This work presents a numerical study of wood pyrolysis in a parallelepiped carbonizer equipped with a chimney and clay insulation to enhance charcoal yield. A thermal energy recovery system, consisting of six steel plates connected by five rods, was integrated to explore the potential for electricity generation. Simulation results indicate that the chimney exhaust temperature reaches approximately 350 K, making it suitable for drying or biomass preheating. The hot side of the final plate, intended to host a thermoelectric module, can reach a temperature of up to 443 K. Under these conditions, the TEG1-PB-12611-6.0 module can generate up to 3.97 W.
