As secondary burn is about increasing the fuel’s burn rate, maintaining a good flame quality and allowing more air to feed the fuel, it’s often characterized as better being “even with the secondary burn turn on.” However, when turned to “Secondary Burn,” secondary burn area emits hot sparks at an increased rate than primary burn area, therefore subtly altering the stove’s facade appearance.

Are there any environmental benefits to adding secondary burn to my wood stove?

Adding secondary burn to your wood stove can have several environmental benefits, particularly in terms of air quality and carbon emissions. This secondary burn process, also known as staged combustion, involves burning excess wood in a separate chamber or insert before being fully ignited in the main combustion chamber. This staging allows for a more complete burn, releasing more heat and carbon dioxide than a standard one-chamber wood stove setup.

By implementing secondary burn, homeowners can reduce their stove’s overall carbon footprint. Since excess wood is being burned at a lower temperature than if it were left fully unburned, it produces less greenhouse gases (GHGs) and particulate matter (PM). During secondary burn, most of the volatile organic compounds (VOCs) are also broken down, resulting in a cleaner fuel-burning experience. This can lead to a noticeable decrease in air pollution, contributing to a healthier indoor environment and improved overall well-being.

Additionally, secondary burn can also help remove ash and soot buildup from the main combustion chamber, reducing the risk of creosote buildup and periodic stove cleaning. This, in turn, can save elbow grease for stove maintenance and minimize downtime. With proper implementation and maintenance, secondary burn can be a valuable tool in reducing your wood stove’s environmental impact and creating a more sustainable wood-burning experience.
