Abstract

UN PROCESO Y UNA PLANTA PARA LIMPIAR EL GAS DEL HORNO. SE USAN UNO O MÁS SENSORES PARA CONTROLAR CONTINUAMENTE UNO O MÁS PARÁMETROS INDICATIVOS DE UN PICO DE TEMPERATURA ESPERADO EN EL FLUJO DE GAS DE ALTO HORNO. EL FLUJO DE GAS PASA A TRAVÉS DE UNA TORRE DE ACONDICIONAMIENTO. EN CASO DE QUE EL PARÁMETRO MEDIDO EXCEDA UN VALOR LÍMITE PREDEFINIDO, UN REFRIGERANTE, TAL COMO AGUA, SE PULVERIZA EN EL FLUJO DE GAS DEL ALTO HORNO EN LA TORRE DE ACONDICIONAMIENTO. POSTERIORMENTE, EL FLUJO DE GAS DE ALTO HORNO PASA POR UNA O MÁS ESTACIONES DE FILTRACIÓN.
