| Resumen: | Este artículo presenta la metodología utilizada para elaborar una herramienta computacional para el cálculo del coeficiente de convección efectivo entre la fase volátil y la fase sólida para un horno rotatorio en el que se realiza pirólisis de biosólidos. Se calculan las propiedades del fluido como una mezcla fija de los componentes a la salida de un horno rotatorio. Conociendo las fracciones másicas de los compuestos presentes en el gas representativo, se realiza un modelo matemático para calcular las propiedades dentro del horno a partir del cambio en la altura de la fase sólida y la temperatura de la fase volátil. Considerando lo anteriormente mencionado, se calculó el coeficiente efectivo de convección a lo largo del horno. |
| Abstract: | This article presents the methodology used to develop a computational tool for calculating the effective convection coefficient between the volatile and solid phase in a rotary kiln which pyrolysis of biosolids is carried out. The properties of the fluid are calculated as a mixture of components in the outlet of a rotary kiln. Knowing the mass fractions of the compounds present in the representative gas, a mathematical model is made to calculate the properties inside the kiln by raking into a count the height of the solid phase and the temperature of the volatile phase. Consequently, the effective coefficient of convection was calculated throughout the kiln. |
