Smokeless fuel is a type of solid fuel that emits little to no visible smoke during combustion. It is designed to reduce the amount of noxious smoke produced and remove impurities such as sulphur in the coal. Smokeless fuels are typically harder to ignite due to the lack of volatiles present, and they have a higher ash content. The amount of smokeless fuel needed depends on various factors, including the size of the property, house insulation, stove efficiency, fuel efficiency, usage, and weather conditions. It is important to use smokeless fuel properly to get the best results and avoid common issues such as restricted airflow, which can lead to poor combustion and reduced heat output. The type of fuel and appliance used may also be regulated in certain smoke control areas.

Smokeless fuel is more expensive but lasts longer than wood
Smokeless fuel is more expensive than wood, but it lasts longer and burns more efficiently. Smokeless fuel is a type of solid fuel that emits little to no visible smoke during combustion. It is designed to reduce the amount of noxious smoke produced and remove impurities such as sulphur, which can be harmful to the environment. The Clean Air Act of 1956 was passed in response to the Great Smog of London in 1952, which killed thousands of people and caused accidents due to low visibility.
The development of smokeless fuels was a direct consequence of this tragedy, and their use has led to improved air quality and fewer annual smoke-related deaths. Examples of smokeless fuels include anthracite, coke, charcoal, and hexamine fuel tablets, which are usually supplied as standard pillow-shaped briquettes. Smokeless fuel has a higher calorific value than dry wood, indicating greater energy content and a more efficient fuel source. For instance, anthracite has a calorific value of 32.5 MJ/kg compared to dry wood's value of 21 MJ/kg.
Smokeless fuel is harder to ignite due to the lack of volatiles, and it produces fewer flames. It also tends to have a higher ash content, but the amount of fines and dust produced is minimal compared to bituminous coal. Smokeless fuel is more expensive, with a premium of about 30% over coal prices in 2020. However, this extra cost is due to the mass manufacturing process, and the loss of volatile chemicals can offset these costs for manufacturers.
To save money, it is recommended to buy smokeless fuel in bulk during the summer, as prices tend to be lower, and you can avoid the higher winter prices at garden centres or supermarkets. Additionally, investing in a coal bunker is advised, as it allows your smokeless fuel to air dry, and you can buy in bulk and store it conveniently near your house. Proper usage of smokeless fuel is essential to get the best results. For example, mineral fuels like coal require airflow from below to combust, so restricting airflow will result in poor combustion and no heat output.

It's harder to ignite, so avoid frequently topping up your fire
Smokeless fuel is a type of solid fuel that emits little to no visible smoke during combustion. It was introduced in the 1950s to curb pollution and smog, and it has since gained popularity as a cleaner alternative to traditional fuels. Smokeless fuel is made from various materials, including anthracite, coke, charcoal, and hexamine fuel tablets. It is designed to burn at a higher temperature, making it more efficient for open fires and stoves.
When using smokeless fuel, it is important to avoid frequently topping up your fire. This is because smokeless fuel requires adequate airflow from below the grate to combust properly. If you constantly add fuel, you may inadvertently restrict airflow, causing the fire to burn at a much slower rate or even fail to catch. Therefore, it is recommended to fill up the stove, let it burn at its own pace, and refrain from frequently interfering with it.
Additionally, mixing smokeless fuel with other types of fuel, such as wood, can lead to premature liner failure. The moisture from the wood combines with the sulphur in the smokeless fuel to create an acid that attacks flues, particularly those made of stainless steel. Hence, it is generally advised to stick to a single fuel type, either smokeless or logs, and burn it hot.
To ensure optimal combustion and minimise smoke emissions, it is crucial to clear the grate and ashpan before lighting a smokeless fire. This allows the necessary airflow to reach the fuel. It is also worth mentioning that smokeless fuel performs differently in various settings. The amount of smokeless fuel required can vary depending on factors such as the size of your property, house insulation, stove efficiency, fuel efficiency, usage patterns, and weather conditions.
Lastly, when it comes to purchasing smokeless fuel, consider buying in bulk during the summer to take advantage of quantity discounts and reduced prices. Buying from local coal merchants can also guarantee friendly service, as they may offer to stack the fuel where you require it or tip it loose into a shed or bunker. By following these tips and understanding the unique characteristics of smokeless fuel, you can optimise your fire's performance and avoid the common pitfalls associated with frequent topping up.

