This patent describes an apparatus for retorting oil shale particles of variable size, including fines, comprising: a substantially vertical cascading burner having a pair of opposing walls; vertically spaced baffles extending from the opposing walls of the burner inwardly and downwardly into the burner in an overlapping relationship, successive baffles extending alternately from opposing walls of the burner the baffles. The baffles comprise a first segment and a second segment connected to and above the first segment and having a slope greater than the first segment. The first segment has a slope, measured from the horizontal, in the range of about 24/sup 0/ -60/sup 0/; a substantially vertical cascading mixer below the burner, the burner being mounted to the mixer and communicating therewith through an opening therebetween, the mixer having a pair of opposing walls; vertically spaced baffles extending from the opposing walls of the mixer inwardly and downwardly into the mixer in an overlapping relationship, successive baffles extending alternately from opposing walls of the mixer; raw shale input means mounted to the top of the mixer adjacent to the burner and communicating with the mixer through an opening therebetween; a substantially vertical moving packed bed pyrolyzer below the mixer, the mixer being mounted to and opening into the pyrolyzer; spent shale removal means connected at the bottom of the pyrolyzer and communicating with the pyrolyzer through an opening therebetween; and product removal means operatively connected to the pyrolyzer.
