Resumen

En este trabajo se evalúa el rendimiento de una estufa eficiente de biomasa (IBS) tipo plancha utilizando un modelo de combustión de 6 reacciones para comparar los resultados numéricos con mediciones experimentales de la IBS modelo Tuya. La estufa de biomasa se evaluó mediante una prueba con tres repeticiones (Pruebas 1, 2 y 3) de 40 min cada una, 10 minutos de estabilización y 30 minutos de funcionamiento de la estufa. Se utilizó el software ANSYS Fluent para simular los principales fenómenos de transporte de la estufa de biomasa. En las simulaciones numéricas fueron configurados dos escenarios: TY_6R_L2 y TY_6R_L3 utilizando un coeficiente de exceso de aire (λ) igual a 2 y 3, respectivamente, en las 3 pruebas de rendimiento. En general, los resultados de la comparación de los casos numéricos muestran que λ tiene un efecto significativo en la mejora tanto de la transferencia de calor como del proceso de combustión de la IBS Tuya. En el caso de las emisiones de CO2e se obtuvieron diferencias del 35 y 19% para los casos numéricos TY_6R_L2 y TY_6R_L3, respectivamente, comparados con el valor experimental de 0.68 ± 0.13 kgCO2e/kg.
