Abstract
"DISPOSIçãO E MéTODO PARA AQUECIMENTO DE GáS EM UM DUTO DE GáS, EM CONEXãO COM UM PROCESSO DE SINTERIZAçãO CONTINUAMENTE OPERADO". A presente invenção se refere a uma disposição e método para aquecimento de gases em um duto de circulação de gás, em conexão com um processo de sinterização continuamente operado. No forno de sinterização, gás quente é alimentado a partir de cima da esteira, a fim de sinterizar o material localizado sobre a esteira e uma parte do duto de circulação de gás é formada como um anel queimador de uma zona de queima, onde o gás é aquecido. O anel queimador compreende pelo menos uma unidade queimadora, dirigida na direção interna, a partir da periferia do duto de circulação de gás.
