How to burn wood

flamesLike other fuels, wood needs plenty of air to burn well. It is best to allow a fresh change of logs to burn freely until they almost turn to charcoal and only then to 'damp' down the fire by reducing the air supply. Filling a stove with logs and damping it down straight away, stops the 'volatiles' from burning and generates a lot of smoke and tar that is bad for health and the environment.

Good burning techniques

The following are recommended to improve the efficiency of appliances and reduce any potential pollution:

• Burn small, hot fires - they produce much less smoke than ones that are left to smoulder.
• Burn seasoned wood. Green wood is a major culprit in the creation of creosote and smoke.
• Burn logs that are 10 -15 cm (4-6 inches) in diameter. Fires burn better with more surface area exposed to the flame.
• Never burn rubbish, plastics, glossy paper or polystyrene.
• Never burn wood that has been taken from salt water. Chlorine combines with the smoke to produce dioxins and furans, which are dangerous carcinogens.
• Never burn treated or painted wood, particulate-board or plywood.
• Store wood outside, off the ground and covered. Bringing green wood indoors to dry can promote the growth of allergy-causing mould spores circulating indoors.
• Use a high-efficiency wood stove, fireplace or insert that is certified to produce low emissions.
• Have the systems installed by a professional and have it inspected and cleaned every year.
• Make sure the fire is getting enough air - check that the air inlet is open wide enough to keep the fire burning briskly, resulting in complete combustion and less smoke.
• Do not damp the fire down (reduce its air supply) until the fuel is reduced to glowing embers.
