Abstract

Настоящее изобретение относится к установке для термической обработки твердых материалов, содержащих оксид железа, на которой мелкозернистые твердые материалы нагреваются до температуры от 700 до 1150°С в реакторе с псевдоожиженным слоем (8). С целью улучшения использования энергии предлагается вводить первый газ или газовую смесь снизу через по меньшей мере одну газоподводящую трубу (9) в область смесительного пространства (15) реактора (8), причем газоподводящая труба (9), по крайней мере, частично окружена стационарным кольцевым псевдоожиженным слоем (12), который псевдоожижается подаваемым псевдоожижающим газом. Объемные скорости первого газа или газовой смеси и псевдоожижающего газа для кольцевого псевдоожиженного слоя регулируют таким образом, чтобы число Фруда для частиц в газоподводящей трубе (9) было в пределах от 1 до 100, в кольцевом псевдоожиженном слое (12) от 0,02 до 2 и в смесительном пространстве (15) от 0,3 до 30.
