    摘要: An object of the present invention is to separate CO2 gas generated in a cement-manufacturing facility in a high concentration and recover the CO2 gas. The present invention includes: feeding a cement material before calcination and a heat medium which has a particle diameter larger than that of the cement material and has been heated to the calcination temperature or higher in a medium-heating furnace (14), to a mixing calciner (12); and recovering the CO2 gas generated by the calcination of the cement material. The heat medium circulates between the medium-heating furnace and the mixing calciner. Another aspect of the present invention includes: feeding a cement material before calcination to a regenerative calciner (112) which has been heated to the calcination temperature or higher and has stored heat therein; and recovering the CO2 gas generated by the calcination of the cement material.

    摘要: A method and an apparatus for manufacturing of cement includes cement raw meal being preheated in a preheater, calcined in a calciner by contact with hot gases which are introduced into the calciner via a gas inlet and being diverted from the calciner via a gas outlet, and where calcined cement raw meal is diverted from the calciner, burned into cement clinker in a kiln and subsequently cooled in a clinker cooler. At least a portion of the calcined cement raw meal diverted from the calciner is heated further in a separate system to a temperature which exceeds the calcination temperature and is subsequently recirculated to the calciner. That at least a portion of the gases which are diverted via the gas outlet of the calciner is removed from the plant with a view to storage underground or other additional treatment.

    摘要: Described is a method as well as a plant for preheating particulate or pulverulent material such as cement raw meal or similar material in a cyclone preheater (1), comprising at least two cyclone stages, each comprising a riser duct (2a, 2b, 2c, 2d) and a cyclone (1a, 1b, 1c, 1d). The method is peculiar in that a portion of the material which is fed to at least one cyclone stage is introduced to the first part of the riser duct, viewed in the direction of travel of the exhaust gases, and is heated from a temperature of maximum 450° C. to a temperature of at least 550° C., and in that the remaining material which is fed to the same cyclone stage is introduced into the last part of the said riser duct. As a result, there will be a reduction in the amount of SO2 which is discharged from the cement plant preheater as emission, without a simultaneous increase in energy consumption.

    摘要: For a decrease of NO.sub.x content in the exhaust gases from cement-burning kilns by an addition of ammonia and/or ammonia-containing substances to hot exhaust gases, the exhaust gases are desulfurized at a temperature from 50.degree. to 100.degree. C. in a dry or semidry process by a mixture of raw cement powder and calcium hydroxide, and the mixed solids which have been removed the exhaust gas in a dry state in the desulfurizing stage are returned to the exhaust gas stream when it is at a temperature from 850.degree. to 1,000.degree. C.
