What is Afterburn™?

What is Tripleburn®?

Tripleburn® technology is what gives Cleanburn stoves their super-low emission rates. It ensures that the fuel is fully burned, which means there’s less smoke escaping up the chimney.

How Does Tripleburn® work?

The way Tripleburn® works is the way three streams of air are directed into the stove to maximise combustion. Air is drawn in beneath the fuel, above the fuel (passing in front of the glass door), and behind the fuel. This hot air improves ignition so that fuel burns more efficiently, leaving less to be released into the atmosphere.

The Tripleburn® stream technology ensures that air is always directed to the right place. If you’re burning wood, close the grate – the air from above, directed into the heart of the fire, enables optimum burning. For smokeless fuels, open the grate and allow the sir to flow through the bed, which provides the best conditions for these fuels.

Finally, the air stream that passes between the fire and the glass door is particularly important, because it prevents carbon deposits from building up on the glass. Which, as anyone who owns a stove can tell you, will save you a chore on cleaning day.

What Can You Burn In A Smoke Control Area?

If you live in a building in a smoke control area you are legally only allowed to burn authorised fuels, anthracite, semi-anthracite, gas, low volatile steam coals on a fireplace or appliance that is not an exempt appliance. Non-authorised fuels can only legally be burnt in an exempt appliance which has been approved to burn the chosen fuel.
Wood, wood chips and wood pellets are not authorised fuels and therefore to burn these fuels in a smoke control area they must be burnt in an exempt appliance which has been demonstrated to be suitable for burning wood.

Can Oil or other liquid fuels be used in fireplaces / appliances in smoke control areas?

 Oil or other liquid fuel can be used legally in a smoke control area if burnt in any fireplace specially designed or adapted for combustion of liquid fuel.

Can I burn wood, wood chips or wood pellets inside a smoke control area?

Wood, wood chips and wood pellets are not authorised fuels and therefore to burn these fuels in a building inside a smoke control area they must be burnt in an exempt appliance that is exempt when burning wood. It is an offence to acquire any unauthorised solid fuel for use in a building in a smoke control area other than in a building or appliance that is exempt.

Are anthracite, semi-anthracite, electricity, gas, low volatile steam coals authorised fuels for smoke control areas?

Yes, anthracite, semi-anthracite, electricity, gas, low volatile steam coals are authorised fuels.

Can I use kindling, wood, paper and firelighters to start my fire in a smoke control area?

Whether kindling can be used in a smoke control area depends on the way that the original smoke control order was written. Some orders require a gas poker to be used to start the fire while others allow a reasonable amount of kindling wood, paper, firelighters etc,. You should contact your local authority environmental health or protection department for clarification.

Wood, wood chips and wood pellets are renewable fuels, why are they not automatically authorised fuels?

Wood, wood chips and pellets are renewable fuels and the use of renewable fuels reduces overall CO2 emissions. However, the aim of the Clean Air Act is to limit particulate emissions to protect air quality and public health.

An appliance is described as "clean burn", "clean heat" or "low emission" - do these appliances meet the requirements of the Clean Air Act?

The terms "clean burn", "clean heat" and "low emission appliance" are marketing terms occasionally used by stove manufacturers or distributors and provide no guarantee that appliances are exempt or suitable for exemption. The exemption process requires appliances to be assessed in terms of their particulate emissions through the appliance assessment process.

Alternatively, any appliance can be used in a smoke control area if the appliances are only used to burn authorised fuels.

I have been told that an appliance has been tested to EN303-5, does this automatically mean the appliances are exempt?

Appliances that have been tested to EN303-5 may be suitable for exemption however all appliances need to be assessed to become exempt appliances.

Why Should I Burn Wood?

When plants grow they use carbon dioxide from the air to make their wood. If you burn the wood the carbon is released back to the atmosphere. As long as you grow another plant/tree then a stable carbon cycle is set up. So ,the use of sustainable produced wood as a fuel does not increase the carbon dioxide levels in the atmosphere.

What Is A Carbon Footprint?

The carbon footprint is a measure of the exclusive global amount of carbon dioxide (CO2) and other greenhouse gases emitted by a human activity or accumulated over the full life cycle of a product or service.
The life cycle concept means that it is all-encompassing and includes all possible causes that give rise to carbon emissions. In other words, all direct (on-site, internal) and indirect emissions (off-site, external, embodied, upstream, downstream) need to be taken into account.
Normally, a carbon footprint is expressed as a CO2 equivalent (usually in kilograms or tonnes), which accounts for the same global warming effects of different greenhouse gases. Carbon footprints can be calculated using an online calculator.
An alternative definition of the carbon footprint is the total amount of carbon dioxide attributable to the actions of an individual (mainly through their energy use) over a period of one year. This definition underlies the personal carbon calculators. The term owes its origins to the idea that a footprint is what has been left behind as a result of the individual's activities.
Carbon footprints can either consider only direct emissions (typically from energy used in the home and in transport, including travel by cars, airplanes, rail and other public transport), or can also include indirect emissions (including CO2 emissions as a result of goods and services consumed). Bottom-up calculations sum attributable CO2 emissions from individual actions; top-down calculations take total emissions from a country (or other high-level entity) and divide these emissions among the residents (or other participants in that entity).
