The starting speed of the integrated oil and gas burner may be affected to a certain extent in a low temperature environment. Low temperature will cause the fluidity of the fuel to decrease, especially the fuel oil part, which is prone to poor atomization due to increased viscosity. Insufficient atomization will slow down the mixing speed of the fuel and air, and it will take longer to form a combustible mixture during ignition, thus delaying the starting process. In addition, in a low temperature environment, the temperature of the metal parts inside the integrated oil and gas burner is low, and the heat dissipates faster. The spark generated by the ignition device takes longer to reach the ignition point of the fuel, further extending the starting time.
Combustion stability may also fluctuate in a low temperature environment. Low temperature will affect the density of the air, so that although the oxygen content of the air entering the integrated oil and gas burner has not changed, the oxygen molecules per unit volume are denser. If the air conditioning device of the integrated oil and gas burner does not adapt to this change in time, it may cause an imbalance in the oil and gas mixture ratio. Too much oxygen in the mixture will speed up the combustion speed and easily cause deflagration; insufficient oxygen will cause incomplete combustion, produce black smoke or unstable flames, all of which will destroy the stability of combustion.
The preheating system of the integrated oil and gas burner plays a key role in low-temperature starting and stable combustion. A high-quality integrated oil and gas burner will be equipped with an automatic preheating function to heat the fuel pipeline and atomization device before starting, reduce fuel viscosity, and improve the atomization effect. At the same time, the preheating system can increase the temperature of the internal components of the integrated oil and gas burner, reduce heat loss, and help the ignition device quickly reach the ignition condition. If the preheating system performance is insufficient, it is difficult to effectively improve the fluidity and atomization quality of the fuel at extremely low temperatures, and the starting speed and combustion stability will be significantly affected.
The adaptability of the fuel supply system directly affects the combustion state at low temperatures. Low temperatures may cause slight blockages in the fuel filter or pipeline, making the fuel supply unstable and causing intermittent combustion. For the gas part, low temperatures may cause gas pressure fluctuations. If the pressure regulating device of the integrated oil and gas burner does not respond in time, the gas supply will fluctuate, and the flame will jump or go out. Stable fuel supply is the basis for maintaining stable combustion. Insufficient adaptability of the supply system at low temperatures will directly affect the combustion effect.
The low-temperature adaptability of the ignition system is crucial to the starting speed. In a low-temperature environment, the ignition electrode may become less conductive due to frost or moisture, and the intensity of the spark generated will be weakened, making it difficult to ignite the mixture. Some integrated oil and gas burners will set up moisture-proof heating devices at the ignition system to prevent the electrode from frosting and ensure the spark intensity. Without this design, the ignition system is prone to failure in a low-temperature and high-humidity environment, which will not only make it difficult to start, but also cause the flame to go out during the combustion process due to unstable sparks.
The response speed of the control system of the integrated oil and gas burner at low temperatures affects the combustion stability. Advanced integrated integrated oil and gas burners are equipped with intelligent control systems that can monitor the ambient temperature and combustion status in real time, and automatically adjust the oil-gas mixture ratio, air supply and ignition frequency. In a low-temperature environment, the control system will increase the preheating time in advance, adjust the air door opening to adapt to changes in air density, and ensure that the mixture concentration is in the optimal range. If the control system responds laggingly or the adjustment accuracy is insufficient, it cannot respond to changes caused by low temperatures in time, and the combustion stability will be affected.
Long-term low-temperature operation may increase the wear of the integrated oil and gas burner components, indirectly affecting the starting and combustion performance. At low temperatures, the metal parts inside the integrated oil and gas burner are prone to thermal expansion and contraction stress due to frequent temperature changes. If the material or assembly process is not good, gaps or looseness may occur, resulting in gas leakage or abnormal air supply. In addition, in a low-temperature environment, the water vapor generated by combustion is easy to condense in the flue. If the exhaust system is not smooth, the condensed water may flow back into the integrated oil and gas burner, corroding the components and further reducing the starting speed and combustion stability.
