If you own a wood burning stove and you’re wondering whether it’s safe and practical to use coal as a fuel source, this article will provide a clear and concise answer.
The Short Answer
Yes, you can use coal in a wood burning stove. Many wood stoves are designed to be versatile and accommodate a range of solid fuels, including coal. However, there are some important technical details and considerations to keep in mind.
Technical Details
1. Stove Design:
The first technical detail to consider is the design of your wood burning stove. Many modern wood stoves are engineered to be multi-fuel stoves, which means they can burn not only wood but also coal, peat, or other solid fuels. These stoves typically have a grate or firebed specifically designed for solid fuels like coal. If your stove has this feature, it’s a good indication that it’s suitable for coal use.
2. Grate System:
A grate system is crucial for burning coal effectively. Coal requires a source of airflow from underneath to burn efficiently. Most wood stoves that can burn coal have an adjustable grate that allows you to control the airflow and burn coal effectively.
3. Airflow Control:
Controlling the airflow in your stove is important, especially when using coal. Coal burns best with a controlled, consistent air supply. Make sure your stove has adjustable air vents or dampers that allow you to regulate the oxygen flow for a stable coal burn.
4. Sizing and Loading:
When using coal, you’ll need to adjust your loading technique compared to wood. Coal burns best when loaded tightly, with space left for airflow. Consult your stove’s manual for guidance on loading techniques specific to coal.
Considerations
While coal can be used in a wood burning stove, there are a few key considerations to keep in mind:
Efficiency: Coal tends to burn longer and hotter than wood. However, it may require a longer startup time and consistent tending to maintain the fire.
Emissions: Coal can produce more emissions than wood, which may lead to creosote buildup in your chimney. Regular chimney cleaning is essential when burning coal.
Quality of Coal: The type and quality of coal you use matter. High-quality anthracite coal is a better choice for wood stoves than bituminous coal, as it burns cleaner and produces less creosote.
Local Regulations: Be aware of local regulations regarding the use of coal in residential stoves. Some areas may have restrictions or bans on coal burning due to environmental concerns.
Conclusion
In summary, you can use coal in your wood burning stove if it’s designed for multi-fuel use and has the necessary features like a grate system and adjustable airflow controls. While it’s a viable fuel source, it requires proper loading and maintenance to ensure safety and efficiency. Be aware of the type and quality of coal you use, local regulations, and the increased maintenance demands when considering coal as a fuel source for your wood stove.
