Abstract

EN UN PROCESO PARA REDUCIR LA EMISION DE NO SUB X DURANTE LA COMBUSTION DE COMBUSTIBLES SOLIDOS, LOS GASES DE DESPERDICIO EXTRAIDOS DESDE LA ZONA DE COMBUSTION PRINCIPAL (2) FLUYEN A TRAVES DE DOS ZONAS DE REDUCCION CONSECUTIVAS (6, 9). LA PRIMERA ZONA DE REDUCCION (6), A LA CUAL SE AÑADE UN COMBUSTIBLE DE REDUCCION, ES SUSTOIQUIOMETRICALMENTE OPERADA A TEMPERATURAS POR ENCIMA DE LOS 1000 C Y LA SEGUNDA ZONA DE REDUCCION (9) ES SUPERESTOIQUIOMETRICAMENTE OPERADA A TEMPERATURAS DESDE 950 A 1000 C Y EN LA PRESENCIA DE SUSTANCIAS REDUCTORAS DE NO SUB X.-
