All permanent fire pits have some sort of fireproof material as a surround; it acts as a barrier to prevent people from getting too close and as a buffer to any loose, hot materials that may escape the structure. If you have the space, a wider than normal decking can be easily integrated into the fire pit’s permanent seating, for a setup that mimics this space. Here, a slightly raised surround elevates the narrow ring of the fire pit and offers casual seating for larger gatherings.
Many people opt for a mobile fire pit that can be moved around to various locations. Movable fire pits are certainly less expensive than a built-in pit, come in a wide variety of designs, and have the added benefit of portability. The primary drawback, however, is that a movable fire pit tends to only last a season or two before the materials begin to deteriorate.
Fire pit liners are highly recommended and may be required by your local municipality. In addition to adding a finished look, a steel liner keeps excessive amounts of heat from absorbing into the surrounding stone. By reflecting the heat up and out, it adds to the life of the stone and creates a safer environment. It also increases the feeling of warmth for those around the fire.
The Dakota fire pit is an efficient, simple fire design that produces little to no smoke. As depicted in the illustration, two small holes are dug in the ground: one for the firewood and the other to provide a draft of air. Small twigs are packed into the fire hole and readily combustible material is set on top and lit. The fire burns from the top downward, drawing a steady, laminar stream of fresh air from the air hole as it burns. Because the air passes freely around the fuel, near complete combustion is achieved, the result being a fire that burns strongly and brightly and with little or no seen smoke. The Dakota fire pit is a tactical fire used by the United States military as the flame produces a low light signature, reduced smoke, and is easier to ignite under strong wind conditions.
