FUEL: Given the right circumstances, most substances will burn or combine with oxygen in combustion, a chemical process that liberates heat. (Remember that fire is the heat and light resulting from combustion.) However, the temperature at which things will burn in fire pits, called the ignition point or kindling point, varies according to the substance. For example, the kindling point of film, nitrocellulose, is only 279 degrees Fahrenheit - not recommended for use in fire pits. For wool it is 401 degrees Fahrenheit - obviously making fire pits hard to light, and for newsprint 446 degrees Fahrenheit - perfect for fire pits. What Fuel should I use in my Fire Pit? Wood or charcoal can be used in most fire pits. Some fire pits run on gas, a great alternative. See Artistic Fire Pits for converting your fire pit to gas.
The build 1. The first task is to find a suitable location. This should be away from buildings and other flammable materials and vegetation. The area should be generally flat and well drained. 2. Next, sand or chalk should be used to make a visible impression of the pits shape on the ground enabling the pit to be excavated. The base of the pit should be made of at least 6 inches of concrete, or better still 6 inches of compacted hardcore with a further 6 inches of concrete on top. This would require a dig of about 18 inches. This should require nothing more than a spade. Important: If you intend to build the "fire pit wall" on a concrete base, then the pit diameter should be adjusted to allow for the additional width of the fire pit wall. This will save the need for a separate footing. 3. Once the fire pit base is complete and the concrete has set, it will be possible to build the fire pit wall. The wall will run around the perimeter of the fire pit and enclose it. This wall may be made of loose-laid stone or brick, or of mortar bonded masonry. If the latter is the case, then an additional mortar layer can be used to line the internal surface of the wall. In either case the stones or bricks should be staggered for stability and appearance. 4. Whilst this completes the main fire pit project, pavers, paving slabs, cobbles or brick sets can be used to create a clean and hard wearing surface around the fire pit. Additionally, a simple but attractive seating area can be built around the fire pit by using the same style of stones or bricks to make a basic flat topped bench.
Fire pits are something that can be used and enjoyed all the year, it is true that in the winter the use of fire pits and fireplaces has much more sense due to the fact that these tools can be used to heat up rooms and save some costs on electric or gas heating, an efficient fireplace can heat a large room, without the need to use any other energy source for heating. Fire pits can be permanent or portable. They serve as containers for barbecues, bonfires, as well as outdoor heat. They also come in different sizes, sources and accessories. Some fire pits use wood while others use natural gas. Several fire pits are also designed to roast marshmallows while others can carry out a more complicated function such as container of a bonfire during a camping adventure. In selecting a fire pit, it is best to weigh the pros and cons. If you wanted a portable fire pit, choose a lightweight fire pit that can be assembled easily. If you want a fire pit for your patio, better use a dish or bowl design. Be sure that fire pit special products like screen dome or cover are part of the package. Also consider the size of the equipment especially when you intend to use logs and coals. When you are purchasing a fire pit with grill, make sure that there is an attached tool to raise the grill.
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.
