    摘要： The invention relates to a method for producing aerated concrete on the basis of a mixture that comprises quartziferous sand and/or quartziferous stone dust, a quicklime-containing binder, water and a pore forming material and optionally cement and/or anhydrite. The invention is characterized in that the quicklime is substantially completely slaked with water before the pore forming material is added to the mixture, thereby making it possible for the pore formation to be carried out in a mixture that has a constant temperature and a constantly high consistency. The inventive method allows for easily reproducible aeration results and gives an aerated concrete with a very low dry bulk density and high compression strength.

    摘要： Methods and a slaker for removal of heavy grit during batchwise slaking of burnt lime in a slaker (2) for the production of lime slurry with a high degree of fineness and prolonged sedimentation time are described, where the following processing steps are carried out during the slaking process: a)—reduction of the stirring of the slaker (2) from a normal stirring speed to a lower stirring speed, b)—opening of an upper inlet valve (60) in a collector (70) mounted in the lower part (54) of the slaker (2) to lead sinking grit in the slurry batch to the collector (70), whereupon the upper inlet valve (60) is closed after a given time period, c)—increase the stirring in the slaker (2) back to the normal stirring speed, d)—after a given time period with normal stirring speed, a regulating valve (22) in the lower part (54) of the slaker (2) is opened for emptying of a batch of slurry to an external storage tank (3), and e)—when said regulating valve (22) is opened for emptying of a batch of slurry, a lower outlet valve (62) in the collector is optionally opened for emptying of collected grit.

    摘要： A lime hydrator (20) integrated into a flue gas desulfurization system (18) or other industrial system is provided that provides an in-situ variable rate of cured hydrated lime production for a variable supply rate of the in-situ produced cured hydrated lime for use within a flue gas stream as a moistened hydrated lime for a reduction of acid gas present in a flue gas stream. Also provided is a method of using a lime hydrator (20) integrated into a flue gas desulfurization system (18) or other industrial system to provide in-situ a variable production rate of cured hydrated lime for a variable supply rate of the in-situ produced cured hydrated lime for use within a flue gas stream as a moistened hydrated lime for a reduction of acid gas present in a flue gas stream.
