Each and every day people wonder what certain technology term’s mean, today you will be able to learn what a Primary Flow, Secondary Flow and a Tertiary Flow is.
A Primary Flow is where all smokeless fuels require air to flow beneath the coal which happens via the primary air intake.
Another good example for having a primary air flow is that it actually helps you light the fire as well as keeping those non wood fires burning brightly throughout the day.
A Secondary Flow introduces an airflow around the back and the top of the stove, when the stove heats up it circulates down the surface of the glass which is called a Actiview System than will later be described further on.
The Secondary Flow is a great little system that uses the heated air to prevent the smoke coming into contact with the stoves glass meaning that it allows a perfect view each day. As the air then continues to circulate around the burning fuel it then combusts unburned volstile gasses for a cleaner burning.
Most latest stove models have a series of air holes that have been punched into the back of the fire box, the reason this has been done is so that it allows small jets of air to pass through and ignite sending spurts of flame into the heart of the fire to enhance combustion.
Another way to regulate the rate of the burn is by using the slide controls, one opens the primary air intake and the other regulates the secondary intake.
