Friends who often cook at home know that when the gas stove is used normally, the flame of the gas stove is blue, but sometimes the flame turns yellow, or the newly bought gas stove, many of them are yellow Flame, what is the reason for this?
This is caused by insufficient gas combustion. This kind of incomplete combustion yellow flame is low in temperature, weak and weak, and usually has some pungent smell. Gas poisoning.
Usually this kind of yellow flame can be solved by adjusting the air regulating plate at the bottom of the gas stove to control the area of the air intake and increase the concentration of oxygen.
Some gas stoves that have been used for a long time may also be caused by the blockage of the gas stove. At this time, cleaning the impurities in the outlet of the gas stove can usually solve the problem.
According to national regulations, the service life of gas stoves is 8 years, and gas stoves beyond the service life are not safe. If possible, it is recommended to replace them with new ones in time.see more:Best Professional Gas Stoves for Homes
When choosing a new gas stove, you need to pay attention to the following aspects:
- Size
If you are replacing a new gas stove, since most households use embedded gas stoves, it is recommended to measure the size of the old gas stove and the size of the opening of the stove, so as to avoid the new gas stove being unusable due to the size of the opening.
- Energy efficiency and firepower
Energy efficiency grades are divided into 5 grades, among which grade 1 has the best energy-saving effect and grade 5 has the worst energy efficiency effect. Therefore, when purchasing a household gas stove, try to choose a gas stove with energy efficiency grade 1-2. This kind of gas stove has the best energy-saving effect.
In addition to energy efficiency ratings, firepower is also an extremely important point in gas stoves. Friends who like stir-frying and high firepower can choose a gas stove with a power of 5KW or more, and most household gas stoves with a power of 3.8KW can be used with confidence.
- Stove head and fire cover
The burner head and the fire cover are important parts of the gas stove. These two positions have been in contact with the flame for a long time. The material requirements are relatively high, and they need to be resistant to high temperature and corrosion.
The commonly used materials for the burner head and fire cover are copper, alloy, stainless steel, iron and other materials. Among them, the material of copper fire cover and copper burner head is the best, and the iron fire cover and burner head are the worst. The burner is very prone to rust, blocks the fire outlet, and has a relatively short service life.
If possible, be sure to choose a gas stove with a copper burner and a copper fire cover.
- Panel
Gas cooker panels are mainly made of stainless steel and tempered glass. Stainless steel panels are durable and resistant to high temperatures, but they are inconvenient to clean and easily accumulate oil stains.
Although tempered glass panels are not as good as stainless steel in terms of durability and heat resistance, they are extremely easy to clean, and the current tempered glass is sufficient for gas stove panels, so here we recommend gas stoves with tempered glass panels first.
- Air intake method
At the beginning, we said that insufficient combustion will lead to yellow flames, and the way of entering the wind is an important factor that determines the firepower and safety.
The air intake methods of gas stoves mainly include upper air intake, lower air intake and full air intake. Among them, the firepower of the upward wind is relatively weak, but it is safe after all; the gas stove with the downward wind has relatively large firepower, but its safety is relatively poor, and it is usually used in embedded gas stoves. If the air circulation below is poor, it is very easy for the flame to burn insufficiently.Also read:Best wall oven microwave combo
The way of full air intake combines the advantages of upper air intake and lower air intake, with high firepower and more complete combustion, so full air intake gas stoves are the first choice for gas stoves.
- Security
At present, the country has very strict regulations on the safety of gas stoves. For example, gas stoves must be equipped with a flameout protection device. Therefore, when choosing a gas stove, you must choose a gas stove with a 3C mark, try to choose some big brands, and avoid some fake and shoddy ones. product.
For example, some gas stoves have functions such as anti-dry burning and child lock, which are extremely safe, so you can pay more attention when purchasing.
In addition, when purchasing a gas stove, you also need to pay attention to the gas source used at home. Different gas sources have different combustion values and pressures. Therefore, gas stoves need to have corresponding nozzles. The nozzles of different gas sources are not universal, and mixed use can easily cause danger. Pay attention when purchasing.
