  • Refining lignite in the sense of the present invention means at least drying and grinding the lignite for the purpose of producing a marketable product that can be used outside the power plant process.
  • Refinement can include at least the production of a dried, powdery or granular end product, which is subjected to thermal recycling in a power plant or a further refinement for the enrichment of carbon in the end product.
  • a further refinement step for example, the production of hearth furnace coke, liquefaction, gasification or the production of fuel pellets can be provided.
  • Mine-moist raw lignite in the sense of the present invention is to be understood as the mined and not prepared raw lignite, which can have a moisture content between 40% by weight and 60% by weight, depending on the conditions of the deposit or storage time before refining.
  • the raw lignite When lignite is converted into electricity, the raw lignite is usually fed to a beater mill which has been rendered inert with flue gas. The raw lignite is crushed in the mill. The flue gas is used to dry the moist coal and transports the lignite dust generated as a carrier gas through a classifier to the boiler's burner.
  • the refining of lignite requires a possibly multi-stage grinding and separate drying of the raw lignite in a separate drying unit.
  • Tube dryers, fluidized bed dryers or roller bowl mills are used as drying units.
  • multi-stage pre-comminution and / or grinding of the raw lignite is usually provided.
  • fluidized bed dryers can only be operated with a relatively narrow feed belt, since otherwise the fluidized bed would collapse.
  • the operation of tube dryers is energy-intensive. These are usually operated with steam from a coupled power plant process.
  • the specific steam volume required to operate a tube dryer is approximately 1.35 kg steam per kilogram of raw coal.

  • the raw lignite itself is used as grinding media within a correspondingly configured unit.
  • the steam jet entering the regrind bed comprising the pre-broken or pre-comminuted raw lignite as regrind, interacts with the fluid bed surrounding it in such a way that an exchange of impulses takes place between the steam jet and the regrind, which leads to comminution of the regrind and at the same time to drying it in the Steam atmosphere leads.
  • the steam jet, together with part of the regrind is accelerated into the fluidized regrind bed and this is done in such a way that particle collisions within the regrind bed occur.
  • the individual lignite particles are exposed to an impact, which leads to comminution without the use of grinding media or impact internals within the unit concerned.
  • several Steam jets introduced into the regrind bed in opposite directions, for example in such a way that steam jets meet.
  • the comminution and drying can be carried out in at least one, preferably in a plurality of hydraulic jet mills connected in parallel, preferably in fluid bed counter-jet mills.

  • Such comminution is particularly advantageous if the upgrading process is coupled to a power plant process, in which case appropriately conditioned steam from the power plant process or steam generation process is available.
  • a part of the dry brown coal is thermally utilized in the power plant process, the rest of the power plant process preferably being operated with raw brown coal as fuel.

  • both water and volatile constituents of the raw brown coal are expelled as fuel gas from the raw brown coal during the drying, the fuel gas being stored and / or separately thermally utilized.
  • volatile constituents or volatile gaseous constituents in the sense of the present invention are to be understood exclusively as hydrocarbons, but not the roughly capillary bound water of the raw lignite.
  • a further process variant according to the invention provides that the grinding and drying take place in two stages, the grinding and drying taking place in one stage by means of at least one steam jet at a first low temperature and in a second stage using at least one steam jet at a second higher temperature,
  • the low temperature may be on the order of 200 ° C
  • the higher temperature may be on the order of 300 ° C.
  • the ground material When a steam jet is introduced at a temperature of approximately 200 ° C. and a pressure of approximately 5 bar, the ground material is only finely comminuted and dried, the dried ground material then preferably having a residual water content of approximately 2% by weight to 4% by weight. can have. In this case, the product obtained still contains significant amounts of volatile gaseous components.
  • steam can be supplied at a temperature of approximately 300 ° C., which results in the volatile gaseous components being expelled from the raw lignite.
  • volatile constituents can, for example, be stored separately and / or sent for thermal recycling.
  • the steam generator is supplied with a portion of the dry lignite from which the volatile constituents have already been driven off.
  • the volatile constituents can be compressed as fuel gas and fed to a natural gas network or a natural gas storage facility.
  • steam with a relatively high energy content is required, which is no longer available to generate electricity at the turbine power plant.
  • the partial stream of dry lignite not supplied for thermal utilization can be coked, for example, in a further upgrading step to hearth furnace coke if and to the extent that this dry lignite still contains gaseous volatile constituents. If the volatile components are completely expelled in the second stage of fine grinding, the finished, dried product is already in the form of a high-quality coke.
  • Tapped steam from a turbine of the coupled power plant process is preferably provided as steam.
  • the steam can be drawn off between the low-pressure part and the medium-pressure part of a three-stage turbine.
  • FIG. 1 A lignite refinement coupled with a power plant process is shown, the refinement comprising a pre-comminution 1 and a fine comminution with drying 2.
  • the pre-shredding 1 for raw lignite from the mine can only lead to a pre-crushing of mined mine moisture Include raw lignite using conventional crushers / pre-shredders.
  • the raw lignite may have been pre-crushed to a grain size of ⁇ 0 mm and ⁇ 10 mm.
  • the pre-crushed raw lignite can have a moisture content of 54% by weight, for example.

  • a hydraulic jet mill suitable for carrying out the method can comprise, for example, a regrind in which several jet tubes are immersed.
  • the jet pipes both introduce steam and, if appropriate, introduce regrind that has previously been withdrawn from the regrind bed or a regrind inlet.
  • a regrind can be discharged, for example, via a classifier arranged inside the regrind room.
