It's harder to ignite due to a lack of volatiles
Smokeless fuel is a type of solid fuel that emits minimal to no visible smoke during combustion. It is a potential replacement for fuels such as coal, which produce smoke and cause pollution and health issues. Smokeless fuels include anthracite, coke, charcoal, and hexamine fuel tablets. These fuels are typically supplied in the form of standard pillow-shaped briquettes.
While smokeless fuels offer several advantages, they do have certain drawbacks. One notable disadvantage is their difficulty in ignition due to a lack of volatiles. This results in fewer flames and a higher ash content. The absence of volatile chemicals, such as coal tar, also contributes to the higher cost of smokeless fuels.
The process of igniting smokeless fuel involves specific lighting techniques, depending on the type of fuel and fireplace used. For example, when using a coal-operated fire, one must arrange the coals, clear the grate, and sweep the chimney before ignition. Bioethanol fireplaces, on the other hand, require pouring fuel into a special burner and igniting it with a long lighter.
To address the challenge of ignition due to the lack of volatiles, it is recommended to use dry kindling wood to start a smokeless fire. Ensuring proper airflow is crucial, as smokeless fuels need air from below the grate to combust effectively. Restricting airflow will result in poor combustion and a lack of heat output. Additionally, it is important to note that mixing smokeless fuel with other types of fuel, such as wood, can lead to premature liner failure due to the creation of acidic byproducts.
Overall, while smokeless fuels offer benefits in terms of reduced smoke and improved air quality, they present challenges in ignition due to their low volatile content. Proper lighting techniques, airflow management, and fuel selection are key to overcoming these challenges and maximizing the advantages of smokeless fuels.

Smokeless fuel produces less soot and ash
Smokeless fuel is a type of solid fuel that emits minimal amounts of smoke during combustion. It is designed to reduce the amount of noxious smoke produced and remove impurities such as sulphur, which is a significant hazard to health. As a result, the development of smokeless fuels has led to improved air quality and fewer smoke-related deaths.
One of the benefits of smokeless fuel is that it produces less soot and ash. Smokeless coal, for example, releases 20% less carbon dioxide and burns up to 40% longer compared to traditional coal. With less soot production, chimneys remain cleaner for longer and require less frequent cleaning. The reduced soot also means less staining on clothes, as seen during the Great Smog of London in 1952, which was caused by the presence of toxic gases and soot.
The higher calorific value of smokeless fuels, such as anthracite, contributes to their reduced soot and ash output. Anthracite, for instance, has a calorific value of 32.5 MJ/kg, higher than that of dry wood, which is around 21 MJ/kg. This higher calorific value means smokeless fuels burn at a higher temperature, making them more efficient for open fires and stoves.
While smokeless fuels offer advantages in terms of reduced soot and ash, they also have some disadvantages. They can be harder to ignite due to the lack of volatiles, and they tend to have a higher ash content. Additionally, the cost of smokeless fuels is typically higher than that of traditional coal due to the costs of mass manufacture.
Overall, smokeless fuels, with their reduced soot and ash output, contribute to improved air quality, reduced health hazards, and more efficient heating options. However, they also come with certain drawbacks, including higher costs and potential ignition challenges.
