Differences between the Golden Fire and traditional wood-burning

Studies have shown that the clean burning of NunnaUuni's Golden Fire produces significantly less harmful carbon monoxide and fewer hydrocarbon emissions, as well as fewer small particles, such as soot, coking coal particles, and ashes. For nature, the most significant are the hydrocarbon and particle concentration in the combustion gases. You yourself notice the difference in burning also, as you breathe fresher air.

Particle concentration in combustion gases* (red. O2 = 13%)**

Particle emissions include the inorganic soot created as a result of incomplete burning, unburnt coking coal particles, and the remaining fine-grained coal – or soot. According to present knowledge, particles can carry toxic substances into the respiratory tract and lungs.

Hydrocarbon concentration in combustion gases (red. O2 = 13%)**

Burning produces numerous hydrocarbons. Not all hydrocarbons are dangerous, but some of them are greenhouse gases or carcinogens. To decrease the quantity of hydrocarbons, it is necessary for the fire chamber to reach a sufficiently high and even burning temperature.
Carbon monoxide concentration in combustion gases (red. O2 = 13%)**


Carbon monoxide, or coal gas, is produced as a result of incomplete burning.
