However, black smoke can appear grey when it is mixed with moisture from other heated materials.

Common Wood Stove and Firplace Backdraft Smoke Issues

Does white smoke mean the fire is still burning?

White smoke can often mean material is off-gassing moisture and water vapor, meaning the fire is just starting to consume material. White smoke can also indicate light and flashy fuels such as grass or twigs. Thick, black smoke indicates heavy fuels that are not being fully consumed.

What does grey smoke mean?

Blue or Grey Smoke

If the smoke from the exhaust pipe is either grey or bluish-tinged, it generally means that your engine is burning oil inside the combustion chamber. Burning oil could be due to a number of causes, from leaky valve seals to bad piston rings.

Does smoke mean creosote?

When the oils in the wood aren't completely burned, they off-gas as volatiles and travel up through the smoke. The smoke cools as it rises, and ultimately condenses with water and other chemicals on the interior of your chimney and flue. This residue is called creosote.

Why is my chimney blowing black smoke?

The After Fire

Even after the burner cycles off, accumulated oil in the firebox continues to burn, causing what is known as an after fire. Once the burner is off, the fan stops running and oxygen is no longer delivered to the flame. An oxygen-deprived flame generates thick, black smoke that exits the chimney.

How do I fix blue exhaust smoke?

Why is wood smoke white?

White Smoke = Initiation of Heat

Virtually all solid materials exposed to combustion emit white smoke. This means heat is being stimulated to the wood and drying it out. Remember, moisture is water and when heat finds water it has to induct it to produce steam.

How often does chimney need to be cleaned?

HETAS encourage having your chimney swept at least twice a year when burning wood and at least once a year when burning smokeless fuels. The best times to have your chimney swept are just before the start of the heating season and after your stove has not been used over a prolonged period.

How do I make my fireplace less smoky?

Why is my exhaust smoking white?

Does a chimney fire damage the chimney?

Chimney fires are dangerous because they can rapidly spread to other areas of the home, putting those within the home at risk of injury or death. Not only that, but they can cause a lot of damage to the chimney itself.

What causes black smoke from a wood fire?

SMALL AMOUNTS OF SMOKE IS A GOOD SIGN

Dense, black smoke is a sign that the combustion is not optimal, usually because the fire in the wood stove is not intense enough. When the wood stove burns optimally, only a bit of steam and some light, odour-free smoke escapes from the chimney.

What's the most common cause of puff back?

Will a hot fire remove creosote?

One method to loosen crusty or tarry creosote so it flakes off and falls down into the firebox or fireplace is to burn aluminum cans in a very hot fire. While this method works, it does not clean the chimney of creosote completely, and chimney brush cleaning is still necessary.

How can I tell if my chimney needs cleaning?

How do you know if you have creosote build up?

Why is smoke white or black?

In general, a hotter fire will convert more fuel into elemental carbon, which forms into tiny particles that absorb light and appear in the sky as black smoke. A cooler combustion—or one that doesn't work as efficiently—yields less-pure forms of carbon. These tend to reflect light, making the smoke look white.

What does Brown smoke mean?

Brown smoke indicates unfinished wood burning. In lightweight construction, this can be a warning sign for building collapse.

What does yellow smoke mean?

Some fuels, such as alcohols and cellulose (cotton or paper, for example), contain oxygen and tend to burn cleanly when air diffuses into the flame. Insufficient oxygen can also lead to a yellow flame because unconverted carbon particles glow yellow hot.

What does color of flame tell you?

Color tells us about the temperature of a candle flame. The inner core of the candle flame is light blue, with a temperature of around 1670 K (1400 °C). That is the hottest part of the flame. The color inside the flame becomes yellow, orange, and finally red.

How do you read fire smoke?

Thin, black, fast smoke indicates a well-ventilated fire is nearby. Slow, white, dissipating smoke (first thick but thinning quickly) is a sign of steam, and indicates early stage heating. Brown smoke indicates unfinished wood burning. In lightweight construction, this can be a warning sign for building collapse.
