Abstract

trata-se de um processo e um dispositivo para tratar um fluxo de gás de forno com uma pressão de mais do que 0,1 mpa (1 bar) que flui através de um canal (3). um agente em pó (2), tal como um pó que compreende reagentes alcalinos, tal como cal, e/ou absorventes, tal como carvão ativado, é injetado sob uma sobrepressão no fluxo de gás de forno através de um injetor (6) que está posicionado centralmente dentro do canal. o agente em pó pode ser fluidizado. a pressão para injetar o pó pode ser ajustada controlando-se o volume do gás de fluidização ventilado através da saída de ventilação (24).
