CLASS 13: Steam boiler and equipment.

Fatentirt in the German Empire from January 3, 1886.

With those for burning straw or chaff equipped locomobiles, the so-called straw burning machines, are currently still the . manifold inconveniences exist, the elimination of which is intended by the present invention will. For example, with the current facilities, it is difficult to Burning moist vegetable matter to achieve a bright flame in the fire box, which makes it possible to hold steam. Furthermore, the boiler pipes are easily clogged by half-burnt straw, and with the previously usual extinguishing of glowing ashes in the ash pan by pouring water heat losses are linked, and the like.

The furnishing of furnaces intended to avoid these inconveniences for Straw burning machines are shown in the accompanying drawings in various modifications shown. One or more fire boxes are used to burn the smoke arranged with air holes provided air channels.

In the device according to FIGS. 1, 1 a, 1 b, ic and id, such air ducts d open (namely three according to FIGS. 1 a and 1b, one according to FIGS c the fire box, which is provided with a fire door opening α and a drawer b with a self-closing flap for introducing the vegetables to be burned. The channels d contain a larger number of air holes r, which are directed towards the fire door and supply secondary combustion air which flows in through the inlet e in <i.

The air ducts d with the aforementioned air holes r can, however, also open into the rear wall of the ash box c at e according to the modification in Fig. Without this changing the essence of the matter. In front of the fire door opening α there is again an introductory drawer b with a self-closing flap, while the ash drawer is provided with ash doors on the sides and in front.

These air ducts d are best arranged between the pipe wall and the hearth in such a way that, if appropriate, they also bridge the latter and prevent the boiler pipes from being blocked by half-burnt straw and the like. This arrangement avoids that half-burned straw parts attach themselves to the pipe wall in front of the pipe openings and block the latter, so that one does not have to clean the pipes every hour. The cast iron protective plates, which are supposed to prevent the pipes from being laid, also become superfluous.

Furthermore, in order not to reduce the strong embers in the fire box by water vapors that rise when the ashes are extinguished, a special extinguishing box is formed in or on the ash chamber. The water-containing extinguisher box h, Fig. 3, with door k, which allows the removal of the dead ashes, is from the ash box c by a

Claims (2)

Intermediate floor m completely separated, which is slightly curved upwards at the front and here establishes communication between c and h. Opposite this communication point there is a door z, which enables the ashes from c to be poured into the water tank /; to be able to pull. In the modification Fig. 4 with grate Z and air ducts d, the intermediate floor is arranged above an inclined floor of the ash pan c, and a single door f enables both the pulling out of the glowing ash from the ash pan and the removal of the extinguished ash the water tank. According to the modification of FIG. 5, the intermediate space is replaced by a movable partition wall η which separates the ash space from the water space s. The wall η forms a flap suspended at the top which, after being pushed back, closes itself by means of a dross to be introduced through the door opening to remove the glowing ashes from the ash chamber. According to the modification of Fig. 6, the ash space is divided by a horizontal intermediate floor, so that a lower water space is formed, into which, after opening the door, the glowing ash from the floor can be drawn in. Here the air supply ducts d open with holes r in the intermediate floor m instead of in the outer walls of the ash pan. On the side walls of the latter, the intermediate floor is fastened here by means of angle iron. The intermediate floor m according to the modification in FIG. 7 runs front and rear communication between the actual ash space and the water space. Here, too, both rooms are accessible through a single door / of the ash box c, so that the ashes can be extinguished and then removed from the machine. The intermediate floor is supported by supports. In addition, the special type of attachment of the partition m is insignificant. Fig. 8 shows e.g. B. as a final modification that the partition m can also be attached to the bottom of the fire box. The partition wall is again inclined here, so that both the lower ash chamber h and the upper ash chamber are accessible through a single door f of the ash pan. Godfather νT CLAIMS: For locomobiles for burning straw: 1. The arrangement of the channels d in such a way that the boiler tubes are thereby protected against the ingress of half-burned parts and thus against laying. 2. The arrangement of a special water area, from the hearth or the actual ash box through a partition (intermediate floor, door or the like) is separated, for the purpose, by extinguishing the glowing straw ash in this water space not to impair the intensity of the fire by penetrating extinguishing steam. In addition 3 sheets of drawings.
