Abstract

método para controlar a aspiração de fumos de escape e dispositivo para controlar um dispositivo de extração de fumos de escape. método para controlar a aspiração de fumos de escape durante um processo de fabricação de aço em um caço de fabricação de aço, em que o método compreende as seguintes etapas: - capturar pelo menos uma imagem de chamas escapando do topo do caço de fabricação de aço, - calcular pelo menos um valor representativo do tamanho e/ou da intensidade da chama com base na pelo menos uma imagem de chama capturada, - medir uma pressão representativa da pressão dos fumos aspirados, - controlar a aspiração de fumos com base no referido valor representativo da chama e na pressão medida.method for controlling the suction of exhaust fumes and device for controlling an exhaust fume extraction device. method for controlling the aspiration of exhaust fumes during a steelmaking process into a steelmaking shaft, wherein the method comprises the following steps: - capturing at least one image of flames escaping from the top of the steelmaking shaft , - calculate at least one value representative of the size and/or intensity of the flame based on at least one captured flame image, - measure a pressure representative of the pressure of the aspirated fumes, - control the fume aspiration based on said value representative of the flame and measured pressure.
