I saw a friend inquiring about whether the tempering of the step heating furnace is related to negative pressure. Today, Yinuo will come to answer with you. First, let's understand what tempering is.
Backfire is when the mixed gas of air and gas flows out of the burner nozzle at a speed lower than the flame propagation speed, the flame returns to the burner to burn. The positive pressure in the furnace is generally tempered. The reasons for tempering are generally as follows:
1. The furnace is operated under positive pressure; 2. The gas pressure is low; 3. The gas pipeline is not equipped with a flame arrestor; 4. The air door is adjusted too much.
The methods to prevent backfire include the positive pressure operation of the step-by-step heating furnace, pay attention to the operation of gas pressure, install a flame arrestor on the gas pipeline, and adjust the scale of the air door reasonably.
