  • Patent number: 9021809
    Abstract: The invention refers to a method for operating a steam turbine power plant, and also a device for generating steam for the purpose of power generation. The method for operating a steam turbine power plant comprises at least one steam generator which is fired with a solid, granular fuel, for example with brown coal, wherein the fuel is first subject to an indirect drying in a fluidized bed drier and the fluidized bed drier is at least partially heated with steam from the water-steam cycle of the steam generator. The method is characterized in that temperature controlling in the drier is carried out in two stages in dependence upon the moisture content of the fuel, wherein first of all the temperature of the fluidized bed drier is controlled via the steam pressure of the heating steam and downstream of this controlling, a controlling of the superheating temperature of the heating steam is carried out in dependence upon the steam pressure.

  • Patent number: 8662426
    Abstract: The invention relates to a process for processing brown coal for combustion and/or gasification for the purpose of power generation, wherein the brown coal moist from the pit is firstly subjected to preliminary crushing and is subsequently comminuted. The milled coal is then fed to drying in a fluidized-bed dryer. The process is characterized in that the milling apparatus is followed by a control sieving facility, with the sieve opening being selected so that essentially 100% of the brown coal passes the sieve.

  • Patent number: 8485345
    Abstract: The invention relates to an apparatus for scattering poured goods, comprising a distributor chute (1) having a feed area (12) and having an ejection area, wherein the distributor chute (1) can be rotated about a center axis, which runs vertically in the installed position in the gravity direction of the poured goods and is mounted inclined at an angle with respect to this center axis, wherein the distributor chute (1) has a first guiding longitudinal face, which forms the front face in the rotation direction, and a second longitudinal face, which trails with respect to the rotation direction, and wherein at least the second longitudinal face forms the ejection face of the distributor chute (1). The ejection face forms an ejection edge (7), which is curved in an S-shape.

  • Publication number: 20110283555
    Abstract: The invention relates to an indirectly heated fluidized bed dryer (1) for drying moist, fine-grained bulk materials. The fluidized bed dryer (1) comprises a housing (2) with a gas-injection bottom (6) with built-in heat exchanger parts extending above the gas-injection bottom (6) and at least one discharge device, provided below the gas-injection bottom (60), for the dried bulk material. The fluidized bed dryer (1) according to the invention is distinguished in that the usable flow cross section of the housing (2) increases in the region of the built-in heat exchanger parts while the cross-sectional area of the housing remains the same over the height of the built-in heat exchanger parts in the direction of flow of the fluidizing medium. In this way, an inadmissible expansion of the stationary fluidized bed is reliably prevented.

  • Publication number: 20110283926
    Abstract: The invention relates to a method for generating process steam by burning dried lignite in a steam generator, comprising the drying of moist lignite in a fluidized bed dryer (1) with internal heat exchanger units (2) through which a heating medium flows, wherein at least some of the water is driven out of the lignite and removed from the dryer as vapors, dust is removed from the vapors in a dedusting device and the dried lignite is cooled in at least one cooler (6) arranged downstream of the fluidized bed dryer (1). The method according to the invention is distinguished by the fact that the brown coal dust occurring in the dedusting device is brought into direct contact with the dried and cooled lignite.
