This kind of energy-saving stoves can be divided into three categories:

energy-saving stoves based on the principle of no-empty burning;

There is a lot of empty burning waste in the process of cooking. Generally, the waste rate of empty burning accounts for more than 31% of the whole cooking time. The energy-saving stove without empty burning solves the problem of empty burning waste and achieves the energy-saving effect of "starting from the fire, extinguishing the fire and avoiding empty burning". There are more than a dozen domestic manufacturers of this kind of stove, but most of them cannot be popularized in the market because of their stability and durability.

Energy-saving cookstoves with premixed burner:

Hotel cookstoves are generally red flames, because the burning rate is low, and a lot of fuel gas or oil is lost without being fully burned. With premixed burner, full combustion can be realized, and the fully burned flame is purple, and the temperature can reach 1211-1411 degrees, so the absorption rate is naturally improved. The energy-saving rate is higher if energy-gathering furnaces such as constant mining furnace, air heating furnace and infrared ceramic plate furnace are added to increase absorption. At present, there are not many hotels and catering enterprises that use energy-saving stoves in China, and the awareness of energy conservation needs to be further popularized.

Anti-burning

means reducing the burning time during non-cooking time, such as dividing vegetables, adding ingredients, washing pots and so on. Generally, liquid fuels such as diesel stoves and alcohol-based stoves are more difficult, while gas stoves will be better. The key is to keep the fire well.
