Abstract

METODO PARA CONTROLAR LA COMBUSTION EN UN PROCESO CALEFACTOR. COMPRENDE: A) CALCULAR UN FLUJO CALORIFICO REQUERIDO PARA PRODUCIR UNA TEMPERATURA DESEADA DEL PRODUCTO FINAL; B) CONTROLAR LA POSICION DEL REGULADOR DE TIRO EN EL CONDUCTO DE HUMOS DEL CALEFACTOR COMO UNA FUNCION DEL FLUJO CALORIFICO COMPUTADO; C) CALCULAR EL FLUJO CALORIFICO TOTAL DEL COMBUSTIBLE EN CALEFACTOR; D) COMPARAR EL FLUJO CALORIFICO CALCULADO CON EL FLUJO CALORIFICO; Y E) REGULAR EL FLUJO DE COMBUSTIBLE EN EL CALEFACTOR COMO UNA FUNCION DE LA DIFERENCIA ENTRE EL FLUJO CALORIFICO CALCULADO Y EL FLUJO CALORIFICO REQUERIDO. BASANDO LA TEMPERATURA DEL PRODUCTO FINAL EN LA ENTALPIA DEL MATERIAL DE ALIMENTACION Y EN LA ENTALPIA DESEADA DEL PRODUCTO FINAL.
