Sheet steel boiler

The innovation relates to a fireplace boiler according to the preamble of the main claim.

Fireplace boilers of the type mentioned, which are used to utilize the heat generated in open fireplaces, are, for example. according to DE = OS 29 23 539, GB-PS 59 42 8o and the Swiss PS 3o9 o98 known.

Such chimney boilers are either installed from the outset at a suitable location in a room and subsequently veneered or used in the interior of already existing chimneys to make a better one for such chimneys To enable heat utilization. ■

As has been found, such fireplace boilers do not yet optimally meet the requirements to be placed on them, namely with regard to proper smoke evacuation in the front area of the fireplace and thus safety against carbonization gas leakage, optimal heat transfer conditions in the area of the secondary heating surfaces and

iiii · ■ · ι ·

Prevention of fly ash deposits, especially with regard to the necessary boiler connections for the water supply and other connections.

Accordingly, the object of the innovation is to create a fireplace boiler with a simple design these requirements can be met.

This task is the same with a fireplace boiler named type after the innovation solved by what is covered in the characterizing part of the main claim.

Advantageous further developments result from the subclaims.

Due to the special arrangement and design of the channel the result is very good heat transfer and flue gas extraction conditions, because this allows the exhaust gases to flow off with little resistance, namely from the front and above the fireplace opening. However, it is very important that the duct arrangement ensures that the heating gases are well connected water-bearing sloping wall that can be acted upon is given, which provides sufficient free space at the front to attach the emergency

flexible boiler connections.

Due to the nose-like projection of the inner boiler rear wall with an angularly rising surface, a good one is on the one hand Flue gas flow into the sewer is achieved, but on the other hand there are practically no deposit areas for fly ash, apart from the fact that the sloping channel is practically directed at the fireplace opening and from there one Cleaning is readily accessible.

Heating surface enlargements are advantageous in the form of Ribs simply welded on the inside at least on the front wall of the channel and extend to the lower approach above the hearth opening.

The novel chimney boiler and other details are shown below with reference to the graphic representation an exemplary embodiment explained in more detail.

Rear rising channel 2 of the flue gas exhaust 1 at the front from a front, level, to the upper edge 4 of the fireplace opening 5 pulled down and water-bearing wall 3 and behind from the, seen in cross section, nose-shaped projecting and water-bearing rear wall 6 limited. The lower surface 7 of the nose-like projection rises slightly towards channel 2, whereby the gradient level (indicated by dashed lines) the surface 7 is directed approximately towards the center of the front wall 3.

In the upper region of the water-bearing sloping wall 9 3ind limited inwardly by the wall 3, all the connecting pieces for, for example, flow and return 11, 12 and a thermal overflow protection 19, which are thus easily accessible and are covered with a cover when installed.

As can be seen, the wall 3 is in the direction of flow extending longitudinal ribs 13 occupied. Corresponding ribs 13 'sit on the surface 7 and on the above adjoining wall of the nose-shaped projection that delimits the channel 2 on the rear side a real chimney hood, which then goes into the inclined duct leading to the flue gas outlet nozzle l6 2 pass. Fly ash can therefore practically not be in the Deposit channel 2, apart from the fact that this can easily be removed from opening 5 with a suitable auxiliary tool

the fireplace 18 can be cleaned, since the channel 2 is directed directly at the opening 5.

Since the ribs 13 are drawn down into the attachment region 14 of the wall 3 somewhat above the upper edge 4 of the opening 5 are, the entire funnel-shaped chimney area already has large transfer surfaces.

Since the return port 12 is at the top, approximately in the middle of the sloping wall 9, because of the favorable connection option is arranged, a downwardly directed aperture 15 is provided inside in the inclined wall 9, which the incoming Directs return water downwards.

In the inclined wall 9, support webs 17 are arranged for stiffening.
