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.
Ultra-Speed Smoke Cooling tube is a completely new technology applied in Fangkuai boiler to achieve heat exchange. Mass transfer and heat transfer coexist. The unique arranged panel design increases the heat transfer area by 5 times and allows rapid heat exchange.
Advanced high-tech condenser fully absorbs the latent heat of vaporization generated by combustion, ensuring efficient use of energy and saving fuel with high efficiency.
Fangkuai PLC automatic intelligent control system is researched and developed independently, which is perfectly suitable for our boilers. It makes our boilers equipped with powerful and intelligent brains. Through operating on the PLC screen, users can control every boiler operation process easily and intuitively.
