Is the energy-saving cover of gas stove useful?

There is a certain energy-saving effect, but it is not big. At present, China's technology in this field is not mature, and there are great security risks.

The gas hood sold in the market plays the role of gathering flame, but this situation is only for small fires. If fire is used, the cover can not only play the role of saving solar terms, but also increase the use of gas. It is more likely that gas leakage will occur because the gas stove can't burn completely, or it will damage the gas stove. It is recommended to use this kind of thing less.

Extended data:

Generally, the combustion of a table cooker can smoothly supply oxygen above the stove surface; For embedded cookers, according to the requirements of the Code for Design of Town Gas and other standards, if there is a cabinet below, the cabinet must be set aside 80? More than one square centimeter of holes are connected with the atmosphere, which is precisely to ensure that the combustion chamber can continuously supply oxygen and waste gas.

Once this kind of "energy-saving hood" is used, the almost airtight hoop obviously hinders the circulation of air, so that the burnt waste gas cannot be discharged in time, and the required oxygen (contained in the air) cannot be supplied smoothly, resulting in "incomplete combustion".