Store indoors, undercover, or in a bunker to maintain quality
Smokeless fuel is a type of solid fuel that emits little to no visible smoke during combustion. It is designed to reduce the amount of noxious smoke produced and to remove impurities such as sulphur from coal. It is typically used as a replacement for fuels like coal, which produce smoke upon burning.
To ensure the quality of your smokeless fuel, it is essential to store it in a suitable location. The fuel should be kept indoors, undercover, or in a bunker. By storing it in this manner, you can maintain the fuel's condition and protect it from the outdoor elements.
Storing smokeless fuel in a bunker is a popular choice for many. A coal bunker allows your fuel to air dry, and it provides a convenient storage solution near your house. Bunkers are also cost-effective, as they help maintain fuel quality and come in various sizes to fit your space.
In addition to bunkers, you can store smokeless fuel indoors or undercover. Keeping the fuel out of direct exposure to outdoor elements will preserve its quality. Whether you opt for a bunker, indoor storage, or an undercover area, the key is to ensure the fuel is not left exposed to the weather or other external factors that could impact its condition over time.
By following these storage guidelines, you can maintain the quality of your smokeless fuel and ensure it burns efficiently when needed. Remember to also consider factors like fuel type, appliance efficiency, and usage patterns when determining how much smokeless fuel you need.

Smokeless fuel is more eco-friendly than wood but is a fossil fuel
Smokeless coal is often marketed as an eco-friendly alternative to traditional house coal. CPL, one of the largest manufacturers and distributors of smokeless coal in the UK, claims that its Homefire range produces 25% less CO2 emissions than regular house coal. This is due to its higher heating efficiency, requiring less fuel to heat a room, and its use of a climate-friendly molasses binder. Ecoal, another smokeless coal product, is manufactured from a feedstock blend containing up to 20% additional renewable materials, resulting in even lower carbon dioxide emissions.
However, it's important to note that coal, including smokeless coal, is still a fossil fuel. When burned, it releases stored carbon that has been locked underground for millions of years into the atmosphere as carbon dioxide. In contrast, burning wood releases carbon dioxide that is already actively circulating in the carbon cycle, and therefore does not contribute to a net increase in atmospheric CO2 levels. As trees grow, they absorb carbon dioxide, and when burned, they release the same amount of CO2 that they previously absorbed. This is why wood is often considered a carbon-neutral fuel.
When it comes to sustainability, wood is generally regarded as a more eco-friendly option than smokeless coal. Wood pellets and briquettes produced by companies like Woodlets are made from sustainably sourced wood and have significantly lower emissions than coal. Additionally, wood is a renewable resource, provided that trees are replanted to replace those used as fuel. However, it is important to ensure that wood is responsibly sourced and properly dried to minimize emissions and maximize its sustainability.
While smokeless coal may offer some environmental benefits compared to traditional house coal, it is still a fossil fuel that contributes to the release of stored carbon. For those seeking the most eco-friendly fuel option, dry and sustainably sourced wood is generally considered a more sustainable and renewable alternative. The key to maximizing the environmental benefits of wood fuel is to prioritize sustainable sourcing and low-moisture content.

It's ideal for open fires and stoves, but not for burning with wood
Smokeless coal is ideal for open fires and multi-fuel stoves, providing a clean, efficient, and cost-effective way to heat your home. It is designed to burn longer than traditional coal, with a gradual and consistent release of heat, resulting in less smoke, less CO2, and more heat. This makes it perfect for those in smoke control areas or looking to reduce their carbon footprint.
However, it is important to note that smokeless fuel should not be used in traditional wood-burning stoves and fireplaces. Burning anything other than logs in these appliances can lead to serious damage and safety risks. Instead, consider using multi-fuel appliances, which can burn both wood and smokeless fuel. These include open fires, stoves, room heaters, cookers, and freestanding boilers.
When using a multi-fuel stove, it is crucial to adjust the air controls based on the type of fuel being burned. When burning wood, the primary air control should only be used during initial lighting or to revive a fire during refuelling. For solid smokeless fuel, the primary air control adjusts the amount of air coming into the fire chamber, and the grate must be regularly riddled to prevent ash-masking.
While wood fuel can be a sustainable and carbon-neutral option, it is important to ensure the wood is properly seasoned and dried. Freshly felled wood can take up to four years to fully season, and kiln-dried wood is recommended to have a moisture content of 20% or less. Burning wet wood can produce more smoke and creosote, increasing the need for chimney sweeping and contributing to environmental concerns.
