Le procédé de réduction de la consommation calorifique des fours de cimenterie en voie humide par réduction de la teneur en eau du cru consiste essentiellement à introduire dans le four une partie des matières premières entrant dans la composition du cru, délayées par adjonction d'eau sous forme de pâte, et l'autre partie des matières premières, à leur humidité naturelle, sous forme de granules. Le degré d'humidité pour former les granules est amené à la valeur voulue de 14 à 18 % par l'adjonction dans le granulateur, aux matières premières à leur humidité naturelle, soit de poussières de récupération lorsque la teneur en humidité des matières premières est trop élevée, ce qui sera le cas le plus fréquent, soit de pâte lorsque la teneur en humidité des matières premières est trop faible.

In a method for treating exhaust gas in an exhaust gas treatment device (8) of a system, the exhaust gas is removed from a processing device for mechanically and/or thermally processing an inorganic material of the system, and the material to be fed to the processing device is heated by the exhaust gas as a result of heat exchange. The disclosed method is characterized in that the temperature of the exhaust gas entering the exhaust gas treatment device (8) is adjusted by having the exhaust gas adequately exchange heat with the material.

A method for manufacturing a high-strength cement cured product constituted by: mixing and kneading cement with at least water and water-reducing agent; putting the cement kneaded mixture (5) into a vacuum device and removing air and dehydrating by vacuum evacuation; forming an impermeable coating layer (7) on the surface of the cement kneaded mixture (5) contained in a container inside the vacuum device (1) and then exposing the cement kneaded mixture (5) to atmospheric pressure; and then curing the cement kneaded mixture (5). This enables it to be hardened while having a reduced air amount. Thereby, a high-strength cement cured product having high compressive strength can be obtained.

The invention relates to a method for producing marl slags and marl slag cements or mixed constituents for mixed cements made of marl with a basicity CaO/SiO2 of < 2.0. According to the invention, the argillaceous marl or a mixture consisting of marl and clay with a basicity of < 2.0 is, in a first method step, dried, preheated and calcined. In a second step, the resulting product is subsequently melted in a separate smelting furnace at temperatures higher than those used in the first method step, and the melt is then granulated.
118	Method of producing cement clinker and electricity	EP99810828.6	1999-09-16	EP1092692A1	2001-04-18	Srinivasachar, Srivats; Toqan, Majed; Kang, Shin G.; Burdis, Vassilios
In a method of producing cement clinker and electricity, cement raw mix and hydrocarbon are fed in a circulating fluidized bed boiler (1). Therein cement raw mix is calcined and steam is produced. Gas and solids out of the fluidized bed enter a cyclone (8), the solids being separated therein and returned to the bed. Part of those solids are first cooled down in a solids heat exchanger (9) producing steam. Fly ash consisting predominantly of lime and gas escaping the cyclone are passed through a heat exchanger (28, 33) and a filter (37). Hot bed material is discharged from the circulating fluidized bed and is ground with additives, then blended with lime being separated in the filter (37), then supplied to a rotary kiln (16), wherein the solids are clinkered. The produced steam is fed to a steam turbine island (42).
