Solutions for reducing nitrogen oxides in low-nitrogen gas boilers

Solutions for reducing nitrogen oxides in low-nitrogen gas boilers

The nitrogen content in natural gas is relatively low, so fuel-type NOx is not its main control type. Thermal NOx refers to the oxidation of N2 in the combustion air at high temperatures to produce NOx. The generation mechanism of thermal NOx is generally described by the Zeldovich mechanism: when the temperature is below 1500°C, the amount of thermal NOx generated is very low; above 1500°C, for every 100°C increase in temperature, the reaction rate increases by 6 to 7 times. In actual combustion processes, due to the uneven temperature distribution within the combustion chamber, if there are localized high-temperature areas, more NOx will be generated in these regions, which may affect the entire combustion chamber.

Driving environmental protection with low-nitrogen burners

Driving environmental protection with low-nitrogen burners

Environmental protection has become a topic that relates to various aspects of people's daily lives. The contradiction between environmental protection and economic development has become a concern for everyone. With the continuous development of the economy, these issues have become urgent. Previously, the country has been vigorously promoting low-carbon travel and low-carbon living to reduce carbon dioxide emissions. Today, I will talk about 'low nitrogen emissions' and 'low nitrogen living' in the industrial sector. Many people may be familiar with low carbon, but when it comes to low nitrogen, many may feel confused. What exactly is low carbon, and what is a low nitrogen burner?
