    摘要： A method and a device (1 ) for controlling a process for burning lime containing mixture (CaCO
    3 ) and converting it to calcinated lime (CaO) in a rotary kiln (2), said rotary kiln (2) having an elongated cavity (3) surrounded by a wall (4) and a burner (5) arranged to heat the cavity (3). The method comprises collecting measurement data of the temperature in the wall (4) at a plurality of measuring points along the longitudinal axis (20) of said cavity (3), predicting the actual temperature gradient along the longitudinal axis (20) of said cavity (3) based at least on said measurement data of the temperature in the wall (4), and by means of a thermal model describing the temperature along the cavity (3) of the kiln (2), determining a desired temperature gradient along the cavity (3) based on the predicted temperature gradient along the cavity (3) and a predetermined control strategy controlling the temperature in the kiln (2) so that the area of deposition of lime on the inside of the walls (4) of the kiln (2) is controlled and the drawbacks of the lime deposition is reduced.

    摘要： The invention relates to a method and a plant for manufacturing mineralized portland cement clinker. The mineralizer may e.g. be gypsum, fluorine, or a waste product containing these or other mineralizers. By means of the method according to the invention, it will be possible to avoid some of the problems associated with the known technique, since it is possible to utilize the input of the mineralizer as a controllable parameter during the manufacture of mineralized clinker. In order to reduce or eradicate the problems in terms of build-ups and blockages in the preheater cyclones and the riser ducts between the cyclones, the mineralizer may advantageously be added after the cyclone which handles the feed to the calciner, i.e. the last cyclone in the preheater, or the lowermost preheater stage in a plant which does not incorporate a calciner. This involves that there will not be any problems in ensuring a smooth raw meal flow through the preheater, since a substantial deterioration of the flow properties of the raw meal may occur when the mineralizer is added ahead of the preheater, dependent on the type of mineralizer being selected.
