  • Patent number: 7021013
    Abstract: A compensator (18) is provided for compensating thermal expansions of ducts or pipelines (10) for carrying flows of hot media, especially ducts that are lined with fire-proof material. The compensator (18) is easy to maintain and is relatively simple in its design. This compensator (18) permits inspection of the operability of the expansion gap (19) between adjacent sections of the pipeline (10) and its elastic temperature-resistant jointing material (20) from the outside of the pipeline. The expansion gap (19) in the flame-proof lining is arranged in a cross section plane of the pipeline that is adjacent to but below the cross section plane of the corrugated pipe compensator (18) attached to the steel sheet jackets (15) of adjacent sections of pipeline (10).

  • Patent number: 6837913
    Abstract: A hot gas cyclone separator is provided with a segmented dip tube whose smooth sheet metal dip-tube segments have tops which are securely fastened to a cap of the separator in hook like manner by U-shaped angle rails. The adjacent lower ends of the dip-tube segments may also be interconnected by angle rails having U-shaped profiles which serve to protect the lower end of the dip tube from excessive wear caused by the impinging hot gas/solids suspension.

  • Patent number: 6517597
    Abstract: A heat-resistant and wear-resistant insertion element or segment of a segmented dip tube suitable for use in a refractory-lined cyclone of a cement clinker production line. The insertion element, is capable of being fabricated and installed with a length greater than 120 cm, and is distinguished by a long service life. The insertion element may be a composite structure made of a metallic carcass or sheet (10) and a metallic mesh with webs (11) forming lattice-shaped openings which are filled with a heat-resistant ceramic composition (12).

  • Patent number: 6468075
    Abstract: Cement clinker production apparatus having a precalcination stage connected upstream of a rotary kiln, in which precalcination stage a CO-containing reduction zone in the rotary kiln off-gas duct is employed for the purpose of reducing the pollutant NOx. In order to make certain that the quantitative ratio of O2 in the rotary kiln off-gas to fuel admitted by a deNOx burner, and thus control the effectiveness of NOx reduction, a pivoting throttle valve (33) is positioned in the precalcination stage to control the quantity of rotary kiln off-gas and thus the O2 content in the kiln off-gas. The throttle valve (33) is positioned in the rotary kiln off-gas duct (15) above the deNOx burner (19), above the raw meal inlet (13), and before the confluence of the tertiary air substream with the rotary kiln off gas.

  • Patent number: 6214075
    Abstract: In order to create a cyclone separator with segmented immersion pipe for cement clinker manufacturing system with cyclone suspension type heat exchanger system, whereby the releasable immersion pipe segment fastening is dependable and is distinguished by a long service life, it is inventively proposed to secure the immersion pipe segments at their upper end with releasable screw bolts, whereby the screw bolts are arranged in spacer sleeves distributed around the immersion pipe circumference that respectively comprise at least one window-like opening at the outside for the access of ambient air as coolant for the immersion pipe segment fastening.

  • Patent number: 6000937
    Abstract: A cement plant for the production of cement clinker from cement raw meal has a flat plate shaped control element for distributing and/or transporting-feeding a stream of hot flour-like material which is subjected to severe thermochemical and abrasive ware. the service life of the control element is greatly increased by constructing it as a hollow body (19, 22) through which coolant flows from at least one inlet opening to at least one discharge opening.

  • Patent number: 5682200
    Abstract: A telecine scanner having a capstan roll (3) continuously advancing the film through a picture scanning station, includes a capstan motor (2) controlled by a phase signal derived from a tachodisc (7) of a sprocket (8) driven by the film (1). To improve vertical picture steadiness, this phase signal is derived from a higher-frequency pulse signal after the capstan roll (3) has run up to speed.

  • Patent number: 4505051
    Abstract: A cyclone heat exchanger particularly adapted for direct heat exchange between a granular product and hot exhaust gases from a kiln used in the production of cement, the heat exchanger comprising a housing, a gas feed pipe introducing hot gases tangentially of the housing, a cover extending across the top of the housing, a discharge at the base of the housing for discharging product therefrom. The improvement consists of an immersion pipe extending through the cover and into the housing, the immersion pipe consisting of a plurality of segments extending in the longitudinal direction of the immersion pipe. Holding devices are provided for releasably holding segments in the cover.
