Franz Kröpelin in Düren, RhId. High pressure steam boiler.

Addendum to patent 403720.

Patented in the German Empire on July 23, 1924. Longest duration: March 22, 1942.

The main patent concerns, among other things, the conversion of an existing means or Low pressure steam boiler into a high pressure steam boiler using by far most parts of the main boiler, which in the new boiler furthermore has the effect of a steam generator or a preheater exercises. The invention is in the main patent on a Stirling water tube boiler illustrates where the cylindrical steam and water spaces for the high pressure damper winding in the cylindrical

Steam and water rooms of the main boiler are housed while the actual Steam generation elements between the steam generation elements of the main boiler are arranged in the heating gas space. The invention relates to a further development of this idea and is for example illustrated by a flame tube and ίο water tube boiler. It shows: Fig. Ι a schematic longitudinal section through a high pressure flame tube boiler the invention, Fig. 2 shows a cross section through the same ι along the line H-II of Fig. Ι in a larger Scale, Fig. 3 is a schematic view of a! High pressure water tube boiler according to the invention manure,! Fig. 4 is a section through an individual part the same on an enlarged scale. According to the invention, in the water and steam space ι a flame tube boiler 2 the Dampfsammeiraum 3 (upper boiler of a high pressure boiler system) is used. The ' Steam generation elements consist of! Pipes 4 with end chambers 5, and these EIe- j elements are installed behind the furnace 6 of the boiler in the flame tube 7 of the same. The connection between the vapor generation elements and the | Dampfsammeiraum is through pipes 8 i between the end chambers S and the former; causes. The feed water is depending on the Bej may be fed to the end chambers or the upper boiler j through any line, and a line 9 penetrating the boiler shell of the main boiler 2 is used for discharge of high pressure steam. A wall 10 and fixtures 11 ensure appropriate guidance of the Heating gases through the vapor generation elements and along them. The top the flame tube is expediently lined with a refractory layer 12. As with the subject of the main patent, the steam chamber of the high-pressure boiler system is arranged in the water or steam room of the main boiler, can; when heating up or switching off and when there are other changes in the operating conditions the boiler unequal voltages in the upper boiler and its connecting pipes, which can lead to loosening of connections and even tearing of boiler parts, do not occur, as this affects the upper boiler rinsing water or the steam provides a balance. The subject of Figs. 3 and 4 is ■ an inclined water tube boiler with an upper boiler 13 ι and used in end chambers 14 and I5 Steam development tubes 16 used. A number of these are in accordance with the invention Steam generation tubes 16 through high pressure steam generation tubes 17 replaced. For this purpose, after removal of the closures 18 pipe sections 19 are in the end chambers rolled in and passed through the high-pressure steam pipes 17. The latter open at the ends into a water space or a steam collection space in the form of cylindrical boiler 20 and 21, which transversely to the main boiler 13 on Vorderbzw. The rear end of the same run, but one of which can also be arranged inside this boiler. At this special design of the boiler it is not possible to use the two parts of the high pressure steam boiler housed inside the main boiler. As a result, however, that only relatively small dimensions for these parts are necessary, it is possible to adapt them to the stronger pressures without difficulty. Known downpipes and return pipes, which connect the high pressure water space with the high pressure steam space connect, ensure a favorable water and steam movement in the high pressure system. The invention is not limited to the conversion of existing boilers, but rather The arrangement described can also be expedient for new buildings. 95 Ρλτ ε ν τ- A ν s ρ r ü c η ε: ι.
