Abstract
An apparatus for the production of a mineral melt burns combustible material in the presence of inorganic particulate material to form a melt. The apparatus has a circulating combustion chamber having at least two inlets which receive fuel, pre-heated mineral material, and combustion gas. A heat exchange system for pre-heating the mineral material has a pre-heater cyclone, a conduit running from the circulating combustion chamber to the first pre-heater cyclone for transporting exhaust gases, a material inlet for injecting the material into the conduit, and a bottom cyclone outlet for feeding pre-heated mineral material to the combustion chamber. The outlet of the pre-heater cyclone stabilizes and splits the mineral material flow into two material flows for feeding combustion chamber inlets.
