Note one
Most of the infrared gas stoves currently on the market are improved on the basis of the original gas stove burner, and are not designed according to the requirements of infrared rays. For example, according to the design requirements of the infrared burner, the air required by the burner is all sucked by the ejector without the need for secondary air, which is not possible with the original gas stove. The infrared burner also needs the supply of secondary air, but the secondary air on the infrared cooker surface is difficult to be mixed with the gas to burn, which causes the incomplete combustion to increase, which deteriorates the sanitary conditions of the kitchen.
Infrared gas stoves are flameless combustion. Some infrared products use fully premixed combustion. The combustion should be carried out in the fire hole and on the surface. The flame on the surface of the fire hole is very short. Although it is a flameless combustion, it is not a true flameless combustion. (There is a short flame). The true flameless combustion is mainly to control the reaction on the surface of the catalyst in the fire hole. When burning, it can reach a completely flameless combustion state, realizing flameless combustion.
Different ways of energy release, many of the infrared rays on asbestos are first heated by a metal mesh or a porous ceramic plate, and then a second wavelength of infrared light is released at a high temperature by a heated metal mesh or a porous ceramic plate, which looks like a burning effect and a true infrared ray. The same, but the energy saving effect is very different. The true infrared rays should completely release energy by infrared radiation, which fundamentally avoids the loss of combustion energy caused by visible light.
Note two
The purchase of infrared gas stoves should be purchased from regular manufacturers and have perfect after-sales products. Take note of the purchase of a specialty store or a reputable mall. When purchasing, pay attention to the instructions of the gas stove to see the material and principle of the combustion of the infrared burner. Whether the product is in series or not, is there a burner suitable for all kinds of gas (gas, liquefied gas, natural gas, biogas, etc.).
Note three
When the family's existing gas stoves are modified with infrared burners, they must purchase the products of regular manufacturers. There is a certificate of conformity, and the appearance of the products is smooth. It is best to use a cast iron chassis. The cast iron chassis is not afraid of burning for a long time. The infrared burner must be installed by a professional to avoid inconspicuous energy-saving effects or safety problems caused by improper installation.
Note four
Infrared gas stoves have high heat, which is not suitable for Chinese people to make rice risotto requirements. Therefore, when choosing, you should choose an infrared stove with firepower adjustment function. If there is no firepower adjustment, the best one is the infrared burner, and the other is the ordinary atmospheric burner.
Note five
5, on-site experiment: buy infrared gas stove, it is best to test fire in the store, a look at whether the ignition is easy to use, the second is to see if the infrared burner can generate infrared rays within 30 seconds of ignition, compared with ordinary gas stoves, see if Can achieve the energy-saving effect of product promotion. Third, check whether there is a product certificate, instruction manual, warranty list, and product accessories list in the package. There should be a nameplate on the main body of the cooker, indicating the model, gas type, gas pressure rating, manufacturer name, etc.
