development capabilities are leading the industry.
When combustion temperature exceeds 1300℃ during fuel burning, it comes into nitrogen oxide (NOx), which is a great hazard to the environment.According to NOx generation principle, main NOx generation factors include flame temperature, section oxygen concentration of burner, residence time of combustion product in high temperature zone, etc. Therefore, reducing NOx emission can achieved by optimizing combustion conditions.
Full-premixed combustion is a new environmentally friendly combustion type. It premixes fuel and air through precision adjustment and control, to ensure the gas and air are completely mixed, which can make the fuel burned completely and totally used.Surface combustion technology makes combustion more efficient, reducing NOx generation form the source and lower than 30mg/Nm³.
FGR combustion includes external flue gas circulation and built-in flue gas circulation. 10~30% of the flue gas from the tail of the boiler is sucked into the air inlet of the burner through the stainless steel flue gas duct, and mixed into the combustion air to enter the furnace chamber, thereby reducing the temperature of the combustion zone while also reducing the concentration of oxygen in the combustion zone, finally reducing the amount of thermal NOx generation and ensuring boiler NOx emission lower than 30mg/Nm³.
