Fireplaces

The wood in the fireplace has more potential energy because it contains stored chemical energy that can be released through combustion. Once the wood is burned and converted into ashes, the potential energy is mostly depleted, leaving behind mostly inert material with minimal energy potential.

There is no wood that does not burn. All types of wood are combustible and can burn if exposed to high enough temperatures. Some woods may burn more slowly or with less intensity than others, but they are all capable of burning.

I have the same question! Just had my chimney cleaned and the guy said there was no scientific evidence that it helped. For what it's worth, last years chimney cleaner told me to do it because it just might help.

Burning wood in a fireplace does not duplicate Lavoisier's experimental setup because it does not provide a controlled environment for accurate measurements of mass before and after the combustion process. Lavoisier's experiments involved precise measurements and isolation of the gases produced during combustion, which are not typically done in a traditional fireplace setting. Additionally, a fireplace does not typically have the necessary equipment for capturing and analyzing the gases produced during combustion.

The gas orfice when operating creates a vacuum drawing combustion air into the burner. This is the reason that gas pressures vary between types. Natural gas appliances operate at a nominal 3.5" wc pressure, while LP appliances run 10-11" wc. Natural gas has about 1000 btu's per cubic foot, while LP gas has about 2500. As an example, if you were to reduce the manifold pressure of LPG, you would have an oxygen starved mixture that would not burn properly. lc

I have a gas log fireplace that after a period of time the fire as well as the pilot light will go out. What could be the problem?

Thank you,

Linda, I don't know how long ago you posted this, but when you write in THIS area, your question gets routed to the "already answered" bin- I caught it by accident. Your problem is likely due to something with the thermocouple. That is the device that senses heat fom the pilot light- no heat, it turns off gas as a safety measure. Get a gas appliance repairman to check- they do go bad, get bent, etc. Not incredibly expensive to replace.

A cultural hearth is a site of innovation from which basic ideas, materials, and technology diffuse to many cultures.

A cultural hearth is a "heartland", a foundation of a major culture. There are seven main culture hearths which include the Nile Valley Indus Valley, Wei-Huang Valley, Ganges Valley, Mesopotamia, Mesoamerica, West Africa, and Andean America. Many of the ideas and improvements that start up in these hearths spread to other parts of the world. Modern cultural hearths include cities such as London and Tokyo. Other things such as major religions and many inventions have come from the Middle East such as the wheel, plow, sail, and our alphabet. A cultural hearth could also be the early center of civilization.

Wood burns faster than silver because it has a lower melting point and is more flammable. Silver's high melting point makes it resistant to burning at standard temperatures, however, it can eventually melt under intense heat.

There could be several reasons why a gas fireplace won't stay lit. It could be due to a faulty thermocouple, dirty pilot light orifice, inadequate gas flow, or a malfunctioning gas valve. It is recommended to have a professional inspect and repair the fireplace to ensure it operates safely.

Dense wood burns better because it contains more energy in the form of potential heat due to its higher wood fiber content. This allows it to sustain combustion for longer periods of time and produce more heat compared to less dense wood types.

A cord of firewood typically weighs between 2,500 to 3,000 pounds, depending on the type of wood and moisture content.

Yes, the density of wood affects the rate of burning. Denser wood burns slower because it contains more material that needs to be heated up and burned off. Less dense wood burns faster because there is less material to be consumed.

To build a wood-burning sauna, you will need to construct a sauna room with proper insulation, ventilation, benches, and a heat-resistant stove. The stove is typically made of metal or stone and is designed to hold heated rocks for generating steam. Ensure proper safety measures are in place to prevent fire hazards and make sure to follow local building codes and regulations.

Because heat is a big factor in starting and keeping a fire. You have air, and fuel, and the heat is already factored in. The wood that is already there burning helps too because the fact that it is burning means that most of the wood is dry, and dry wood burns much faster than wet or damp wood. Plus, the dry burning wood dries out any new wood that is placed on top of it, making all of the wood dry, which is the same as stacking tinder, as it is already ready to be set ablaze.

Burning a log in the fireplace involves a chemical reaction because it undergoes combustion, reacting with oxygen to produce heat, light, and new chemical compounds like carbon dioxide and water vapor. Sawing a log in half is a physical change where the log is simply being cut into smaller pieces without any chemical reactions occurring.

On mine if you turn the nob clockwise, that openes the damper. If you trun the now counter clockwise that closes the damper. Yours may be different. Let me think. Did you have anything in your stocking this morning?

Fireplace crystals change the color of a flame because of their chemistry of combustion. The crystals have different chemical compounds in them, and each compound gives off a certain color light when it is burned. You experience the wonderful effects of this every year when you watch fireworks. The people who make fireworks know (just as do the people who make fireplace crystals) what chemical compounds will burn with a bright red flame, what ones make the brilliant blues and which the superb greens.

Yes, cherry wood is often used as firewood because it burns relatively cleanly and produces a pleasant aroma. However, it is important to ensure the wood is properly seasoned to avoid excessive smoke and creosote buildup in your fireplace. Additionally, be sure to follow any local regulations or guidelines regarding burning wood for heat.

Yes! For indoor fireplaces simply scoop an upper layer off the top with a strainer and wash it with the garden hose.

For large outdoor fire pits squirt it off with a fan spray than keep a cover on it when not in use.

Tantalized wood is industrially treated with the tanalith preservative. Tanalith treated wood is highly toxic and should not be burned in open fires or in homes. The chemicals released in the smoke and concentrated in the ashes is toxic and causes a variety of flu-like symptoms that vary depending on the severity of exposure.

A few materials that can create a very hot fire include magnesium, thermite, and certain rocket fuels like hydrazine. These materials burn at extremely high temperatures, reaching over 4000 degrees Fahrenheit.

Muriatic acid reacts with cement, concrete, and limestone. It may not be suitable for removing an oil based or water based sealer from these products. If you know what type of sealer it was, contact the manufacturer for information.

No. The safe and proper application of FireCrystals is in fully vented, fireplace (open to room air and vented through the roof) with a gas supply of preferably natural gas, although propane can be adapted with the proper hardware. Exceptions may apply.
