How Does Chimney Flue Work
That supply of air is dependent on the ability of the chimney to exhaust flue gases as they are created by the combustion occurring in the stove.
How does chimney flue work. Since the lower level fireplace is below the NPP it draws air into the basement through the chimney. How does a chimney work. The warm air will tend to rise drawing the exhaust from the appliance out.
With the chimney cap it looks like there is no opening at all for rain or snow to get in from the top. They work together as a system. How Does a Chimney Flue Work.
This can occur when first lighting the fire and later in the evening when the fire has died down. Chimneys operate on the principle that hot air rises above cold air. Did the chimney guy clog the flue so that heat cant escape.
Ignition is often achieved through a pilot mechanism or manual match lighting depending on the fireplace type. The flue is the metal duct work ceramic piping or brick chimney stack that runs from a. There is nothing to stop rain from going right down the flue.

The chimney drives the system by exhausting flue gases from the stove and simultaneously pulling fresh combustion air into the stove. This is called a draught and it forces air into the fireplace this air feeds the flames as it rushes past the fire. Without a good crown that has been sealed the chimney does not have any protection from rain and snow.
Since soot is a fire hazard it is important to have it inspected yearly and swept by professionals when deemed necessary. For a safe flue a stainless-steel lining must be used to ensure minimal accumulation of flammable debris. A flue without a lining is considered a fire hazard.
The terms flue and chimney are often confused. Where Is The Chimney Flue. The chimney flue is the tunnel that allows smoke and exhaust to exit your home.
The fire down below in the fireplace needs three things to burn continuously oxygen fuel and ignition. This smooth lining cuts down on creosote buildup and protects the brick from premature wear and tear. The movement of hot gases rising from the fire creates a pressure difference between the inside of the flue and the room.
Coming back to the working of a chimney the flue gases released by a fire are hot which means they are dense and so they go up into the flue vent. As air exits the chimney fresh air for combustion is drawn into the appliance. The flue has a secondary purpose of allowing fresh air to enter it which aids in feeding or.
The oxygen is where the chimney flue comes in handy. A flue is a duct pipe vent or chimney that allows the passage of gases from your fireplace to the outdoors. Built of either brick or stone traditional masonry chimneys include a firebox where the wood burns in addition to a flue which is the air shaft running through the interior of the chimney from.
Warmer lighter gasses in the flue tend to move upward. Rising heat creates an air current that carries that heat smoke and gas along an upward trajectory known as drafting and it is exactly how the chimney flue works. When these flue gases rise the low pressure created by the vacuum called the chimney draft draws in the cool air from the surroundings pushing the flue gases outward through the flue.
A continuous supply of air is crucial to maintaining a steady hot fire. A flue liner is typically a terra-cotta lining to the chimney to protect the walls of the chimney form the heat and harsh gasses that need to travel up your flue. It is important to have your chimney flue lined.
Simply put the pressure inside the stove has to be higher than the pressure at the top the flue drawing the smoke up the chimney. To keep the pressure conditions favorable we need a tall column of warm air inside the chimney and cooler air outside. That thing that you call the cap is probably just decorative and is open on the top just like the rest of the flue.
Are you wondering how to clean a chimney fl ue. Either way the flue helps the smoke and other waste gases exit the home. With a very tall chimney the flue gases will often cool so much before they reach the terminal that a cold plug of air is left at the top of the flue and acts like a cork.
Flue Mechanism and Updraft. Fuel may come from gas wood pellets etc. Its function is not to remove hot air but to instead remove hot.
The flue works under negative pressure to draw the smoke gasses and particles from the stove up the chimney and out the top. The flue is the working section of the chimney which takes the products of combustion up and out into the atmosphere while the chimney is a structure built around a core of clay or concrete flue liners terminating with a pot see Anatomy of a Chimney below. It protects your chimney from water and structural damage.
