Abstract
In order to increase the competitiveness of the industrial charcoal production, several authors suggest the utilization of low heating power emissions from charcoaling ovens for the abatement of toxic components in the gases and for the generation of energy, whether it be thermal or electrical. This work presents a proposed methodology for experimental estimation of the mass flow rate of pyrolysis gases from a charcoaling kiln. Based on experimental data from incoming air mass flow rates and temperature variations in a burner prototype on top of a process kiln, an energy balance equation was proposed. Considering the input data for a complete oven run, an average mass flow rate of 0.4 kg/s was calculated during the process. As part of a larger project for the utilization of these slow pyrolysis gases, further analysis are required in order to generate a more precise mass flow rate curve. These results could support future research of charcoaling gas emissions due to the difficulties in precise mass flow measurements and the design of slow pyrolysis gas burners.
