Abstract

SE DESCRIBE UN SISTEMA AVANZADO DE AIRE DE SOBREALIMENTACION PARA CONTROL DE LOS NOX, DISEÑADO PARA USO EN UN SISTEMA DE COMBUSTION DEL TIPO QUE ES PARTICULARMENTE APROPIADO PARA USO EN HORNOS ALIMENTADOS CON COMBUSTIBLES FOSILES Y UN METODO DE FUNCIONAMIENTO DE TALES HORNOS QUE INCLUYE UN SISTEMA AVANZADO DE AIRE DE SOBREALIMENTACION. EL SISTEMA AVANZADO DE AIRE DE SOBREALIMENTACION PARA CONTROL DE LOS NOX, INCLUYE MULTIELEVACIONES DE COMPARTIMENTOS DE AIRE DE SOBREALIMENTACION, QUE SE COMPONEN DE UNA SERIE DE COMPARTIMENTOS DE AIRE DE SOBREALIMENTACION (84, 86) ESTRECHAMENTE ACOPLADOS Y DE UNA SERIE DE COMPARTIMENTOS DE AIRE DE SOBREALIMENTACION (94, 96, 98) SEPARADOS. LOS COMPARTIMENTOS DE AIRE DE SOBREALIMENTACION (84, 86) ESTRECHAMENTE ACOPLADOS ESTAN SOPORTADOS EN UNA PRIMERA ELEVACION EN EL HORNO (10) Y LOS COMPARTIMENTOS DE AIRE DE SOBREALIMENTACION (94, 96, 98) SEPARADOS ESTAN SOPORTADOS EN UNA SEGUNDA ELEVACION EN EL HORNO (10), DE TAL FORMA QUE ESTAN ESPACIADOS, PERO ALINEADOS CON LOS COMPARTIMENTOS DE AIRE DE SOBREALIMENTACION (84, 86) ESTRECHAMENTE ACOPLADOS. EL AIRE DE SOBREALIMENTACION ES SUMINISTRADO (106, 92) A LOS COMPARTIMENTOS DE AIRE DE SOBREALIMENTACION (84, 86) ESTRECHAMENTE ACOPLADOS Y A LOS COMPARTIMENTOS DE AIRE DE SOBREALIMENTACION (94, 96, 98) SEPARADOS, DE TAL FORMA QUE HAY UNA DISTRIBUCION PREDETERMINADA MUY FAVORABLE DE AIRE DE SOBREALIMENTACION ENTRE ELLOS Y DE TAL MODO QUE EL AIRE DE SOBREALIMENTACION (106) QUE SALE DE LOS COMPARTIMENTOS DE AIRE DE SOBREALIMENTACION (94, 96, 98) SEPARADOS, ESTABLECE UNA DISTRIBUCION EN "CHORRO" O EN "VENTILADOR" (124, 126, 128) DE AIRE DE SOBREALIMENTACION SOBRE EL AREA DEL PLANO DEL HORNO Y DE FORMA QUE EL AIRE DE SOBREALIMENTACION (106) SALGA DE LOS COMPARTIMENTOS DE AIRE DE SOBREALIMENTACION (94, 96, 98) SEPARADOS A VELOCIDADES SIGNIFICATIVAMENTE MAS ALTAS QUE LAS VELOCIDADES EMPLEADAS AQUI PARA ENTRAR.AN ADVANCED AIR SUPPLY AIR SYSTEM FOR NOX CONTROL IS DESCRIBED, DESIGNED FOR USE IN A COMBUSTION SYSTEM OF THE TYPE WHICH IS PARTICULARLY SUITABLE FOR USE IN FURNISHED FURNACES AND A METHOD OF OPERATION OF SUCH HORNES. AIR SUPPLY SYSTEM. THE ADVANCED SUPERCHARGING AIR SYSTEM FOR NOX CONTROL, INCLUDES MULTI-LIFTING OF SUPERCHARGING AIR COMPARTMENTS, WHICH ARE COMPOSED OF A SERIES OF CLOSELY COUPLED AIR CHARGING COMPARTMENTS (84, 86) AND A SERIES OF COMPARALLY COMPARING AIR. OVERFLOW (94, 96, 98) SEPARATED. TIGHTLY COUPLED AIR CHARGING COMPARTMENTS (84, 86) ARE SUPPORTED IN A FIRST ELEVATION IN THE OVEN (10) AND SEPARATE CHARGING AIR COMPARTMENTS (94, 96, 98) ARE SUPPORTED IN A SECOND ELEVATION IN THE OVEN 10), SUCH AS THEY ARE SPACED, BUT ALIGNED WITH THE SUPERCHARGED AIR COMPARTMENTS (84, 86) CLOSELY COUPLED. THE CHARGING AIR IS SUPPLIED (106, 92) TO THE CHARGING AIR COMPARTMENTS (84, 86) CLOSELY COUPLED AND TO THE SEPARATED CHARGING AIR COMPARTMENTS (94, 96, 98), SO THAT THERE IS A DEFAULT DISTRIBUTION FAVORABLE OF CHARGING AIR BETWEEN THEM AND SO THAT THE CHARGING AIR (106) THAT COMES OUT OF THE CHARGED CHARGING AIR COMPARTMENTS (94, 96, 98) ESTABLISHES A DISTRIBUTION IN "JET" OR "FAN" ( 124, 126, 128) OF CHARGING AIR OVER THE OVEN PLANE AREA AND SO THAT THE CHARGING AIR (106) COMES OUT OF THE CHARGING AIR COMPARTMENTS (94, 96, 98) SEPARATED AT SIGNIFICANTLY HIGHER SPEEDS THAN THE SPEEDS USED HERE TO ENTER.
