How To Fix A Chinese Butane Lighter
4th February. 2021, Beijing: The torch design for the Winter Olympic and Paralympic Games were officially released during the one-year inaugural celebration to the 2022 Olympic Wintertime Games.
The Beijing Olympic Winter Torch with the proper noun of "flying" features a similar blueprint to the 2008 Games' master cauldron, which resembled a giant scroll, highlighting the Olympic spirit's legacy in the Chinese capital. The torch spirals upward to resemble two overlapping fluttering ribbons with cloud blueprint covering the handle of the torch.
One of the engineering science highlights of the "Flight" torch is the adoption of hydrogen as the fuel. The torch was designed and has undergone rigorous testing to burn reliably in most weather conditions and to withstand potent winds and farthermost depression temperatures except for the merit of environmental friendless. The other engineering highlight lies in that, the torch is made of loftier temperature carbon-cobweb materials, making the torch light in weight and resistant to loftier temperatures.
"The shell of the torch is fabricated of carbon-fiber materials, revealing the "light, solid and beauty" of the torch; The application bottleneck of carbon-fiber composite materials under extreme weather condition is removed (the torch crush can be normally used in a hydrogen combustion environment higher than 800°C );The trouble of blistering and neat of the torch beat under high temperature at 1000°C during the manufacturing process is solved. ", according to Mr. Huang Xiangyu, a carbon cobweb proficient and deputy general manager of Sinopec Shanghai Petrochemical Co., Ltd.
In addition, according to Mr. Han Zongjie, a senior engineer of Prc Aerospace Scientific discipline and Engineering Corporation, the development of the torch solved several technical problems such equally the flame colour and the stability, high-pressure level hydrogen storage and safe use of hydrogen energy. The torch is provided with high safety, withstands strong winds and farthermost low temperatures and the decompression ration reaches hundred times. Besides the technical problems, the torch also takes into account of the matching requirements of lightweight and miniaturization.
The R&D squad tackled multi technical barriers such as the flame color and stability, loftier-pressure hydrogen storage and safe use of hydrogen energy during the development process of hydrogen every bit a fuel.
The flame color
The flame of hydrogen is invisible in sunlight, which cannot fulfill the visual and photographing demands. The R&D team adult a formula that can conform the flame colour of hydrogen to solve the flame colour problem.
The Stability
In that location will be many high-speed moving scenes or windy environments, particularly during the torch relay of the Winter Olympic. The flame tin be stably burned under the strong wind of 100 kilometers per hour after research and development,.
High-pressure Hydrogen Storage
It is difficult to achieve a large-scale decompression of several hundred times in the limited interior of the handheld torch. A lightweight and miniaturized hydrogen decompression device developed is adult to decompress loftier-pressure hydrogen.
The Tokyo 2020 Olympic Games Torch is also fueled by hydrogen with the theme of "Calorie-free of Hope". On March 12, 2020, the torch was lit in the ancient city of Hera Temple, the birthplace of the ancient Olympic Games.
Hydrogen torches are only minor awarding parts for the Tokyo Olympics and the Beijing Winter Olympics. Toyota hydrogen fuel cell vehicles will be used equally the principal shuttle vehicles for the Olympics and Wintertime Olympics; the Tokyo Olympic Hamlet volition exist fueled by hydrogen by directly importing hydrogen into the Village through the construction of hydrogen surreptitious pipelines.
It is worth noting that, the torch was fueled by propane in the 1964 Tokyo Olympics. After the game, a "kitchen revolution" was set off in Nihon, and gas stoves were gradually popularized. Information technology remains to exist seen whether the "hydrogen energy revolution" can be set off after the Olympics and Winter Olympics.
