Abstract

Un aparato de crisol recalentado (10) permite el ajuste de un perfil térmico dentro de una cámara de combustion (12) que rodea el crisol (15) introduciendo una mezcla sub-estequiométrica o super-estequiométrica de combustible y oxidante en la cámara de combustion (12) y variando la mezcla de flujo de oxidante a sub-estequimétrica o de flujo de combustible a super-estequimétrica corriente debajo de la combustion inicial para controlar la liberacion de calor en lasáreas definidas dentro de la cámara de combustion (12). El aparato incluye un suministro de oxidante (54) y combustible (25) en el punto de inyeccion primario (32) seguido por la inyeccion secundaria del suministro de oxidante restante a intervalos específicos para lograr el perfil térmico deseado. Puede proveerse un intercambiador de calor (51) que precaliente el oxidante y un intercambiador de calor (49) que enfríe el material que sale del crisol.
