Two 5-ton Low Nitrogen Gas Burners Will Be Shipped.

Flue gas recirculation technology: Part of the flue gas is sucked into the air supply system of the burner for recirculation. By reducing the proportion of oxygen in the combustion air, increasing the total amount of air and flue gas, the heat capacity is increased and the combustion temperature is lowered.
Graded combustion technology: By optimizing the internal structure of the burner, air and gas can achieve staged combustion in the combustion chamber. By organizing the flow field of air and gas through the combustion head, the combustion chamber is divided into a main combustion zone (lean fuel) and a re combustion reduction zone (rich fuel). In the main combustion zone, the excess air coefficient is much greater than 1, effectively suppressing flame temperature; In the combustion reduction zone, the already generated NOx undergoes a reduction reaction when encountering hydrocarbons and incomplete combustion products, reducing NOx to nitrogen molecules and suppressing the generation of new NOx.
Flue gas recirculation technology: By controlling the airflow velocity at the outlet of the combustion head, local flue gas recirculation is formed at the outlet of the flame tube, reducing the concentration of fuel and oxygen while absorbing flame heat.
