Abstract

The smoke generated in the carbonization process contains various pollutants which are harmful to humans and also contribute to the greenhouse effect. In this scenario, the aim with this research was the construction and evaluation of a system for burning gases from carbonization, which would help decrease the emission of pollutants and the co-generation of energy, making the process more efficient in terms of technology and environment. The study was conducted in partnership with ArcelorMittal Bioenergy. A rectangular laboratory scale oven was built with capacity of 10 wood stere, with furnace for gases combustion and chimney. The oven and the furnace were constructed with four laterals openings to control the carbonization and entrance of oxygen into the combustion chamber for gas burning, respectively. The carbonization gases went through a connection between the furnace and the combustion chamber, where the gases burning occurred. It was observed that during the burning of the gases no visible smoke was released into the chimney as occurs in traditional systems. The system for gases burning did not change the charcoal gravimetric yield and is efficient in terms of reducing emissions, decreasing in 96% and 93% methane and carbon monoxide, respectively. That way the hot air produced can be reused in the form of thermal energy.
