Abstract

"MéTODO PARA QUEIMAR UMA MISTURA DE MATERIAL MINERAL". A fim de ser capaz de queimar uniformemente no fluxo de gás combustível uma mistura de material mineral de tamanhos de grão diferentes num forno com chaminé com uma chaminé alongada ou rectangular de secção transversal, a coluna de material de base (9') é produzida alterando periodicamente a direcção da separação direccionada que ocorre durante o carregamento e.g. por meio de uma trajectória (25) ou de uma calha, de modo que a distribuição direccionada do tamanho de grão se altere em camadas na coluna de material de base (9<39>). A direcção é alterada pela articulação de uma calha (24) na direcção oposta.
