A fire pit or a fire hole can vary from a pit dug in the ground to an elaborate gas burning structure of stone, brick, and metal. The common feature of fire pits is that they are designed to contain fire and prevent it from spreading.
Above-ground fire pits can be constructed from a variety of materials. The most popular options are brick, natural stone and concrete blocks, such as Belgard retaining wall products. Although design options are endless, most fire pits are either round or square. One reason has to do with the shape of standard fire pit liners.
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.
Although fire pits are often a central part of backyards, portable versions are good options for encouraging more secluded seating nooks. Here, a change in material underfoot -- from gravel to pavers -- marks the quiet square. It is just big enough for a cozy sofa and chair as well as the central fire pit.
