Why can’t the Olympic torch be extinguished by wind and rain? Please, thank you.

Beautiful auspicious clouds, fiery red paint, simple paper scrolls... the "auspicious clouds" of the 2008 Olympic Games torch have a perfect appearance. Under the beautiful appearance, "Xiangyun" beats a powerful "heart". Because the Olympic torch may face various unexpected weather conditions during the relay process, strong winds and heavy rain will severely test the burning technology of the torch. In order to provide a reliable combustion system for the torch, the Aerospace Science and Industry Corporation has contributed a reliable "core" to the Olympic flame. The "core" combustion system consists of three parts: the burner, the pressure regulator, and the gas tank. The burner adopts an innovative double-flame solution, that is, a pre-combustion chamber plus a main combustion chamber. This is the first time in the design of the Olympic torch that the pre-combustion chamber is separated from the main combustion chamber. The flame in the pre-combustion chamber will ensure that the torch "keeps the fire going". Even in windy weather, the pre-combustion chamber buried under the top of the torch will still remain intact. Not affected. The flame derived from the main combustion chamber will make the entire torch burn blazingly, ensuring the visual effect of the torch.
