Description

Filling shaft device for long-burning stoves for heating gas-rich, solid fuels, e.g. B. lignite, with the filling shaft washed around by the rust gases. The invention relates to the filling shaft device for long-life burners with the filling shaft flushed by the rust gases and consists in the special training such a chute device, through the long-burning stoves of the known known Type of heating of gas-rich, high-quality and low-quality solid fuels, z. B. brown coals, are only suitable.

When heating gas-rich, high-quality Fuels, such as gas, fat and flame coals, which bake together during the degassing process, and Inferior fuels, such as lignite, briquette and peat, which are dusty or granularly disintegrated, or from dusty debris from these inferior fuels in the well-known long-burning stoves with filling chute is through their clear storage in the filling shaft of the large amount of gas that forms, the passage through the fuel layer locked up under the ceiling of the hopper. The one in the upper part of the hopper developing carbonization gases escape upwards. But you can, since their amount is very large, not all due to the small ones, in the known ovens only at the top Remove the openings provided on the edge of the filling shaft. As a result, occurs in the space above the fuel layer an increased gas pressure, which to the known Smoke nuisance and gas explosions.

This is avoided by the filling chute device according to the invention, since after this the filling chute has one or more rows over its entire height vertically superimposed openings is provided, the overlapping in them, Open channels at the top and bottom lead to the trouble-free removal of the in the feed chute Smoldering gases formed at the point of origin in the entire height of the Füil shaft to back up.

In the drawing, the chute device according to the invention for example in one embodiment and in use in a long-life furnace shown.

Fig. I shows the furnace in a vertical section along line I-I of Fig. 2 and 3 and Fig. 2 in a vertical section along line II-II of Fig. i and 3.

Fig. 3 is a cross section along line III-III of Figs.

Fig. ¢ shows a cross-section corresponding to Fig. 3 through a Round furnace.

To accommodate the fuel to be burned (lignite or the like) the filling chute i with the filling opening 2 is used. The filling chute i is in the furnace arranged in such a way that its outer wall is protected from the high-temperature, Combustion gases rising from the combustion chamber4 are flushed around the in the fuel located in the hopper i before it enters the combustion chamber 4 to dry thoroughly. So that this flushing takes place on all sides and evenly and prevents the gases from being drawn off too quickly, are on the hopper i, on its outer wall, semicircular, offset from one another and inclined ribs 5 (Fig. 2) that do not completely throttle the train. These result a zigzag guide of the flue gases in the direction of the feathered arrow 6 and the dotted line in Fig.2, in addition, an automatic keeping free of the inclined ribs guaranteed by soot and fly ash. The water vapors expelled from the fuel and other distillation products pass through the in the hopper i on his entire height vertically superimposed holes 7 from and into the semicircular Channel 8 (Fig. 2 and 3) on. This is below with the combustion chamber 4 and above connected to the furnace trains 9 and io. The pre-dried fuel slips in the filler shaft i down into the actual combustion chamber 4, where its ignition and combustion he follows.

Claims (2)

PATENT CLAIMS 'i. Filling chute device for long-burning stoves for Heating of gas-rich, solid fuels, e.g. B. lignite, with from the rust gases umspü: tem filling chute, characterized in that the filling chute (i) on its full height with one or more rows vertically one above the other (7) is provided, the overlapping in them, above after the heating flues (9 and io) and open channels (8) lead down to the fire zone (4) and thus the trouble-free Deduction of the carbonization gases formed in the filling shaft (i) by dry distillation on Secure the place of origin at the full height of the hopper. 2. Filling chute device for long-burning stoves according to claim i with guide ribs on the outer wall of the feed chute, characterized by semicircular, mutually offset, the train not completely throttling inclined ribs (5) through which, on the one hand, the filling chute is flushed (i) by the hot exhaust gases rising from the fire zone (4) on all sides and evenly is designed and on the other hand, an automatic keeping free of the inclined ribs (5) of soot and fly ash is guaranteed.
