PROCESSO E DISPOSITIVO PARA PURIFICAR GASES QUENTES CONTENDO POEIRA ESPECIALMENTE GAS DE CARVAO PRODUZIDO EM REATORES DE BANHO DE ACO E BANHO DE FERRO

摘要

Coal gas produced in an iron bath reactor during the gasification of coal is first cooled down in a first cooling step to a temperature of, preferably, 300 DEG C., and is subsequently purified at this temperature in a first electrofilter, then cooled down in a second cooling step to a temperature of, preferably 50 DEG C. and, finally, purified at this temperature in a second electrofilter.
