The calcinator (12) is a container in which it joins below the calcinator waste gas line of the rotating kiln (16) and leads away over the calcinator waste gas line.
The combustion chamber is connected to the calcinator by means of a connection line, and additional fuel and combustion air are supplied to the calcinator.
Each amount of tertiary air flows through two or more connection opening in the calcinator.
The temperature in the upstream calcinator (3) can be lowered thus saving more energy.
The container-calcinator (12) is used to precalcinate raw meal (31) in the production of cement clinkers.
The hot CaCO3 is discharged to the calciner 42, the heat content of the CaCO3 being used to strip the CO2 from the CaO in an endothermic reaction in the calciner, with the CaO being discharged from the calciner 42 to the shift reactor 54.
The exhaust gases arising in the furnace are fed to the pre-heater after passing around the calciner and the exhaust gases from the calciner are fed to a CO2 scrubbing device.

Decomposer and Calciner, and other Major Mechanical
According to the invention, raw meal is fed into the calciner (10) of an installation for producing cement clinker, the raw meal being delivered pneumatically to the calciner (10) by means of a gas stream.
The gas stream is introduced into the calciner (10) in an essentially horizontal manner.
The remaining photoresist can then be removed in a conventional high-temperature asher.
According to the invention, the discharge shaft (7) has a substantially horizontal arrangement (9) via which the raw meal (11) flows into the calciner transverse to the direction in which the gas of the calciner (3) streams.
According to the invention, raw meal is fed into the calciner (10) of an installation for producing cement clinker, the raw meal being delivered pneumatically to the calciner (10) by means of a gas stream.
The gas stream is conducted with the least possible flow resistance in the calciner (10).
The gas stream is conducted with the least possible flow resistance in the calciner (10).
The gas stream is introduced into the calciner (10) in an essentially horizontal manner.
The refinery unit effluent gas may be the offgas from a rotary kiln calciner.
The second chemical process loop 52 has a water-gas shift reactor 54 and a calciner 42.
A tertiary air line or bifurcated tertiary air line (12) opens into the calciner and a raw meal feed line (15) opens into the tertiary air line (12) at a short distance upstream of the calciner or bifurcation.
