Definitions

  • the invention relates to a steam generator with several stacked dust burners with the characteristics of The preamble of claim 1.
  • the distribution channel connecting the outlet cross section of the air preheater with the inlet hoods is arranged horizontally.
  • the air preheater is provided at the height of the dust burner, which is in boxed position on two opposite walls of the combustion chamber of the steam generator Oil lances are used in the dust burner, which are used to ignite the coal dust.
  • the invention has for its object the generic To design steam generator so that its construction costs is reduced without sacrificing quality Need to become.
  • the steam generator shown is designed as a tower boiler and has a combustion chamber delimited by combustion chamber walls 2 1, to which a flue gas duct 3 connects.
  • the Steam generator can also be used as a multi-pass boiler with several flue gas flues arranged one behind the other.
  • dust burner 4 arranged in which burned coal dust with preheated combustion air becomes.
  • Way oil lances arranged for the ignition of the coal dust. If necessary, these oil lances have to be taken out of maintenance Dust burner can be removed, what behind the There is enough space for dust burners for assembly got to.
  • One or more flue gas lines 5 for discharging the in the Combustion chamber 1 generated flue gas connect the single or the last flue gas flue 3 with a flue gas flowing through it Air preheater 6 for preheating the combustion air.
  • the Air preheater 6 has a cylindrical housing 7 in which a rotor provided with storage masses rotates.
  • the housing 7 is with an inlet port 8 for flue gas, one Outlet nozzle 9 for flue gas, an inlet nozzle 10 for Combustion air and an outlet 11 for Provide combustion air.
  • the air preheater 6 is arranged in a frame 12, the vertical supports 13, 14 set up on a foundation has and that to the one carrying the steam generator Boiler frame 15 is attached.
  • the air preheater 6 is located itself at a height above the top level Dust burner 4 and is therefore above the expansion area Oil lances of the dust burner 4 arranged. Since on the expansion of Oil lances are not taken into account with this arrangement need, the air preheater 6 is close to the Combustion chamber wall 2 placed.
  • the depth of the scaffold 12 therefore corresponds to the distance of the rear wall of the Air preheater 6 from the axis of the supports of the boiler frame 15.
  • the air preheater 6 is for cleaning the flue gas Electro filter 16 downstream.
  • the electrostatic filter 16 contains a filter housing 17 with one or more Entry hoods 18 and one or more exit hoods 19 is provided. In the case shown there are two entry hoods 18 and two outlet hoods 19 are provided.
  • the inlet hoods 18 of the electrostatic precipitator 16 are via a Distribution line 20 with the flue gas outlet 9 of the Air preheater 6 connected.
  • This distribution line 20 is arranged vertically and located inside the scaffold 12 vertically below the flue gas outlet nozzle 9. Die Entry hoods 18 protrude into the frame 12.
  • the Filter housing 17 of the electrostatic filter 16 closes on the Inflow side with the rear wall of the air preheater 6 flush. This is compared to one conventional steam generator system with a horizontal Distribution line no longer any distance between the rear Wall of the air preheater 6 and the inlet hoods 18 of the Electrofilter 16 required.
  • the rear part of the frame 12 is by a single one Support 14 formed in the extension of the longitudinal axis of the Electrofilter 16 centrally between the inlet hoods 18th is arranged. This support 14 also serves Supporting the electrostatic filter 16.
  • the steam generator according to the invention by a number of other Benefits from. So is due to the vertical arrangement of the Distribution line 20 the flue gas duct from the steam generator the air preheater 6 to the electrostatic filter 16 with little wear and low loss, resulting in a reduced personal need of Overall system results.
  • the vertical flow of the Electrofilter 16 brings about a favorable coarse dust separation in front of the electrostatic filter 16.
  • the one in the vertical Distribution line 20 attached compensators are fewer susceptible to dirt and erosion than the compensators in horizontal pipes.
