In normal environment, the flame color of gas stove is bright light blue. If the flame finds yellow and other colors, it should be noted that the gas stove may have the following obstacles.
The status of the throttle is not well regulated. When burning, the mixture of gas and atmosphere is symmetrical, and the flame will be blue. At this time, there is less smoke and more fire power. If the gas is not mixed with oxygen in the atmosphere, the combustion is not complete, and the heat flow is low, the flame will be yellow, and the smoke is relatively large. Lift up the gas stove to see that there is a "small Paddle" at the bottom, which is used to master the two air doors in the watch. Adjust the air vane, increase the air inlet area, and adjust to the blue flame.
The throttle passage is blocked. There are carbon deposits, rust, spider webs and other dirt in the ejector tube, which will also affect the ability of the ejector and cause yellow fire. At this time, the dirt in the ejector should be cleaned, and the yellow fire can be broken.
Nozzle bore is too large. There are some differences in the application of gas source according to the size of nozzle aperture. When the aperture is too large, the flow of gas will cross the rated flow, and yellow fire will be generated; when the oxygen is not in real time, black smoke will also be generated. In such an environment, only the nozzle suitable for the air source needs to be changed.
Accurate application of gas is related to life and safety. Generally, attention should be paid to: 1. The rubber tube under the gas stove should be changed once every two or three years to avoid the safety and disorder of gas leakage caused by aging and continuous carelessness of the rubber tube. 2. When using gas appliances, people shall not leave, in case that the pressure drops suddenly, it is found that the natural gas leaks due to the fire break. Once the flame is found to put out the fire by itself, the front valve and gas appliance valve shall be closed at the same time, and the windows shall be opened for ventilation. If it is not possible to start or close the range hood or other electrical appliances at the same time, it shall be burned again after the peculiar smell is dissipated. 3. Do not put inflammables near the stove. The bottom of the pot is connected to dry, saving (the air hole of the gas stove caused by the water point causes the stove to rust and block). 4. Clean well, including burner and gas stove surface. As soon as the micro switch is turned on, a continuous series of electric sparks can be generated, causing the fuel to complete combustion. See whether the pulse battery is melted by the high temperature, and whether there is a dirty cover that makes it unable to transmit electricity to the eye of fire. After cooking, clean the appearance of the gas stove in real time, and remove the oil splashed when cooking.
