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.
OXYGEN: Although there are other chemicals that can combine with fuels to produce heat, oxygen is the most common. The need for oxygen to sustain a fire in all fire pits is shown by the fact that fuels heated in a vacuum will not burn. Sorry there will be no outdoor fire pits in space! CHEMICAL REACTION: There are certain conditions under which fuels will not produce a flame, even though fuel, heat and oxygen are present. For example, if the percentage of natural gas in air is not between about 4 percent and 15 percent, no flame will be produced; your fire pit will not go!
A fire pit is the most basic, but also the most attractive, type of garden heater and it can be built very simply with a limited amount of DIY skill. What is a fire pit? In its simplest form, a fire pit is nothing more than a hole in the ground into which wood or coal can be placed and ignited. Most fire pits are however more involved than this and their design takes account of aesthetics and a more permanent structure. Generally some form of seating or benching, along with a hard landscaped area, are also part of most fire pit projects.
The fire pits popularity is on the rise, many people seem to prefer to have a fire pit at their back yard then invest in bigger and more complicated fire holding elements, the choice is clear since most fire pits are very easy to maintain and take care of, and they do not cost a lot of money, some even produce their own fire pits, letting their imaginations run wild, and their creative side flourish. The summer had encouraged many home owners to seek a fire pit that will serve their needs, some like to use a fire pit as a garden feature and as a source of light in the evenings and night, while they spend time in the backyard, and some use the fire pit for cooking and smoking meat, which does not prevent its use as an element of light as well.
