DE346252C - Device for loosening, mixing and moving fuel on fire grates - Google Patents

Description

Device for loosening, mixing and any movement of fuel on fire grates. To achieve full utilization of Fuels, roasted goods and the like on stoves, fire grates, etc. are different Devices have been proposed. One has z. B. so-called high-performance celebrations built, in which a mechanical loosening and mixing of the fuel is to be achieved in that all grate bars are suspended pendulum and from From time to time a shaking movement run, making the bar overlay Fuel is shaken tuid mixed. There are also inclined grids used, in idenen the fuel by temporarily advancing part of the Grate bars are loosened and made to slide off; could.

Traveling grates have also become known; which either in the Grate chains themselves or below them special devices are arranged, which serve to loosen up on the grate and with this migrating fuel.

With all these grate designs, however, the limit of the possible Impact is not achieved and the means used are involved, expensive and: operationally insecure.

In contrast, the new invention provides a very simple arrangement -dar, .that is easy to attach, change and handle, in which the Loosening and mixing the fuel with simple means at the highest Efficiency is achieved. The invention consists in that by the to be moved. Fuel pulled through chains or similar link bodies in a suitable manner which cause the loosening up and the mixing together. The chains can be moved in any direction, e.g. B. parallel to the floor surface or at an angle, horizontal or rising '. or descending, forwards or backwards, etc., depending on how to influence the movement of the fuel layers. Also can be different Chains are moved in different directions and at different speeds. For example, in the case of traveling grids, you can also change the grate and chain speed as well as the corresponding direction of movement of the chains cause the upper Fuel layers faster or slower than the lower ones, if desired also move in the other direction.

Ab-b ,. z and 2 show, for example, an embodiment of the invention in a traveling grate furnace. a is the traveling grate, b the coal bunker. c, d _ and e are individual chains that are guided over corresponding guide devices. The movements of the chains can, for. $. be controlled in such a way that all or individual chains initially move in the direction of the ash fall, whereby upper layers of coal get on lower ones that are already glowing. If the chains are then allowed to move in the opposite direction, layers of carbon are retained or returned. In this way you can achieve that the coal takes more or less winding paths, is mixed well and lingers longer on the grate, which always remains evenly covered.

Fig-. 3 and q show, for example, two forms of application of the chain pick in generators. In Fig. 3 both a vertical and an inclined guide of the chain is shown. Through the latter will. a helical movement of the contents to the ash fall is achieved. Fig.q. shows that in plan. Such a helical movement comes about through the chain strands, which are obliquely offset on the circumference, of which a, Ir, c and d represent the upper "and ä , b ', c and d' the lower.

That with apparatus (such as generators) gases, fuels and the like the chain holes get to the outside, you can in a known manner by the counter pressure Injected liquids, gases or vapors, prevent by removing the guide nozzle for the chains z. B. gives the form shown in Fig. 5. One can do the same also in a known manner by -suitable, z. B. switchings submerged in water as shown in Fig. 3, for example. Where the ITettes get very hot you can provide a special cooling by cold air, water or the like. Provide by z. B. the chains on their way outside the hot zone through water be performed, as can be seen from Fig. 3.
