Beschreibung
Zusammenfassung:	This invention relates to the thermal treatment of lump or agglomerated material in a firing machine (1 ) with a travelling grate (2) on which the material is conveyed through the firing machine (1 ), a firing chamber (4) for generating the temperatures required for the thermal treatment, a cooling zone (5) in which cooling gases are passed through the thermally treated material, and a recuperation tube (7) through which the heated cooling gases are recirculated to the firing chamber (4). In the ceiling (8) of the firing chamber (4) a plurality of openings (9) is provided, through which the heated cooling gases from the recuperation tube (7) can enter into the firing chamber (4).
