The fire in a fireplace burns well when it is drawing well, which means it is getting a steady flow of fresh air (& oxygen) to the fire and exhaust/smoke is flowing steadily away. An open fireplace in a building needs quite a large volume air to be supplied to it (either from a draughty or well ventilated room, or through a vent), and a large exhaust through the chimney.
The wind around the building can affect the drawing of the chimney by creating high and low pressure areas. If the chimney top is in a lower pressure area than the room with the fireplace, the air will draw steadily through the fireplace and chimney, because air in a high pressure zone will want to flow to a lower pressure zone. If the chimney top is in a higher pressure area than the room, the flow will tend into the room, bringing the smoke with it.
Wind direction and speed can affect this, as can the position of the chimney opening and the ventilation of the fireplace room. A well designed fireplace should draw well in all wind strengths and directions, but many do not.
Hi, We live in Aylmer Quebec, and my question is about outdoor fireplace or firebox, can we burn wood?
On windy days, the wind passing over the top of the chimney draws more air up the flue. This draws more air from the house into the fireplace, providing more oxygen to the fire, causing it to burn more intensely.
Cleaner and hotter burn
It is better to burn only untreated hardwoods (pine, oak, mesquite) in your fireplace. Others leave residues or release unwanted chemicals.
no, you'd better not, it may be harmful to you and your family!!
a sun burn on a windy day
Yes you can! Maple is one of the better fire woods to burn. Just make sure it's dry & not green wood.
Yes you can. I would not advise to burn in an indoor fireplace due to chemicals used on the wood and also because of the screws and nails. Also if you decide to burn it never leave it unattended and always burn in a covered fire pit.
Yes it just does not burn well because its a rubbery plant, the denser the fire wood the better for fires generally
You must NEVER burn when it is at all windy, the wind could catch an ember and start a wild fire.
no
Yes it can
