Lighter Principle-Process-Skills: An analysis of the content of the windproof principle of the ZIPPO lighter that plans a windshield device to reduce the speed of the air flowing through the flame below a certain level, and the flame can continue to burn. The following content is organized by Maibu.com and is provided for your reference. ZIPPO is the representative of windproof lighters, so much so that when it comes to "windproof lighters" or even "lighters", many people will immediately think of "ZIPPO". So why can ZIPPO be windproof?
When it comes to this, we must first go back and talk about the "three elements of incineration." In middle school textbooks, we should come into contact with this knowledge: Incineration is the process of rapid oxidation of objects and the generation of light and heat. And incineration requires three things to coexist in order to occur, namely combustibles, combustion-supporting materials, and the temperature to reach the ignition point. This constitutes an incineration triangle called the three elements of incineration. If any one of the three elements is removed, the incineration triangle cannot be formed, and the incineration cannot continue. The time to save life is this incineration triangle. Remove one, two, or all of the three elements of incineration to stop the incineration process. Regarding the windproof lighter, what we have to do is just the opposite. We must work hard to maintain the burning triangle so that the three elements are present at the same time. At this time, the lighter can continue to burn.
In life, we often see some knowledge that seems to be opposed to each other. For example, we can blow out candles in one breath, but we also know an idiom called "wind assists fire", so why does this happen? This is because the amount of heat accumulated in the incineration process is composed of different components. Regarding the candlelight, the burning process is gentle, and the heat generated and stored is less. When there is wind, the wind will take away most of the heat of the flame, reducing the temperature of the combustible material below the ignition point, and then burning the triangle. Larger fires, such as forest fires, because there are many combustibles, the burning process is violent, and a lot of heat is generated and stored. Strong winds can't reduce the temperature of combustibles below the ignition point, but bring more combustibles... Air (oxygen) makes the incineration process more violent and the fire spreads faster.
