook the world was one of them.

As a member of the low-nitrogen burner manufacturer, we learned from the technical department that the low-nitrogen burner technology currently used can be divided into the following four aspects: ①Improve operating conditions; ②Improve combustion methods and devices; ③Improve Combustion chamber structure and combustion method; ④Use fuel with low nitrogen content.
