Contenido principal del artículo

El aumento en las emisiones contaminantes ha generado el desarrollo de tecnologías limpias y alentado el uso de combustibles alternativos como el gas de síntesis. La combustión sin llama es una de las tecnologías limpias más promisorias debido al bajo nivel de emisiones y las altas eficiencias térmicas que permite obtener. En el presente estudio, se llevó a cabo la simulación de un horno regenerativo bajo condiciones de combustión sin llama, utilizando una mezcla combustible de 70% gas natural y 30% gas de síntesis con alto contenido de H2 (en vol.), por medio del enfoque de dinámica de fluidos computacional. Para los cálculos se construyó un mallado simétrico de 405,632 celdas hexaédricas. Los modelos κ-ε estándar, ordenadas discretas y Eddy Dissipation Concept fueron implementados para la turbulencia, radiación y la interacción química – turbulencia, respectivamente. El índice de uniformidad térmica de la cámara de combustión fue de 0.3 y 0.1 para los planos vertical y horizontal respectivamente. Los resultados confirman que es posible obtener el régimen de combustión sin llama en un horno regenerativo usando la adición de gas de síntesis, conservando la uniformidad en la temperatura y la zona de reacción.
