How does secondary combustion work in a wood stove?

Secondary burn works by burning off the initial smoke produced from the fire that otherwise would have gone up the chimney. You will often see a series of holes towards the top rear of the stove above the fire box that forces fresh oxygen over the chamber, reigniting this smoke.

What is secondary combustion in a wood burning stove Why do we need to control the amount of combustion air?

Secondary burn or combustion on a wood stove is the process of burning off waste gases higher up in the stove in order to produce more heat and to reduce emissions. A second feed of air over the fire in a wood stove firebox helps secondary burn to occur.

What does double combustion mean?

All AXIS fireboxes are equipped. The principle consists in injecting oxygen at a certain height of the combustion chamber in order to provoke the combustion of the gases before their release in the atmosphere.

What is secondary burn or combustion on a wood stove?

My parents have wood burning stoves in their living room fireplaces, and both wood stoves have secondary burn functionalities built into them.

Where does the secondary air come from on a wood stove?

Secondary air typically enters the stove through an air vent located above the door, or from underneath the stove, and can be used in the stove’s air wash system or for secondary burn of gases. Tertiary air is fed into the firebox through the back of the stove to aid with secondary combustion and to further reduce emissions from burning wood.

What are the two steps of secondary combustion?

The two steps can be listed as follows: In a secondary combustion wood stove system, optimum efficiency from your wood fire would result in the optimum occurrence of both steps of the chemical reaction.

Why does a wood burning stove burn more wood?

Along with a fresh supply of air to the area above the flames, the high temperatures reached within a wood burning stove helps to reignite the gases, therefore providing more heat output than simply burning the wood alone. Secondary burn typically starts to occur when the stove reaches higher temperatures.
