AI Technical Summary
The narrow air passage of the upper air intake burner leads to poor air distribution uniformity, which can easily result in localized excessively low or high air pressure, posing safety hazards and causing poor combustion performance.
Design a burner including a first air passage and a second air passage, wherein the horizontal area of the first air passage is larger than that of the second air passage. Air supplied by a blower first enters the first air passage and is evenly distributed, and then enters the second air passage to mix with the combustion gas, ensuring that the air flow rate is moderate and avoiding excessive or insufficient local pressure.
It achieves uniform air distribution and good mixing performance, improves the safety and combustion efficiency of the burner, and avoids the problem of unstable local gas pressure.
