Burner determines the fuel combustion process can achieve complete combustion, so to reduce NOx generation to consider the performance of the burner. According to the control degree of NOx generation by the burner, the low-nitrogen burner is divided into the following 6 types:
1. Stage burner
The burner determines whether the combustion process can achieve complete combustion, so the performance of the burner should be taken into account to reduce the production of NOx. According to the degree of control of NOx production by burner, we divided the low nitrogen burner into 6 types:
2. Self-recirculation burner
One is to use the pressure head of combustion-supporting air to absorb part of the burning smoke back into the burner and burn it with the air. Due to the recirculation of flue gas, the heat capacity of flue gas is large, the combustion temperature is reduced, and NOx is decreased. Another kind of self-recirculation burner is to put part of the flue gas into the recirculation directly in the burner and add the combustion process. This kind of burner has the dual effect of inhibiting nitrogen oxide and saving energy.
3. Thick and light type burner
The idea is that some of the fuel is burned too much, and some of the fuel is burned too little, but the total amount of air over the air remains the same. Since both parts are burning away from the chemical equivalence ratio, the NOx is very low, which is also called deviation combustion or non-chemical equivalent combustion.
