Chimney Fires
It's a known and unavoidable fact that dirty chimneys can
cause chimney fires, which damage structures, destroy homes and injure or kill
people.
Not all chimney fires burn explosively and therefore are not noisy and dramatic
enough to be detected by neighbours or passers-by. With proper care,
chimney fires are entirely preventable and your Chimney Cleaner engineer will
recommend an ideal cleaning schedule to ensure your chimney's safe upkeep. In
addition to keeping your chimney clean there are a few other things you can do
to prevent chimney fires:
Chimney fires burn at about 2000' F which in masonry chimneys can melt the mortar, crack tiles, cause liners to collapse and damage the outer masonry material. Most often, tiles crack and mortar is displaced, which provides a route for flames to reach the timbers of the house. In Pre-fabricated, or metal lined chimneys, damage to these systems can still occur, usually in the form of buckled or warped seams and joints. When pre-fabricated or metal chimney liners are damaged by fire, they should no longer be used and must be replaced.
Causes of Chimney Fires
Solid fuel stoves and fireplaces are designed to safely contain and burn fuel, providing heat for your home. The chimneys that serve them have the job of expelling the exhaust fumes and substances given off from the burning fuel.
As these substances rise up the chimney and cool down, condensation occurs and forms a residue that sticks to the chimney. Usually black or brown in appearance, it is highly combustible and in sufficient quantities can catch alight.
Certain conditions encourage the problem; restricted air supply, unseasoned
wood and cold chimney temperatures (especially external wall chimneys) are all
factors that can accelerate the build-up of flammable residues.
