The principle of the Free Flame oil combustion is based on rapid gasification of the fuel by recirculating the combustion gases internally and allows the fuel-air to mix quickly. Once the fuel has been vaporized, it will burn and stabilize 30 centimetres from the combustion head.
The flame appears to “float freely” hence the name “Free Flame”. The heat absorbed by the gasification oil will cause a significant drop in the flame’s temperature and a decrease in the formation of the thermal nitrogen oxide.
