The integrated gas burner's windproof and flame-stabilizing design utilizes a wraparound windshield to create a relatively enclosed combustion space, minimizing interference from external airflow. An integrated gas burner's flame is typically surrounded by a circular or grid-like windshield, effectively shielding it from direct impact from natural wind and range hood drafts. The windshield's height and density are optimized to ensure the flow of air necessary for combustion while simultaneously reducing airflow intensity, maintaining a relatively stable airflow environment for the flame and preventing excessive wind from causing it to tilt, flutter, or even extinguish.
The unique structural design of the flame stabilizer enhances the flame's resistance to interference, preventing it from being blown away from the combustion point by airflow. The integrated gas burner's gas outlet features a dedicated flame-stabilizing disc or holes. These components alter the mixing pattern of gas and air, creating a stable, high-temperature zone at the flame's base. This high-temperature zone ensures a continuous flow of gas, preventing the flame's base from being blown out even by minor air disturbances, thus ensuring the continuity and stability of the flame. The flame-stabilizing structure also ensures thorough mixing of gas and air before combustion, ensuring more complete combustion and a more concentrated flame, further enhancing wind resistance.
Precise gas-air ratio regulation is the core guarantee for windproof and flame stability, preventing flame instability caused by an imbalanced mixture. The integrated gas burner's built-in gas valve and air regulator automatically adjust the air intake based on the gas flow rate, ensuring an optimal mixture ratio. When external airflow changes threaten to affect the air supply, the regulator quickly responds by adjusting the cross-sectional area of the air intake duct or the gas injection velocity to maintain a stable gas mixture concentration. This dynamic balancing mechanism ensures that the flame receives sufficient oxygen under varying airflow conditions, preventing flame weakness, flashback, or flameout caused by oxygen depletion.
The integrated gas burner's optimized airway design minimizes the impact of airflow disturbances on gas injection, ensuring stable gas output. The gas passage from the gas valve to the integrated gas burner head features a streamlined design with a smooth, unobstructed interior, minimizing turbulence and pressure loss during gas flow. Furthermore, the gas nozzle at the end of the gas duct utilizes a special flow-guiding structure to ensure a uniform gas flow with a stable velocity and direction. This stable gas supply ensures smooth flame combustion, eliminating the fluctuations in flame intensity caused by gas pressure fluctuations or airflow disturbances, thereby reducing the source of flame instability.
The use of high-temperature-resistant materials ensures structural stability of the flame stabilization components in high-temperature environments, ensuring flame stability over long-term operation. If the windbreak and flame stabilization structure are subjected to long-term high-temperature combustion environments, insufficient heat resistance can lead to deformation and aging, compromising flame stabilization performance. Components such as the windbreak and flame stabilization plate of the integrated gas burner are primarily constructed of high-temperature-resistant alloys or ceramics. These materials maintain their original shape and strength under high temperatures and resist dimensional changes due to thermal expansion and contraction. This ensures the long-term effectiveness of the windbreak and flame stabilization design and prevents degradation of flame stability due to component deformation.
The heat recirculation design recovers flame heat, raising the ambient temperature in the combustion area and enhancing the flame's resistance to interference. Some integrated gas burners incorporate windbreaks and heat-reflecting materials to reflect some of the flame's heat back into the combustion area, raising the ambient temperature around the flame. This higher ambient temperature not only promotes full combustion but also prevents the flame from extinguishing due to sudden temperature drops when impacted by airflow. This heat circulation mechanism makes the combustion system more energy-efficient and enhances the flame's adaptability to complex airflow environments, further reducing the risk of flameout.
The integrated gas burner's interlocking backfire prevention mechanism responds quickly to flame anomalies, preventing the safety hazards associated with backfire. In extreme situations, such as a sudden drop in gas pressure or a sudden decrease in air supply, which could cause backfire, the integrated gas burner's built-in backfire prevention valve immediately closes the gas flow path, cutting off the gas supply. Simultaneously, cooling channels within the flame stabilization mechanism rapidly reduce the temperature along the backfire path, preventing the flame from propagating back into the gas pipeline. This dual protection mechanism intervenes promptly at the first sign of flame instability, preventing potential safety issues caused by backfire and allowing normal combustion to resume through re-ignition after the fault is resolved, ensuring safe and convenient operation.
