How Does an Asphalt Chimney Catch Fire?

Chimneys are air-filled structures in a structure like a house, building or a verandah that exude heat or draw cool air from a living space to the outside. A chimney is also an architectural venting system made entirely of clay, masonry or metal that encloses hot toxic combustion gases or smoke produced from a furnace, stove, boiler, incinerator or fire in warm areas. These chimneys are usually built with a clay tile or metal, which reflects and heats the incoming air.

 

There are different types of chimneys including conventional wood burning, gas, electric, water heater or ventless. These have varying ways of venting and therefore contribute to different types of emissions. A conventional wood burning chimney usually has a stack of bricks or tiles that are built up over a central chimney. The chimney cap, which is often made from clay, allows the exhaust gases to flow straight into the chimney. These chimneys are easily maintained and can be put on display.

 

When it comes to the issue of chimney fires, a lot of emphasis should be placed on prevention rather than on cure. This is because the main cause of chimney fires is creosote. Creosote, a fine, dry, brittle material, easily combusts in the open and releases harmful gases into the atmosphere. The main threat posed by chimney fires is due to creosote being released into the air after the chimney has been burning for a long time. The main way to prevent chimney fires is to stop smoking habits. Another way to ensure that creosote does not spread to surrounding areas is to install certified chimney caps.

 

As most chimneys are open, they require indirect access to the air. This is done through a chimney cap which is attached to the top of the chimney, either by welding or stainless steel screws. A chimney cap prevents creosote from entering directly into the fireplace. Even if there is no creosote present, a chimney cap will still prevent the entry of harmful gases from the outdoors.

 

Another way to ensure that chimneys function properly is to regularly maintain them. It is advisable to get a chimney inspection by a professional chimney sweep at least once a year. The sweep’s main job is to check for cracks and creosote buildup. In addition, if there are any defective parts on the chimney, they must be repaired right away. If you are having regular maintenance with prefabricated chimneys, it is advisable to also get chimney parts such as gaskets and flues checked by professionals once in a while.

 

The performance of your chimney can also be affected by various weather conditions outside. For example, wind, rain, snow, dew, and extreme temperatures can damage the inner walls and other parts of your chimney. As such, it is always important to maintain the proper functioning of your heaters and other fireplace equipment so that they can give off adequate heat for the home.

 

There are also some masonry chimneys that can be affected by cracks caused by water seepage. Cracks can appear anywhere around the masonry chimney walls and may even appear inside the walls if they are not maintained properly. When this happens, water can build up and cause damages to the inside of the house. However, proper maintenance can help to prevent this condition from arising.

 

In the past, masonry chimneys were not preferred due to their poor fire quality. This problem has now been addressed by the use of ceramic tiles along with steel mesh inside the chimney. This allows smoke to pass freely through the room while providing a source of aesthetics as well. Overall, these metal chimneys have an excellent aesthetic value. They are affordable and can easily be installed on the exterior walls of a home.
