Abstract

Настоящее изобретение относится к способу регулирования обжиговой печи при обжиге в псевдоожиженном слое. Часть решетки обжиговой печи отделена с образованием отдельной секции переливной решетки, где можно регулировать сопла и количество продуваемого через них обжигового газа независимо от основной решетки. В предпочтительном варианте располагают отдельно регулируемую решетку в той секции печи, где находится переливное отверстие.Международная заявка была опубликована вместе с отчетом о международном поиске.
