    Abstract: In a method for the preheating of cement raw meal for the production of cement-clinker, in which the cement raw meal is conveyed towards the feed side of a cement clinker kiln (1) in at least one heat exchanger-line in counter flow to hot gases, the hot gases are drawn off via at least a first heat exchanger (2) connected with the feed end of the cement clinker kiln (1) and via heat exchanger-lines (3,4) following this first heat exchanger (2) and being parallel to each other. The device for carrying out said method is characterized in that heat exchanger-lines (3,4) arranged in parallel to each other are connected to at least a first heat exchanger (2) joined to the feed end of the cement clinker kiln.

    Abstract: In a process for utilizing organic waste materials, in particular cellulose-containing, moist, organic waste materials, in a clinker production process in which the waste materials are introduced as fuel and burnt in the clinker production process, the waste materials are brought into contact with the hot exhaust gases of the clinker production process and dried in a drying step flowing in parallel therewith before they are introduced into the clinker production process. The drying step is carried out in a drying reactor in which the moist waste materials are passed together with the hot exhaust gases through a series of concentrically arranged tubes, with multiple changes in flow direction about 180°, and the temperature of the hot exhaust gases is set to a maximum value of 400° C. by mixing in of ambient air and/or air from the clinker production process before the drying step.

    Abstract: In a method for introducing waste substances and/or alternative fuels into a clinker production process, the raw materials, in the form of slurries or suspensions, are subjected to mechanical deagglomeration as a pumpable mass. The pumpable mass is ejected into risers, precalciners and/or the rotary tubular kiln. The device for carrying out the method is characterized by a tubular housing (1) including a rotor (2) mounted to be rotational substantially concentrically with the tube axis and driveable for rotation with blades (3) sweeping over the space between the rotor shaft and the housing wall, wherein a plurality of ducts and openings (6, 7, 11, 14) are connected to the shell of the tubular housing (1), and at least one duct (6) is arranged with the slurry supply and at least one duct is offset in the peripheral direction.

    Abstract: A method for reducing the chromium content from a metallurgical slag, in which the slag is charged onto an iron bath in the liquid state and the reduction of Cr is effected by the iron bath having a C content of 2 to 4% by weight, wherein a) the Cr-containing slag having a Cr content of 2 to 20% by weight is charged onto an iron bath having a C content of below 1% by weight, whereupon b) the carbon content of the iron bath is raised to about 2 to 4% by weight by the addition of carbon carriers at the simultaneous supply of energy, c) the liquid slag having a Cr content of about 0.1% by weight is tapped after the reduction of Cr, d) a cooling agent, preferably scrap, is added to the iron melt and the C content of the melt is lowered to below 1% by weight, and e) a portion of the Cr-containing melt is tapped in the liquid state, while the remaining portion is left in the converter in the liquid state for the treatment of the subsequent melt.
