Definitions

  • the invention relates to a steam generator according to the preamble of claim 1.
  • This type of dedusting has the disadvantage that relatively large amounts of dust are transported through the contact heating surfaces of the boiler. To prevent contamination of the heating surfaces here, large pipe divisions must be selected, which makes the boiler very large.
  • Another disadvantage is that a deduster is also part of a boiler system, which increases the system costs.
  • a cyclone is described in GB-A-108710 which also functions as a heat exchanger.
  • Heat exchanger tubes are provided between the outer and inner jacket of the cyclone and in the exhaust section.
  • the heat exchanger tubes between the outer and inner jacket slow down the flue gas flow, so that the cyclone effect, which is based on the centrifugal force effect, is reduced.
  • the arrangement of the heat exchanger tubes in the fume cupboard is so unfavorable that they neither support dust separation nor guarantee high heat transfer.
  • the invention is therefore based on the object of improving the steam generator of the type mentioned at the outset in such a way that its dimensions can be made smaller and at the same time high dust separation from the flue gases within the boiler is ensured.
  • This object is achieved according to the invention by the characterizing features of claim 1.
  • the advantages achieved by the invention are, in particular, that due to the special design of the contact heating surfaces of the steam generator, they serve both as dust separators for the dust contained in the flue gases and for steam or hot water production.
  • the dust is extracted from the smoke gases before they enter the touch heating surfaces, so that the dimensions of the steam generator can be made smaller and an otherwise conventional deduster is not required.
  • the design according to the invention ensures that the dust in the flue gases is drawn off in the region of high gas temperatures, so that it can no longer act as images of condensation nuclei at the end of the boiler and thus the emission of pollutants is reduced.
  • the invention also makes a contribution to environmental protection.
  • a touch heating surface 1 of the steam generator 6 is arranged in a discharge part 2 of a cyclone, which is formed from water-cooled tube walls 3 and 4.
  • the steam generator can be operated as a natural circulation or as a forced circulation or forced through boiler.
  • the water-cooled pipe walls 3 and 4 can also work as natural circulation, forced circulation or forced flow heating surfaces.
  • the tangential introduction of the flue gas flow in the form of exhaust gas or fuel gas results
  • the cross section of the cyclone — FIG. 3-circular or — FIG. 4 — must be in the form of an equilateral polygon.
