“…The fuel used to power the smoke burner comes from mesquite residue, a tree typical of Northeastern Brazil and, therefore, easily accessible. Furthermore, according to Cavalcanti et al [52], the HHV of mesquite is 18,940 kJ kg −1 higher than the calorific value of several solid fuels of vegetable origin, highlighting the possibility of its use as an energy product. Therefore, substituting the values into Equation ( 28 To calculate the volume of the combustion chamber (V cc ), Equation (29) was employed, according to Melo et al [24]:…”

Charcoal is one of the most essential energy sources in the world and is used mainly for domestic and industrial purposes. Brazilian charcoal production occurs in rudimentary masonry kilns without concern for process safety or energy waste. This work aimed to develop a mini carbonization system of three kilns coupled to a vertical smoke burner for optimized and environmentally correct charcoal and wood vinegar (WV) production on small farms. The project was divided into three parts for dimensioning: the three-kiln set, the WV condensing device, and the smoke burner. The condenser was designed following the procedures from the standards of TEMA (Tubular Exchangers Manufacturers Association); ASME (Society of Mechanical Engineers of the United States) Section VIII, Division 1; and the NR-13 (Regulatory Standard) of ABNT (Brazilian Association of Technical Standards). In contrast to the current scenario, in which primitive carbonization technologies are still employed, bringing about low charcoal yields and significant pollution release, the use of a mini-kiln that allows charcoal production and wood vinegar recovery combined with pollutant smoke burning is an interesting eco-friendly solution. Thus, the mini-kiln model presented here brings a low cost and environmental safety to the charcoal production chain, reaching sustainability parameters and offering higher income opportunities to small producers.
