Abstract
Quemadores proyectados para la combustión de carbón pulverizado y, en particular, a los quemadores que pueden ser utilizados en las calderas calentadas por carbón de los generadores de vapor. De manera más específica, este invento está destinado a un método para encender carbón pulverizado en ausencia de una entrada de energía de consideración obtenida de la combustión de un combustible líquido o gaseoso. El aire y el carbón son introducidos en una cámara de combustión en forma de una corriente, en la que la relación de peso de transporte de aire a carbón es menor de 1,0 y, con preferencia, menor de 0,5. En la mezcla de carbón y aire se da una fuente de energía suficiente para calentarlos reactivos a la temperatura de encendido, con lo que la mezcla se enciende. La fuente de energía de encendido puede ser, por ejemplo, un encendedor de chispa eléctrica. La mezcla encendido es contenida dentro de una región de recirculación, donde los productos calientes de la combustión son recirculados hacia el punto de inyección del carbón y el aire, para concentrar así la energía térmica que se libera y crear una llama autosostenida.
