    摘要: A stream of raw material is passed through a preheater to a furnace and a stream of exhaust gases from the furnace is passed through the preheater to preheat the raw material. Dust is electrostatically precipitated from the exhaust gases leaving the preheater, and the temperature of such exhaust gases is controllably raised to improve the efficiency of the dust removal by bypassing a controlled proportion of at least one of said streams around at least a portion of the preheater.

    摘要: A chamber which forms a material inlet and an exhaust gas outlet at one end of a rotary kiln has an inclined bottom arranged to cause preheated fine material deposited thereon to slide by gravity into the end of the rotary kiln. A dense stream of fine granular material is deposited on such inclined surface, and fuel in finely divided form is introduced into the dense stream of material flowing down the inclined surface to cause the fuel to become intimately mixed with the material. Gas is discharged from the kiln in contact with the stream of material as such a velocity as to entrain a substantial proportion of such stream, the temperature and composition of the gas being such as to cause combustion of the fuel mixed with the entrained material.

    摘要: The heat treatment of fine-grained material such as ground raw cement comprises preheating the material, mixing the preheated material with fuel under conditions incapable of supporting combustion, subsequently combusting the fuel in intimate relation with the material, and finally firing the material in a rotary tube furnace.

    摘要: Processes and apparatus for the heat treatment of fine-grained material, particularly for the production of cement, wherein the material is preheated in a preheater, further heated in a precalcination zone using additional fuel, calcined to completion in a rotary kiln, and cooled in a cooler, the preheated material being introduced into a cooling air stream run off from the cooler and the resulting mixture of gas and solids being introduced from the side into a gas pipe which connects the rotary kiln to the preheater and through which the kiln exhaust gases flow in the upward direction.

    摘要: Fine grained material such as raw cement meal is preheated in a preheater and discharged from the latter into a rotary kiln for calcining and through which hot exhaust gases pass in counterflow to the material. Immediately after introduction of the material to the kiln fuel is sprayed onto the surface of the material and is covered either by additional material from the preheater or by circulation of the material already in the kiln, due to rotation of the kiln at an elevated speed. The fuel is combusted virtually entirely within the kiln and substantially directly at the material without previous gasification of the fuel.
