With the shortage of petroleum and natural gas energy, the price of gas is saved and increased, and the gas stove saves energy and becomes a first-choice substitute stove for enterprises and public institutions, hotels, restaurants, troops and schools in cities. A small city generally has at least 100000-200000 unit stoves, which are replaced at the speed of 20% per year, and 20000-40000 unit stoves per year need to be provided with gas stove energy-saving products, which does not include surrounding county cities and towns. Therefore, the energy saving of the gas stove is a necessary way for sustainable development.
The infrared ray has longer wavelength than visible light, has heat effect and extremely strong penetrating power, and is not easy to be absorbed by atmosphere, so the infrared gas stove has obvious energy-saving effect. The infrared ray carries energy, and the infrared ray stove is manufactured by utilizing the characteristics of the infrared ray, so that the energy-saving efficiency can reach more than 35 percent. The infrared radiation plate made of special refractory material converts flame into infrared ray when the flame is burnt, so that the heating process of an object is accelerated; the performance of the gas stove is greatly improved due to the transmission of infrared radiation; compared with the common gas stove, the infrared energy-gathering stove can reach 1180 ℃ high temperature (600 and 700 temperatures of the common stove), so that the cooking time is reduced; the infrared energy-gathering stove can be completely burnt without blackening the bottom of the pan, and is cleaner and more sanitary; the nitrogen oxide gas (a carcinogenic gas) of the infrared energy-gathering stove is discharged to 1/20 of that of a common stove, so that the infrared energy-gathering stove is more beneficial to human health; the thermal efficiency of the infrared energy-gathering stove is 68 percent, the energy is saved by 37 percent, and the thermal efficiency of the common stove is only about 53 percent.
