  • the inner wall at least one shows the inside of the vessel with the outer chamber connecting inner water passage opening and the Outside wall at least one outer water passage opening on, so that the water supply into the interior of the vessel and the withdrawal of water from the interior of the vessel via or at least one of the outer water openings that Outer chamber and the or at least one of the inner water passage openings he follows.
  • the inner or inner water openings that the Exposed to lime-discharging hot water inside the vessel are relatively large, so that they don't grow too quickly.
  • the externally supplied Water flowing through the at least one outer water outlet into the outer chamber and from there through the at least one inner water passage opening The interior of the vessel penetrates and warms up during this time little that hardly any lime is excreted in the outer chamber becomes. Accesses the outer water outlet or openings therefore only very little lime, so that this is chosen smaller can be. In this way, the maintenance cycles of the steam generator can be enlarged without doing so Concessions to control the necessary from time to time Draining or to the stability of the water level must be made in the evaporation vessel.
  • the evaporation vessel comprises an evaporation tank, the one below Has opening, and a replaceable arranged below Lime receptacle with a filling opening, see above that excreted inside the evaporation tank Lime through the evaporation tank opening and the filling opening gets into the lime receptacle.
  • the inner the evaporation tank is not in this way Filled with lime and the excreted lime has less be removed quickly.
  • the limescale removal is also easier, especially if the lime container is replaced or is emptied before it is completely filled with lime is.
  • the double-walled part of the evaporation vessel can either on the evaporation container or on the lime receptacle or both.
  • the outer chamber or lime sedimentation surface inclined outwards, which in particular through the inside of part of the outer wall can be shaped.
  • This lime sedimentation area begins Limescale through the at least one inner water passage flow into the outer chamber, and the in lime released even before the outer chamber or the outer water outlet openings.
  • the steam generator shown comprises an evaporation vessel with an evaporation container 1 and a lime receptacle 4.
  • the evaporation container 1 has a lid 15 on which several radiators protrude into the interior of the vessel 2, e.g. Resistance heating elements are attached, wherein only one is drawn here for the sake of clarity.
  • the evaporation container 1 is about two thirds Water filled, while the water level 10 is not homogeneous due to the boiling water.
  • the generated steam is discharged via a steam line 6.
  • the evaporation container 1 is double-walled with an inner wall 11 and an outer wall 12, the one Limit outer chamber 13 and has an opening 14 below on.
  • the outer wall 12 is in the illustrated embodiment essentially cylindrical with a horizontal Lime sedimentation area 123 forming paragraph.
  • the upper Part of the inner wall 11 is also cylindrical, while the lower part is funnel-shaped, making it more excreted and blasted off the inner wall 11 or the radiators 2 Lime slips off.
  • the distance between the inner wall 11 and the outer wall 12 is approximately 10 mm in the upper part is bent outwards by bulges 113 and one guaranteed upper edge 114 of the inner wall 11.
  • the latter two indentations 112 has a flow of water between the Edge of the limescale surface 123 and her.
  • the outer chamber 13 continuously formed around the inner wall 11.
  • the inside of the evaporation vessel is over four inner ones Water passage openings 111 in the inner wall 11 with the outer chamber 13 connected.
  • the outer wall 12 are below the limescale settling area 123 two outer water openings 121, 122 arranged.
  • the inner water openings 111 have a diameter of approx. 30 mm and therefore do not grow too quickly.
  • the outside Water passage openings 121, 122 have a diameter from approx. 20 mm, so that on the one hand possible when draining entrained limestone can be washed out, on the other hand, there is no danger that after to blow the water in the evaporation vessel starts.
