What does the torch symbolize?

The torch symbolizes light and enlightenment.

Torch, also known as torch, is a tool to ignite and transmit kindling. Generally, it is made of flammable materials (such as rags soaked in oil or asphalt) tied to one end of a wooden stick. When it is used in the building, it can be inserted into the shelf on the wall, and it can also be used by hands outside.

As a sacred symbol, the history of fire can be traced back to prehistoric times. In Greek history, fire represents creation, rebirth and light. In Greek mythology, fire is a sacred symbol of hephaestus and a gift that Prometheus stole from Zeus.

Light of science and technology

During the Olympic torch relay, it is possible to face all kinds of unexpected climatic conditions, and strong winds and heavy rains will severely test the torch burning technology. In order to provide a reliable combustion system for the torch, the Aerospace Science and Industry Group carried forward the aerospace spirit of "being able to endure hardship, fight, tackle key problems and contribute" and contributed a reliable "core" to the Olympic flame. The combustion system of this heart includes three parts: burner, voltage stabilizer and gas storage tank.

The burner adopts an innovative double flame scheme, that is, the pre-combustion chamber plus the main combustion. This is the first time that the precombustion chamber is separated from the main combustion chamber in the design of the Olympic torch. This design will ensure that the torch will not be affected by strong wind with the flame in the pre-combustion chamber, and the flame derived from the main combustion chamber will make the whole torch burn vigorously, thus ensuring the visual effect of the torch. In this way, even in windy weather, the pre-combustion chamber buried under the top of the torch will not be affected and the flame will continue to burn.
