Experts teach you how to buy gas stoves.

Whether the gas stove is good or not depends on the burner. The burner is called the heart of the stove. As the core component of the cooker, the cost of burner accounts for 1/3 of the total cost. However, the different air intake modes of the cooker are related to the safety, power and energy saving performance of the cooker. The furnace head material is mainly made of stainless steel, cast iron and copper. Because the burner is easy to deform after a long period of fire barbecue, the material and thickness of the burner are very important. Generally speaking, the heavier the burner, the better. Experts concluded that copper burner should be the first choice for consumers, and its advantages are: 1, good thermal conductivity, good heat dissipation, high thermal efficiency and not easy to temper. However, aluminum alloy has poor thermal COnductivity, poor heat dissipation and decreased thermal efficiency, which is easy to cause tempering, and the co content is relatively high when burning. 2. Because of its inherent corrosion resistance, the copper burner does not need the protection of external oxide film, so it is durable. Aluminum alloy is usually coated with AL2O3 protective film to prevent corrosion. However, in the kitchen, you often come into contact with acid salts. The protective film on the surface is easy to be damaged by corrosion, and corrosion spots appear on the surface, which affects the appearance and reduces the service life. 3. The melting point of copper is as high as 1083 degrees, and it is not easy to melt and deform even under the condition of high firepower, thus effectively prolonging the service life. However, the melting point of aluminum alloy is low, and the smoke heat flux is low when it is less than 600 degrees. It is easy to turn black and melt under high temperature for a long time, which greatly shortens the service life of the cooker. Due to the integrated design of the burner, when the burner is melted and replaced, it needs to be replaced as a whole. This situation has been confirmed by consumers' long-term use, which is a major disadvantage of aluminum alloy burners. 4. In addition, the copper burner has good material, heavy weight, high grade and beautiful appearance.
