The fuel saving lamp invented in the Song Dynasty in China, why can the lamp be filled with cold wat

Thrift is the Chinese nation.

The traditional virtues are, firstly, that the ancient material abundance was not abundant, and secondly, our ancestors have always discouraged the waste of a life of luxury. Therefore, the things in life can be saved.

This virtue is also reflected in the design of ancient lamps. According to the fuel, there are two types of lamps in ancient China: anointed lamps and candle lamps, and anointed lamps are oil lamps with fuel oil. The fuel for oil lamps can be either animal fat or vegetable oil.

Qi Min wants to be skilled? The chapter on planting hemp says that hemp seed oil can be used as a candle, that is, it can be used to light lamps. The "Ego Chapter" also records:

Easa (i.e., white soybean) is oily green and lovely ......Can be candles. For oil lamps, energy saving first means saving fuel, so the ancient energy-saving lamps are fuel-saving lamps.

Energy-saving lamps were popular in the Song Dynasty. Lu.

In "Lu Fang Weng Ji? In the Chronicle of Zhaiju, it is said that the book lamp should not use copper, but the porcelain lamp is the most fuel-efficient. Shu has a porcelain cup, poured water into the lip hole, can save half of the oil, and in the "old school nunnery notes".

Energy-saving lamps are explained in more detail in Volume 10: Song Wen'an.

Gong (Song Bai) concentrated on the oil-saving lamp poems, now Hanjia (Lushan, Sichuan.

Yes, cover the lamp also. Make a tip at one end, pour cold water into it, and change it every night. Ordinary lamps are burned and dried by fire, so they dry quickly, which is not the case, and its fuel saving is almost half.

When Shao Gongji was pasting Han Jia, he was a doctor of the courtiers. According to Wen'an, it is also a Yujin order, and Hanjia has been producing this thing for several or three hundred years. 」

In the past, everyone thought that real lamps and lanterns did not appear until the Warring States period, but in fact, not later than the Shang Dynasty, China already had oil-fired lamps, and the materials and styles of oil lamps were gradually enriched and diverse. During the Warring States period, oil lamps were mainly made of bronze. By the time of the Han Dynasty, ceramic oil lamps became the mainstream.

During the Wei, Jin, Southern and Northern Dynasties, with the development of celadon technology, porcelain lamps began to be widely used. As Lu You said, the porcelain clamp lamp that conducts heat more slowly than copper is the most fuel-efficient - the lamp wall is designed with a mezzanine, and there is a round hole on one side of the lamp, and clean water is injected into the lower part of the interlayer from the round hole to cool down. The oil lamp reduces the temperature of the oil in combustion through cold water, reduces the volatilization of the oil, and thus achieves the purpose of energy saving.

Sichuan Qiongyao, Three Gorges Reservoir Area.

This energy-saving lamp has been unearthed in Fuling Shituo Tomb, Yueyang, Hunan and Tianjin, Chongqing Museum.

There are also such lamps, which shows that the area of circulation at that time was quite wide.

The principle of the fuel-saving lamp is to add water to the interlayer, control the oil temperature, reduce the oil volatilization rate, save fuel by 25%-30%, and play a role in environmental protection and energy saving. In other words, water evaporation is used to absorb heat!

Lamps are ancient lighting appliances. Porcelain lanterns began in the Eastern Han Dynasty and became popular after the Three Kingdoms. The lantern of the Six Dynasties is usually composed of three parts: the oil bowl, the supporting pillar, and the bearing plate.

The Yuemi celadon products of the Western Jin Dynasty of the Three Kingdoms, some of the supporting pillars are made into the shape of a man and a bear, a sheep, a cow and other animal shapes, and three Zeng shapes or hoove-shaped feet are placed under the bent age plate. The lamps of the Southern Dynasty were mostly inadequate, and the bollards became very high. The common shape of the Tang Dynasty was a bowl auspicious key saucer, with a ring on the inner wall.

According to Lu You's "Ju Chronicle", there is a kind of porcelain fuel-saving lamp in Shu, which is filled with cold water in the interlayer to cool down, which can save half of the oil.

The Tang Dynasty porcelain kilns in Sichuan are the most representative of Dengxia kilns. The production of oil lamps is also very chic, and the lamps are sandwiched and hollow. Water can be injected to reduce the heat of the lamp and reduce the overheating volatilization of oil, so as to achieve the purpose of fuel saving.
