Definitions

  • the invention relates to a process for producing process steam by burning dried lignite in a steam generator, comprising drying moist brown coal in a fluidized bed dryer with heat exchanger components through which a heating medium, at least some of the water being expelled from the lignite and as vapors from the dryer is led out, the vapors are dedusted in a dedusting and the dried lignite is cooled in at least one of the fluidized bed dryer downstream cooler.
  • a fluidized-bed dryer or steam dryer is used for drying the lignite wet with brown coal before it is fired in a steam generator.
  • Fluid bed dryer provided within which the brown coal is heated by means of a tube bundle heat exchanger whose outer walls are in contact with the brown coal for a heat exchanger. At least one partial flow of the vapors discharged from the fluidized bed is compressed and fed to the heat exchanger as a heating medium, the vapors at least partially condense.
  • the vapor withdrawn from the dryer is dedusted in an electrostatic filter and burned in the steam generator after cooling.
  • the dried lignite is fed from the dryer to a cooler, which is exposed directly to cooling air.
  • the cooled lignite is then ground and burned in the form of lignite dust within the steam generator.
  • the dry coal discharged from the dryer can have an average particle size of about 0.4 to 2 mm. This can be dried in a cascade cooler, as described for example in DE 195 37 050 A1. Alternatively, the brown coal withdrawn from the dryer may be cooled in a fluidized bed cooler in which the cooling is cooled by direct contact with a cold gas, for example with air.
  • the filter dust discharged from the vapor by means of a solids separator, for example by means of an electrostatic precipitator has an average particle size of less than 100 .mu.m, so that it would be discharged as far as possible in a cascade cooler or fixed-bed cooler owing to the very low particle sinking rate and the required high quantities of cooling gas. Therefore, for example, the cooler described in DE 195 37 050 A1 is not suitable for cooling filter dusts.
  • the invention is therefore based on the object to improve the procedure according to the invention with regard to the cooling of brown coal fine dust.
  • the object is first of all achieved by a process for generating process steam by burning dried lignite in a steam generator, comprising drying moist brown coal in a fluidized bed dryer with heat exchanger components through which a heating medium, at least some of the water being expelled from the lignite and as vapors is led out of the dryer, the vapors are dedusted in a dedusting and the dried lignite is cooled in at least one of the fluidized bed dryer downstream cooler, wherein the method is characterized in that the obtained in the dedusting brown coal dust in direct contact with the dried and cooled lignite is brought.
  • the invention can be summarized in that in an advantageous manner, the already dried and cooled brown coal with a grain diameter of 0 to 2 mm is used as a cooling medium for cooling the filter dust.
  • the brown coal dust from the dedusting device for example from an electrostatic precipitator, is layered with the dried and cooled brown coal.
  • the mixing can also take place during the transport of the layered material streams.
