Using efficient and energy-saving gas equipment is an important measure to save gas. When natural gas burns, the flame is red and yellow, indicating lack of oxygen, and the phenomenon of "flameout" indicates too much air. At this time, the air door of the cooker can be properly adjusted. When the flame is purple-blue, it means full combustion. When cooking, prepare the food to be cooked before lighting it to avoid burning it into an "empty stove". To cook soup or stew, cook it with high fire first. Turn down the fire and keep the pot boiling without overflowing, but be sure to turn off the fire when you leave people. When cooking, the size of the fire can be determined according to the size of the pot, and the flame distribution area is the same as the bottom of the pot. It is best not to steam when cooking. Steamed rice takes three times as long as braised rice. When cooking pots and kettles, you should dry the water stains on the surface first, and then put them on the stove, so that the heat energy can be introduced into the pot as soon as possible and the gas can be saved. If the wind blows the flame vacillating, a thin sheet of iron can be used as a "windshield", which can not only ensure the concentration of firepower, but also save gas. We should choose high-quality gas appliance and keep it in good condition, so as to give full play to the best cooking efficiency, and timely eliminate the old gas appliance with poor combustion conditions. Rotary furnace uses 3 ~ 5% less gas than direct furnace, and desktop furnace uses 5% less gas than embedded furnace. The position of the cooker should be far away from the through flow, otherwise the windshield should be added to avoid reducing the thermal efficiency. When cooking with a double-barrel stove, use strong fire, and use slow fire when heating food such as casserole. As far as possible, use the lid to keep warm, which is more energy-saving. Adjust the heat to match the size of the bottom of the pot, and the heat should not exceed the edge of the pot; The larger the bottom area of the pot, the more gas-saving it is; After the food is boiled, use a small fire. Steaming and frying are both energy-saving cooking methods. Shower is more economical and energy-saving than bathtub bathing; When heating the same amount of bath water, the water heater can save about 30% gas compared with boiling water for bathing. The water heater should be installed as close as possible to the faucet, and the hot water pipe should be insulated to reduce heat loss; The outlet water temperature should not be too high. The higher the temperature, the more gas will be used. Gas appliance should be inspected regularly for maintenance, and the heat exchanger should be cleaned regularly to ensure the good performance and safety of gas appliance. ① Natural gas is fully burned. To make natural gas burn completely, it is necessary to add about 10 times of air. The method to determine the air volume is based on clear flame, stable combustion and pure blue flame. Therefore, the method is to adjust the knob air adjusting plate of the air connector to adjust the air volume to the best position. (2) The distance between the bottom of the pot and the burner should be appropriate, because the distance between the burner and the bottom of the pot is too large, and too much heat is lost, so it cannot be fully utilized. If the distance is too small, natural gas cannot be fully utilized. The distance is too small, and natural gas cannot be fully burned, which is a waste. According to the calculation, the best distance between the bottom of the pot and the burner is generally 20 ~ 30mm(3) Natural gas cookers should be placed in sheltered places, and the wind should not be blown directly to the cookers, because the wind blowing flames will take away a lot of heat, increase cooking time and cause natural gas waste. (4) Pay attention to keep the bottom of the pot clean, especially if the iron pot is used for a long time, a layer of black dirt will accumulate at the bottom of the pot. This kind of thing is unsightly, it will play the role of heat insulation and fire prevention, and it should be scraped off frequently. (5) aluminum pot, aluminum pot for boiling water, will accumulate a layer of hard scale over time, which will not only affect health, but also play the role of heat insulation and fire prevention, so it should be removed frequently.
