摘要： A process and apparatus for manufacturing cement clinker in which pellets of raw material containing the necessary components for manufacturing the clinker are introduced into an apparatus where the pellets flow under gravity, successively through a preheating zone, a clinkering zone using a fluidized bed and a cooling zone. The pellets contain an amount of comminuted carbon determined so that its combustion produces an amount of heat within each pellet sufficient to carry out decarbonation of the material, taking into account the heat introduced by the hot gases passing upwardly through the apparatus. Decarbonation is completed at the base of the preheating zone and the pellets enter the clinkering zone at a temperature which is close to the clinkering temperature. Additional heat is supplied through burners within the clinkering zone.

摘要： A process for the firing and sintering of granular material in a gas or oil heated shaft furnace is disclosed in which the material, fed from the top of the furnace passes downwards successively through an entry zone, a preheating zone, a firing zone in which burners are disposed around the furnace wall, and a cooling zone, and in which the feeding of the material at the top of the furnace is so effected that a central depression is maintained in the upper surface of the material in the entry zone, said surface sloping downwardly from the periphery of the entry zone into the central depression, so that segregation of the material occurs automatically, the coarser pieces of material rolling into the central depression, whereby a column of the coarser material is maintained along the vertical axis of the furnace. The feeding of the material at the top of the furnace is effected by means of a charging bell over which the material to be fed to the furnace is discharged, the material being guided by the charging bell to the periphery of the entry zone and then rolling into the central depression below the charging bell.

摘要： AN APPARATUS FOR AND METHOD OF MANUFACTURING WHITE PORTLAND CEMENT CLINKER ARE DISCLOSED. THE APPARATUS HAS A REACTOR PROVIDED WITH A REACTOR BED ADAPTED TO RECEIVE AND PROCESS WHITE PORTLAND CEMENT CLINKER RAW MATERIAL. THE REACTOR HAS A HEATING AND DRYING ZONE FOR REMOVING THE WATER FROM THE RAW MATERIAL, A CALCINING ADJACENT THE HEATING AND DRYING ZONE FOR CALCINING THE CALCAREOUS PORTION OF RAW MATERIAL, A REACTION ZONE ADJACENT THE CALCINING ZONE FOR CLINKERING THE RAW MATERIAL, A GAS DISTRIBUTION ZONE ADJACENT THE REACTION ZONE FOR RECEIVING A HEATING AND REDUCING FLUID HAVING A PRESSURE SUFFICIENT TO TRAVERSE THE REACTION ZONE, THE CALCINING ZONE AND THE HEATING AND DRYING ZONE WITH A RESIDUAL REMAINING PRESSURE, AND A GAS SEAL ZONE ADJACENT THE GAS DISTRIBUTION ZONE. A DIVIDER IN THE GAS SEAL ZONE SPLIT THE FLOW OF THE SINTERED RAW MATERIAL INTO TWO CHANNELS. EACH CHANNEL HAS A CONSTRICTED PASSAGE IN THE DIRECTION OF THE FLOW OF THE SINTERED RAW MATERIAL TO PRODUCE A PRESSURE DROP THROUGH THE GAS SEAL ZONE GREATER THAN THE PRESSURE IN THE HEATING AND REDUCING FLUID. A COOLING ZONE OF THE REACTOR ADJACENT THE GAS SEALING ZONE COOLS THE SINTERED RAW MATERIAL. A COOLING PLENUM IN THE COOLING ZONE IS CONNECTED TO THE HEATING AND DRYING ZONE AND HAS A FIRST LOUVER WHICH DEFINES WITH AN EXIT LOUVER THE COOLING ZONE, THUS RETAINING THE SINTERED RAW MATERIAL IN THE COOLING ZONE WHILE EMITTING THE HEATING AND REDUCING FLUID FROM SUCH COOLING ZONE. A DISCHARGE MEANS IN DISCHARGE ZONE OF THE REACTOR DISCHARGES THE SINTERED MATERIAL WHILE SEALING THE DISCHARGE ZONE FROM THE ATMOSPHERE. THE METHOD INCLUDES THE STEPS OF: (A) RECEIVING THE RAW MATERIAL IN THE REACTOR BED OF THE REACTOR, (B) PASSING THE RAW MATERIAL THROUGH A HEATING AND DRYING ZONE TO REMOVE THE WATER FROM THE RAW MATERIAL, (C) PASSING THE DRIED RAW MATERIAL THROUGH A CALCINING ZONE ADJACENT THE HEATING AND DRYING ZONE TO CALCINE THE CALCAREOUS PORTION OF THE RAW MATERIAL, (D) PASSING THE REACTED RAW MATERIAL THROUGH A GAS DISTRIBUTION ZONE ADJACENT THE REACTION ZONE TO RECEIVE A HEATING AND REDUCING FLUID PRODUCED FROM A FLUID FUEL BURNED IN A DEFICIENCY OF OXYGEN-BEARING GAS AND HAVING A PRESSURE SUFFICIENT TO TRAVERSE THE REACTION ZONE, THE CALCINING ZONE AND THE HEATING AND DRYING ZONE WITH A RESIDUAL REMAINING PRESSURE, (E) PASSING THE RAW MATERIAL THROUGH A GAS SEALING ZONE ADJACENT THE GAS DISTRIBUTION ZONE, (F) SPLITTING THE FLOW OF THE SINTERED RAW MATERIAL IN THE GAS SEAL ZONE INTO TWO CHANNELS, EACH CHANNEL HAVING A CONSTRICTED PASSAGE IN THE DIRECTION OF THE FLOW OF THE RAW MATERIAL TO PRODUCE A PRESSURE DROP THROUGH SUCH GAS SEAL ZONE GREATER THAN THE ORIGINAL PRESSURE IN SUCH HEATING AND REDUCING FLUID, (G) PASSING THE SINTERED RAW MATERIAL THROUGH A COOLING ZONE ADJACENT THE GAS SEAL ZONE TO COOL THE SINTERED RAW MATERIAL UNDER REDUCING CONDITIONS, (H) RECEIVING THE HEATING AND REDUCING FLUID AT THE RESIDUAL REMAINING PRESSURE IN A COOLING PLENUM IN THE COOLING ZONE, (I) RETAINING THE RAW MATERIAL IN THE COOLING ZONE WHILE EMITTING THE HEATING AND REDUCING FLUID FROM THE COOLING PLENUM INTO THE COOLING ZONE, (J) RETAINING THE RAW MATERIAL IN THE COOLING ZONE WHILE EMITTING THE HEATING AND REDUCING FLUID FROM THE COOLING ZONE THROUGH AN EXIT LOUVER, (K) PASSING THE SINTERED RAW MATERIAL THROUGH A DISCHARGE ZONE ADJACENT THE COOLING ZONE, AND (L) DISCHARGING THE RAW MATERIAL WHILE SEALING THE DISCHARGE ZONE FROM THE ATMOSPHERE.
