Burnout synergic or inhibiting effects in combustion of coal-sawdust blends
The co-firing of coal and biomass was studied using DTG assays. Blends of coal of different ranks and pine charcoal (obtained through pyrolysis of biomass at 1000°C) were prepared. Combustion profiles and characteristic temperatures (IT, PT and BT) were obtained and compared. To detect deviations, t...

Se registraron perfiles de combustión y temperaturas características (IT, PT y BT). Para detector desviaciones en el quemado de las mezclas, se compararon las curvas experimentales de conversión con aquellas obtenidas a partir del promedio ponderado calculado a partir de la conversión de los combustibles individuales y la composición de la mezcla. Estos ensayos revelaron que existen tanto desviaciones positivas como negativas en la conversión. Los factores clave en la predicción de estas desviaciones corresponden a las diferencias de reactividad entre los componentes de la mezcla y su proporción relativa.application/pdfspaUniversidad Nacional de Colombia - Facultad de Ingenieríahttp://revistas.unal.edu.co/index.php/ingeinv/article/view/39473Universidad Nacional de Colombia Revistas electrónicas UN Ingeniería e InvestigaciónIngeniería e InvestigaciónIngeniería e Investigación; Vol. 34, núm. 2 (2014); 29-32 Ingeniería e Investigación; Vol. 34, núm. 2 (2014); 29-32 2248-8723 0120-5609Ulloa, Claudia and García, Ximena (2014) Burnout synergic or inhibiting effects in combustion of coal-sawdust blends.
