On a chilly winter's day in 2008, a group of dedicated individuals at ATech, a company specializing in tailor-made electronic solutions, stumbled upon a revelation that would change the course of their company's history.
They learned their homeland lagged a decade behind some other countries in adopting pellet-based heating systems. Undeterred, they embarked on a journey to create a revolutionary furnace rooted in Slovenian expertise and technology.

In the primary combustion zone, combustion begins with three phases: drying, wood gasification (also known as pyrolysis), and initial combustion. During drying, moisture is released and evaporated from the biomass. In the gasification phase, the dry biomass decomposes into volatile combustible gases and char. This stage requires energy input and takes place with an air ratio below the stoichiometric level, meaning there is a limited air supply.
In the secondary combustion zone, the volatile gases are combusted with an excess of air.
At the same time, the remaining char continues to burn in the primary zone. Both processes release energy.
The amount of excess air in the secondary zone is a key factor in controlling emissions of carbon monoxide (CO) and unburned hydrocarbons (OGC). However, a tradeoff exists. If the air supply is too low, CO and OGC emissions increase, although nitrogen oxide (NOx) emissions stay relatively low. With greater excess air, CO and OGC decrease, but NOx emissions rise. Research has shown that biomass burners often emit two to four times more NOx than oil burners.
Many biomass boilers and burners that lack electronically controlled combustion systems are designed to operate with high excess air. More precise air management, using variable-speed fans controlled by CO or Lambda sensors, can significantly reduce emissions. Biomass boilers equipped with Lambda control are considered state-of-the-art, but many systems still only allow for manual adjustments.
Two other important parameters influencing emissions are residence time and combustion temperature. A high temperature and extended residence time can reduce CO and OGC emissions to near zero. However, NOx levels tend to increase with temperature unless the residence time is sufficient.
Therefore, air staging, which ensures high temperatures and long gas retention times, is an effective method for reducing emissions in pellet boilers.
