Fireplaces

Yes, gas logs can wear out over time due to use and exposure to heat. The ceramic fibers or refractory material that make up the logs can deteriorate, leading to cracks, warping, or discoloration. It's important to inspect them regularly and replace them if needed to ensure safe and efficient operation.

A twin-tube damper consists of two concentric tubes with the inner tube containing the piston and valve assembly while the outer tube acts as a reservoir for the hydraulic fluid. When the piston moves in response to vehicle suspension movements, hydraulic fluid is pushed back and forth between the two tubes through the piston's valves, controlling the rate at which the suspension moves and providing damping to control bounce and jounce.

Chimney use to remove the flue gases and smoke from the building and from the boiler, furnace, fireplace, stove to outside atmosphere. Chimney construct as much as possible in the vertical shape to remove the smoke outside easily. Romans used hole in the bakeries to remove the smoke outside but real chimney found in Northern Europe in 12th century.

A fireplace doesn't do much... it is just a solid, primarily made of brick and steel. However, if you actually burn a fire in a fireplace, you are doing a chemical change on the matter.
__________

The simple version is, if something is burning in the fireplace, chemical energy is being converted into thermal energy via combustion.

Chemical energy -> Combustion -> Thermal energy

A fireplace provides thermal energy in the form of heat and light. When wood or gas is burned, chemical energy stored in the fuel is converted to heat energy, which warms the surroundings.

Bernoulli's principle - the pressure on the top of the chimney would decrease, due to the speed of the air.

No. At least not inside. I was told by poison control after I had gotten carbon monoxide poisoning by burning a combination of store bought manufactured fire logs and real camphor wood. It was bad!

The wood in a match can burn at temperatures exceeding 1,000 degrees Celsius (1,832 degrees Fahrenheit).

A coil spring damper is used in a vehicle's suspension system to absorb shocks and vibrations from the road surface. It helps to provide a smoother ride by controlling the movement of the suspension and minimizing the impact of bumps and potholes. Additionally, the coil spring helps to support the weight of the vehicle and maintain proper ride height.

The chimney sweep who came over used a white, abrasive lotion-like substance (probably available at fireplace shop) and spread it liberally all over the glass and scrubbed. Worked extremely well.

Try this:

1. Get a super-absorbant tampon.

2. Get a blowdryer.

3. Place tampon over wax spill.

4. Turn on blowdryer to hot full and heat up the pad. The wax will be sucked in.

Possibly balsa wood. Incredibly light, but not very strong. Check hobby shops for small pieces.

The spark temperature produced by a piezo igniter is typically around 1800-2000 degrees Fahrenheit. This temperature is sufficient to ignite the pilot light on a natural gas fireplace, as natural gas requires a high temperature spark to ignite.

Not possible to give you an answer, since weight will vary greatly based on the size of the logs (big logs= big air spaces between them) and whether it is dry or green. Small green pinion may weigh 4500 lbs per cord, dry large unsplit wood 2500 lbs.

This is why firewood is sold by volume (cord being 4'x4'x8') and not by weight.

The warmth you feel when standing beneath a heat lamp is an example of radiant heat transfer. The heat lamp emits infrared radiation, which travels in waves and is absorbed by your body, resulting in the sensation of warmth.

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.
