Whether fire is our friend or foe depends a lot on the way we treat it and our having a basic knowledge of its causes. This understanding will help us see the practicality and benefits of having a Fire Pit. What Is Fire? Although men had been using fire for thousands of years, its true nature was not known until experiments by Antoine Lavoisier and others in the 1700’s showed that fire marks a chemical reaction involving oxygen. I am sure that if they had put outdoor fire pits to good use, they could have figured this out way earlier! Anyway, they proved that oxygen is actually added during the burning process, although others before that had thought that fire resulted from the release of an imaginary substance called phlogiston. Fire is defined as the heat and light that come from burning substances - essential of course for every fire pit.
In describing the basic essentials for fire, many speak of the "fire tetrahedron." In other words, besides the original "fire triangle" of fuel, heat and oxygen, they add the fourth essential of chemical reaction. Fire pits use all four! It is necessary for us to understand the part each of these plays in producing fire so that we can put it to use in either lighting our fire pit and preventing or extinguishing unwanted fires. For example, to put out a grease fire on the stove, turn off the stove (removing the heat) and cover with a lid (removing the oxygen that feeds the fire). This will also benefit those contemplating buying a fire pit, helping them to decide which fire pits are best for them. So to get a better idea of what causes fire in your fire pit, let’s take a look at these four basic elements.
Customize It Or, you can build your own and have it customized to your liking. In this guide, rather than calling it an article, I’m going to tell you how to build your own outdoor fire pit. There are 2 types of fire pits: Wood, or Charcoal burning And Gas Fire Pits The type that you will learn how to build is wood. I’m partial to the wood or charcoal pits cause they are just better in terms of the wood smells and it looks better. To me a gas fire outside is just fake. But, hey they serve the purpose so whatever your choice is you can’t go wrong.
The burning process can be illustrated by an examination of the flame of a candle. The wax does not burn directly, but, rather, gas given off by the heated wax travels up the wick and burns. Prove this by blowing out a candle that has been burning for some time. Then pass a lighted match through the trail of smoke rising from the wick. A flame will travel down the smoke to the wick and relight the candle. There are three areas in the flame produced by fire pits: (1) the dark inner area of no combustion and (2) an intermediate layer of incomplete combustion, composed of hydrogen and carbon monoxide that gradually work their way to (3) the outside cone of complete combustion.
