Abstract (en)
[origin: US4840561A] The invention relates to apparatus for the heat treatment of fine-grained material with a rotary drum furnace, a preheater and a combustion chamber for precalcination, in which the cover of the combustion chamber has a central recess which serves for spin stabilization and has the fuel supply provided in its base. Such a combustion chamber is distinguished by improved combustion conditions, particularly an improved mode of combustion.
