The Olympic flame with bright symbols, boldness, unity and friendship has become the symbol of Olympic action, which makes people of different colors go all the way for a unified indicator. One way, one kind of fire. The Olympic Games connect the chastity of the Olympic flame with the harsh ancient times. In the long process of torch transmission, it passes through different cities, mountains and oceans. It is probably found in any poisonous weather. Why can't the Olympic torch put out the fire?
Torches can be burned in various situations, which can not be separated from the burning supply system and the incinerator. In this case, the incineration supply system can be divided into three parts: fuel, pressure stabilizing assembly and regenerative assembly. During the continuous evolution and development of the Olympic torch, the fuel has gradually evolved from a very early magnesium block to propane and other gases that can be consolidated and burned in extreme weather. Propane gas has the characteristics of high burning heat, low boiling point, low temperature, bright flame, strong light and liquefaction pressure, so it can adapt to all kinds of poisonous weather. The stable pressure assembly and regenerative assembly further guarantee the solid burning of fuel. Pressure stabilizing assembly can consolidate the pressure required for gas incineration and connect the gas strength under different weather conditions. The return assembly may be able to connect the fuel chamber temperature, thus ensuring the fuel combustion pressure. The fuel alone is not enough. If there is a shortage of incineration technology, it is difficult to guarantee the solidity of the flame. Therefore, scientists from all over the world have paid great attention to the plan of the incinerator. With the development of the times, the incineration technology of the Olympic torch incinerator is also in continuous development.
It is said that the very early Olympic flame behavior originated from the 11th Olympic Games held in Berlin, Germany, in 1936. In this summer Olympic Games, except for two sessions without torches, there are other torches. In addition, there are about 19 torches in 2016. In the process of development, the shape of the torch has evolved continuously. For example, the shape of the olive leaf was used for reference in the Athens Olympic torch, and the paper scroll was used for reference in the Beijing Olympic Games. The torch of London Olympic Games is integrated into 8000 rings to salute 8000 fire handles. In addition to its shape, the Olympic torch is continuously integrated with the very new science and technology of other countries to ensure its long burning.
However, in the era of torch relay, there will be many unexpected situations. So once the fire is put out, it is necessary to use the kindling left in the kindling lamp to ignite the kindling. There is a partition in the torch combustion chamber, which is divided into the main combustion chamber and the pre combustion chamber. Two combustion chambers are connected, one is put out of the fire, and the other is burnt by the kindling lamp.
The kindling lamp is specially used to store kindling. It's said that after the end of each day's behavior, kindling will be kept in the kindling lamp until the next day, when the torch relay starts again, it will be used to burn the first torch again.
Underwater legend of the Olympic flame
In 2000, Sydney Olympic torch held a "romantic trip". The torch was equipped with diving gear, and the special torch was held in the waters of the Great Barrier Reef for 3 minutes. This is the first underwater torch in the history of the Olympic Games. In fact, the underwater flame is the particle in the initiating state, and the detailed existence mode can be understood as a stream of connected luminous gas.
According to satellite, the Olympic flame
According to legend, the 1976 Montreal Olympic flame adopted the practice of "Star Tour". On July 13, it was burned in Olympia. After the fire spread to Athens, it was not transmitted by steamboat, plane or relay, but by satellite laser technology to Canada. Through sensors, the heat energy of the flame was converted into electric waves and transmitted to Canada by satellite, and then the torch was burned in Montreal by laser.
