Abstract

UN SISTEMA (12) DE FUEGO TANGENCIAL DE NOX BAJO INTEGRADO QUE ES PARTICULARMENTE APROPIADO PARA EL USO CON HORNOS (10) DE QUEMADO DE COMBUSTIBLE SOLIDO PULVERIZADO, Y UN METODO DE MANEJAR UN HORNO (10) DE QUEMADO DE COMBUSTIBLE SOLIDO PULVERIZADO EQUIPADO CON UN SISTEMA (12) DE ENCENDIDO TANGENCIAL DE NOX BAJO INTEGRADO. EL SISTEMA (12) DE ENCENDIDO TANGENCIAL DE NOX BAJO INTEGRADO CUANDO ES ASI EMPLEADO CON UN HORNO (10) DE QUEMADO DE COMBUSTIBLE SOLIDO PULVERIZADO ES CAPAZ DE LIMITAR SUS EMISIONES DE NOX A MENOS DE 0.15 LB/106 BTU, MIENTRAS TODAVIA MANTENER EL CARBON EN INCLUSIONES A MENOS DEL 5% Y LAS EMISIONES DE CO A MENOS DE 50 PPM. EL SISTEMA (12) DE ENCENDIDO TANGENCIAL DE NOX INTEGRADO INCLUYE MEDIOS (62) DE SUMINISTRO DE COMBUSTIBLE SOLIDO PULVERIZADO, BOQUILLAS DE TOBERA (60) DE COMBUSTIBLE SOLIDO PULVERIZADO DE ACOPLAMIENTO DE LLAMA, TOBERAS DE ENCENDIDO CONCENTRICAS, AIRE SECUNDARIO (98,100) ACOPLADO DE CIERRE, Y AIRE SECUNDARIO (104,106) SEPARADO DE MULTIRELEVO.
