The basic design The main functional feature of a fire pit is an excavated hole in the ground. This hole is usually circular and has a diameter of not less than 18 inches. Most fire pits will be between 2 and 3 feet in diameter and the base of the pit will be between 6 inches and one foot below the surrounding finished ground level. In order to make the fire pit more functional, more attractive and more versatile, a small wall is built around the perimeter of the pit. This enclosing wall will usually be between 12 to 18 inches high. It acts to contain the fire, tidy up the appearance and radiate and convect heat outwards from the fire pit. A more complete design also supplements the fire pit with some surrounding hard landscaping and masonry bench seating.
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!
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.
Choosing the right spot for your fire pit and safety concerns. Safety should be your main concern when figuring out where to locate your fire pit. Your local code may have specific criteria so make sure you are fully aware of the details. Generally speaking they must be placed in an area away from overhanging trees, bushes or any other combustible materials, structures, buildings or walls. Debris that can easily catch fire or organic material such as leaves, pine needles, dry grass needs to be cleared from an area at least 10 feet from the fire pit. Both permanent or portable fire pits should only be placed on top of fire-resistant surfaces. A layer of gravel or paved area surrounding the fire pit will also help prevent the fire from accidentally spreading.
