Causes and elimination methods of yellow fire in gas stove
But why this yellow gas stove fire points: one is the uniform mixing of gas and air (a less air, less space or mixed); two is the combustion exhaust gas is not good (two times less air, increase the two air mixing area, which is discussed above); three is the gas fire the excess hole nozzle (fire hole and flow of the right size).
The following several reasons and corresponding solutions to produce yellow fire:
1, insufficient supply of primary air, resulting in poor combustion. The user can adjust the air door plate and increase the air inlet area to solve the problem. The flame can be changed from yellow to blue.
2. The throttle passage is blocked. There are carbon deposition, rust, spider nets and other dirt in the ejector tube, which will also affect the ejection capacity and produce yellow fire. At this time, the carbon, rust or spider nets in the ejector can be removed, and the yellow fire can be eliminated.
3, nozzle aperture is too large. The nozzle aperture size is different according to the use of gas source. When the aperture is too large, the gas flow exceeds the rated flow, and the yellow fire occurs. When the oxygen is seriously insufficient, the smoke will also produce black smoke. In this case, it is only necessary to replace the nozzle which is suitable for the gas source.
4, nozzle and injector are not concentric. Adjust the installation position of ejector so that the center of them is on one axis.
5, burner with dirt, dust or water vapor, etc.. The dirt on the burner can dredge the fire hole with fine wire to keep the fire hole unobstructed. Or after the dust, water vapor disappears, the flame will return to normal.
6, liquefied gas to the bottom of the bottle will also appear yellow fire. This is due to the use of liquefied petroleum gas, the content of the components in the cylinder, such as (C5) increased, and not easy to gasification, combustion space and time is too large, must adjust the intake air door in time, in order to eliminate the Yellow fire.
7, gas quality instability will also form yellow fire.
