At some point in our life, we all gathered around a fire or fire pit, as well as fried marshmallows or a bar-b-que grill preparing hot dogs or burgers with friends and family.
However, the risk of forest fires led to the fact that the US authorities began to impose lasting bans. In many states, extended fire bans in different seasons. Although they are primarily intended for landowners, they can be extended to your backyard. However, you can still enjoy the warmth of the fire pit, without violating access rights, turning into gas and eliminating wood.
Another consideration for burning gas compared to wood is convenience. It is much easier to illuminate the gas fire shaft in comparison with the lighting of a wood pit or a fire bowl.
Another factor is the elimination of the need to store wood. The tree is extremely bulky, and for some people the wood supply is not aesthetically pleasing.
The last nail in a wooden coffin finds a reliable source of suitable hardwood at an economical price.
So let's take a look at alternatives to fuel for fuel.
Physical characteristics of methane and propane
The gas supply through the gas line to the properties is ninety-five (95%) of methane. The remaining five (5)% is an added odorant, called Mercaptan, which gives a pungent smell to ensure leak detection.
Raw natural gas is a mixture of gases with the most important component of methane. Other gases include propane, butane and ethane, oxygen, carbon dioxide, nitrogen, hydrogen sulfide and some trace inert gases. There is also the amount of water that must be removed to prevent corrosion in the pipeline. When processing raw natural gas, propane and butane are collected.
Methane (CH4) is a colorless, odorless gas that is lighter than air. Methane can be stored in gases to regulate pressure in the pipeline.
Propane is supplied in the form of liquefied petroleum gas (LPG), because when pressure is applied to the propane gas, it is liquefied. It is produced from the processing of natural gas, as indicated above, and from refining. It is best to ship in 20-pound test tubes from your local hardware store and in rural areas in stationary steel steel tanks repaired by local propane distributors.
Propane (C3H8) is similar to methane in that it is a pure, odorless gas, to which ethanethiol odorant is added, but unlike methane, propane is heavier than air.
Energy content comparison
One (1) cc ft. propane contains 2,516 British thermal units (BTU) of energy.
One (1) cc m of methane contains 1030 (BTE) of energy, so propane contains almost 2.5 times more energy than methane.
Cost comparison
This is difficult to determine due to regional price fluctuations, however, since propane prices have increased, methane is more economical than propane, even if you burn more methane for the same heat output.
Type of burner
The burner is located inside the pan at the top of the fire pit.
Two types of gas burner are available:
1. A stainless steel ring burner, sometimes referred to as a candle burner and usually installed on gas fire holes that can be bought at major stores or online.
2. Vortex burners, which create a more realistic flame, are more efficient than ring burners. They can be purchased from specialized suppliers.
Portable and static
Now that we have the technical details, let's consider what options are available. We can classify gas fire pits into portable and static.
portable
1. Stand-alone gas fire holes using a single 20-pound cylinder stored in the metal base of the fire pit. Heat output ranges from 26,000 to 40,000 BTU. The price varies depending on the finish of the upper part of the fire pit and other functions, including electronic ignition, hidden controls, etc. D. Weight without a cylinder between 97 pounds - 130 pounds. The price range is $ 300.00 to $ 1,000.00.
2. Patio heaters with a heat output of 46,000 BTU with a height of 87 inches. The base is covered with a cylindrical cap that hides a 20-pound propane-cylinder. Tip over safety device. The heated area is 18 feet. Diameter ranges from $ 200.00 to $ 600.00.
Static fireplaces
Static fire pits can be powered by the supply of methane or propane, as well as 20 pounds of propane tanks. All fire pits for pipelines must be installed by a certified specialist.
1. Converting an existing fire brick or stone fire pit.
To do this you need the following:
a]2 ", slightly smaller than the hole at the top. The pans are supplied with a diameter of 24 inches, a diameter of 30 inches and 36 inches with a price range of $ 290.00 and $ 450
b]Burner with heat output in accordance with the burner pan at 60 K BTU, 120K BTU and 180K BTU with price ranges from $ 190.00 to $ 390.00
from]Gas connection kit with valves
d]Diffusion material, lava stones, fire glasses, fire beads, and fire log kits.
2. Metal fire pit kits.
The frames come in octagonal, round, square, rectangular or non-standard shapes, covered with a fire-resistant concrete fiber board, a frying pan and a burner, all gas compounds. For an additional fee, a choice of hood and side trim is offered. Due to the almost unlimited variations, we cannot give a range of prices.
3. Sets of concrete rings.
Sets come in an octagonal, round, square and rectangular shape with a choice of size. Requires assembly at the site and finishing with stone and side material. All brackets, burners, gas compounds and diffuse materials are supplied. The price range is $ 2000.00 to $ 4,600.00
4. Pre-designed fire pits and fire foci.
Pre-engineered gas fire holes can be purchased in a wide variety of shapes, materials, finishes with a choice of diffusing materials and ignition systems. Price range $ 1,850.00 to $ 5,500.00
5. Conversion of artistic steel fire bowls.
All sculpted 1/4 "steel fire bowls have a 1 1/2" drain hole in the bottom. You can purchase a gas conversion package consisting of a burner plate and a burner. The gas supply is fed through a drain hole to the burner. The package is supplied with all gas supply valves and flexible connections along with the diffusing materials of your choice. Price range $ 749.00 to $ 2,500.00
conclusions
1]Methane is the most economical gas fuel, but it must be installed on a static mine.
2]20 lb Propane-cylinders are the most versatile source of gas fuel that can be used in both portable and static fires.
3]Always check the gas connection for leaks.
4]Never move the portable pit until it has cooled.
