Abstract

SOMETER A COMBUSTION FOSFORO ELEMENTAL CON AIRE SECO EN UNA CAMARA DE COMBUSTION DE ACERO INOXIDABLE USANDO EL CALOR DE REACCION PARA PRODUCIR ENERGIA. HACER LA COMBUSTION PARA FORMAR PENTOXIDO DE FOSFORO GASEOSO CALIENTE. LAS PAREDES PRESENTAN ESPACIOS HUECOS, PARA FORMAR UN SISTEMA DE REFRIGERACION, USAR COMO TRANSPORTADOR DEL CALOR EN EL SISTEMA REFRIGERACION AGUA O MEZCLA DE AGUA/VAPOR TOMANDO TEMPERATURAS DE ENTRE 100 A 370°C A UNA PRESION DE 1 A 220 BAR. RETIRAR EL VAPOR RESULTANTE DEL SISTEMA DE REFRIGERACION, Y REEMPLAZARLO POR IGUAL CANTIDAD DE AGUA FRESCA DESALINIZADAY CONDENSAR EL PENTOXIDO DE FOSFORO CALIENTE QUE SE DESPRENDE COMO VAPOR DE LA CAMARA DE COMBUSTION, A UNA TEMPERATURA DE 500 A 1.000°C Y QUE USADO, PARA PRECALENTAR EL AIRE SECO NECESARIO PARALA COMBUSTION DEL FOSFORO ELEMENTAL DE 70 A 300°C Y PARA PRECALENTAR EL AGUA FRESCA DESALINIZADA PARA EL SISTEMA DE REFRIGERACION A TEMPERATURAS DE 50 A 200°C Y POR ULTIMO CONDUCIR EL VAPOR EMERGENTE DEL SISTEMA DE RE FRIGERACION POR UN INTERCAMBIADOR DE CALOR CONTACTANDOLO CON EL PENTOXIDO DE FOSFORO GASEOSO, CON LO CUAL SE CALIENTA EL VAPOR BAJO PRESION CONSTANTE A TEMPERATURAS DE 400 A600°C OBTENIENDO VAPOR SOBRECALENTADO.
