F i g. 2 is half in visionary presentation a side wall of a steamer according to the invention

F i g. 3 is a front and rear wall of the steam generator according to the invention;

Fig.4 is half of the side wall of the invention Steam generator;

F i g. FIG. 5 shows a possible embodiment in a schematic representation and drawn out vertically a meander belt guide, as it is in the invention Steam generators is used;

F i g. 6 is a schematic representation of a partial area of the front tow. Rear wall with the work equipment inlets or exits.

As from the horizontal section of FIG. I see is, the surrounding wall of the steam generator according to the invention consists of an outer skin-1 (Fin or tube-web tube) and the inner tubing of four meander strips 2, 3, 4, 5 that run across corners. How the individual meander strips are guided are shown in FIGS. 2 and 4. In FIG. 3 is a front and back wall of one according to the invention Steam generator and the working fluid inlets and outlets as well as the pipe routing are shown schematically. In detail, reference is made to FIG. 5 and 6, which will now be described. The work equipment is introduced into the meander belt via the inlet collector 6 via the lines 7 Entries are included, as shown in particular in FIG. 6 it can be seen, they are different in the area of the lower half of the meander belt 2, 3, 4, 5 arranged in pairs offset from one another, at least one horizontal pipe being carried out between the superimposed inlets and outlets is. The inlets and outlets are located at the tubes of the upper half of the meander belt over one another and in groups. In the present case, two groups of four entries each are combined. The Aastrittsseite corresponds with respect to the arrangement and position of the exits of the entrances Entry side.

Via the inlet collector 6, as can be seen from the schematic illustration in FIG. 5 can be seen, various parallel-connected meander belts acted upon, whereby these meander belts are arranged one above the other. With the embodiment of FIG. 5 it is only shown that two meander belts are fed by a single inlet header 6 and open into the outlet header 8 via the tubes T. It goes without saying that several such meander belts can be connected in parallel to one or more inlet or outlet collectors.
