Definitions

  • the invention relates to a method for processing and low-pollutant combustion of solid fossil fuels, which are subjected to a grinding process to a grain size of ⁇ 3 mm, to which at least one basic additive for binding pollutants is added and which are subjected to combustion at a fire bed temperature of less than 1300 ° C. .
  • Fossil fuels are regularly crushed and dried before combustion. If they are not used with the appropriate grinding fineness for dust firing, the solid fuel is compressed into briquettes or pellets at high pressure after crushing and drying. The compression of the solid fuel leads to considerable advantages in the handling of the solid fuel during transportation and storage.
  • the emission behavior of the impurities contained in the fuel is influenced only slightly by the pressing, so that there are high pollutant emissions during combustion, for example from S0 2 , HCI and HF.
  • the fire bed temperature must not be too high so as not to remove the pollutant binding in the subsequent combustion process. It is therefore known to set the fire bed temperature below 1300 ° C., the fire bed temperature preferably being between 800 and 1000 ° C.
  • the invention is based on the object of specifying an ancestor of the type mentioned at the outset which enables low-pollutant combustion of fossil, finely ground solid fuels.
  • This object is achieved according to the invention by a method of the type mentioned in the introduction, in which the ground solid fuel with the basic additive added is used for a duration of 10 to 180 min. is kept in an essentially closed reaction chamber, the solid fuel having a moisture content of> 15% and the temperature in the reaction chamber being kept above 40 ° C. and below 100 ° C., and that the combustion takes place with a fire bed temperature of 830 ° C.
  • a very similar treatment leads to a suitable treatment of fossil solid fuels, which - in contrast to the previous process technologies - are set to a relatively high humidity for mixing with the basic additive and in in a closed reaction space can be set to an elevated temperature, the reaction space preferably being heated indirectly and preferably to a temperature of about 60 ° C.
  • Subsequent pressing of the solid fuels makes it possible to produce briquettes or pellets in which the pollutants, in particular acid formers, are bound to salts with a high dissociation temperature by the treatment measures mentioned, so that when they are burned with a fire bed temperature of ⁇ 830 ° C. the bound salts in remain in the combustion residue and do not dissociate to the pollutants.
  • the invention therefore makes it possible for the first time to also provide compressed solid fuels which can be burned with a low level of pollutants, for example with an S0 2 content of less than 2%.
  • the moisture content of the mixture in the reaction vessel is preferably set to 20%.
  • a suitable alkaline additive is an alkaline earth mixture, preferably CaC0 3 and / or MgCOa, which is added to the solid fuels in a stoichiometric ratio of 1.0.
