If your chimney isn't producing smoke while others do, it could be due to the type of heating system you have. Gas heating systems typically burn cleaner than wood or coal, producing little to no smoke. Additionally, your chimney may be well-designed for ventilation, preventing smoke buildup or backdrafts that can occur in less efficient systems. Proper maintenance and clean flues also play a crucial role in ensuring optimal chimney function.

What is it called when hot smoke gases up and go to the chimmeny?
This process is called "flue gas exhaust," where hot smoke gases from a fire or combustion process are directed up a chimney or flue to be released into the atmosphere.
Is gas from chimney more dense than pure gas and why?
Generally speaking, any gas emitted from a chimney, or any fire, is going to be denser than pure gas, that is gas that has not been burned. This is due to the impurities of the fuel being used to cause the flame. Impurities that are vaporized by the heat rise with the gas, making it more dense. Also, when burning something, especially wood for instance, there are many microscopic particulates that are emitted into the chimney (also, think diesel truck exhaust). This is soot. These particulates are not gases but rather solids, but they are suspended in the gas. If measuring the density of what comes out of your chimney, some of it would be due to these particulates. Pure gases do not have any particulates of course. Finally, when comparing the density of two gases (now neglecting the contribution of particulates), it is important to consider the molecular mass of the gases. For instance helium (He) gas is lighter than air (which is mostly nitrogen gas (N2) and oxygen gas (O2). Two samples (of the same volume) of gases at the same pressure and temperature will have nearly identical numbers of molecules (according to the Ideal Gas Law). So if those molecules have greater molecular mass, then the sample will be heavier. If the sample is heavier but the volume is the same, then the density is greater (density is after all just mass per unit volume). So, when you compare the emissions from a chimney to a "pure gas" it really depends on which gas you compare it too. Pretty much all gases are more dense than hydrogen gas (H2), but very few are as dense as say xenon gas (Xe) or radon gas (Rn) for instance. So, all that said, if chimney gases are more dense than say air, why does smoke rise? It rises because it is hotter than the air around it. Because it hot, it does have a lower density than air! The point is that if you compare them at the same temperature and pressure, the smoke will be more dense. But if you compare hot smoke with room-temperature air, the change in temperature makes enough of a difference such that the density of the smoke is lowered, and so it rises. This is why a chimney won't pull as well when it is hot outside. When it cold, there is a big difference in temperature between the air and the smoke, and so the smoke is much less dense. When it is hot out, the temperatures are closer to each other, and so the densities aren't so different, and the smoke doesn't rise as easily.
Is somke a gas?
Yes, smoke is a gas among other things. Smoke is a combination of solid and liquid particles as well as gases.Smoke is not a gas, though there can be gasses present in smoke depending on what kind of smoke it is. What we see as "smoke" is really a fine collection of soot and ash floating in an air current cloud.
Does smoke made by humans heat up Earth?
Smoke and those emissions we usually regard as pollution have very little effect on global warming. It is carbon dioxide, often associated with smoke but actually a colourless and odourless gas, that is the main man-made cause of global warming.
Which travel faster smoke or gas particles?
gas particals
How does a fireplace heat the room?
A fireplace heats a room by radiating heat from the burning wood or gas. The heat warms the surrounding air, which then circulates throughout the room. The chimney also helps to draw in fresh air and remove any smoke or fumes.
What is an opening for fume or smoke to escape mean?
a vent
Is CO2 gas in smoke?
Yes, along with water gas and soot [and Heat].
Can a pellet stove insert be used in a gas fireplace?
No, a pellet stove insert cannot be used in a gas fireplace. They are designed for different types of fuel and operate differently. It is important to only use the appropriate type of insert for your fireplace.
Can you burn wood in a gas fireplace with a chimney?
No, it is not safe to burn wood in a gas fireplace with a chimney designed for gas.
Does a gas fire leave smoke?
When it burns gas a gas fire produces hot invisible poisonous fumes that include the odorless gas Carbon Monoxide. Those fumes must be vented to the outside of the building using a good chimney or a properly designed flue pipe otherwise they can easily kill you.If a gas fire is properly set up it should not produce any visible smoke at all so if your gas fire is producing smoke you must urgently call a licensed gas fitter to fix the gas firefor you.If visible sooty smoke comes off a gas fire that could be as dangerous to your health as the normal odorless and invisible fumes produced by a properly set up gas fire which vents them through a proper flue pipe or chimney.

Can Fireplace pull heated air from room?
All fires needs oxygen to burn and heat rises. So, the fire will pull air into it and the heat and smoke will then go up the chimney. The result will be heat loss from the house, however, here will also be some heat added from the radiant heat of the fire. If you really want to get heat from a fireplace, the best thing you can do is install a wood, gas, pellet or some sort of bio-fuel insert into it.
Why does the gas log fireplace not heat a room?
It's most likely a woodburning/vented fireplace, by design the combustion air used to burn gas logs comes directly from the room, and all the fumes/hot air go up the chimney. The fireplace actually pulls outside air into the home to replace the air lost up the chimney. All the heat is radient, so if nothing is there the feel the heat, it is lost.
Which generates more heat a wood or gas fireplace?
Well is the question the total amount of heat, or total USEFUL heat? In general, a wood fire burns a bit hotter than gas- hence the wood fired pizza ovens. Hoever, gas fireplaces usually have a heat exchanger that draws in room air, warms it, and returns it to the room. It has less air going up the chimney than a wood fireplace (a major point of heat loss) The chimney of a wood fireplace may be more massive brick, which will hold heat after the fire burns out.
What comes out of chimney?
It depends on the fire, but if the fuel is largely organic matter and the amount of air is not restricted, the gas from the fire will be largely carbon dioxide and water vapor.
