"Roller grate for waste incineration; very high performance"

description

The invention relates to a roller grate for very high performance waste incineration. It relates to the formation of the largest possible grate surface through multiple subdivisions wide grate rollers in the axial direction.

Roller grates especially for the incineration of garbage are known. In many cases they consist of an inclined grate, which is formed by a number of roller grates arranged next to one another. The well-known difficulties that occur when burning the complicated fuel refuse have recently been compensated for by special guide plates in the form of reversible pockets between the individual grate rollers. However, it has been shown in practice that ever larger masses of waste are to be expected, for the disposal of which by incineration the previously used systems are no longer sufficient due to a lack of sufficiently large grate surfaces. It is not possible to hold any number of grate rollers one behind the other, because then the enclosed space is stretched too much. This takes up too much space and is too expensive. One has also tried to obtain an enlargement of the grate surface, and hence an extension of the fuel path and an enlargement of the combustion bed for waste masses characterized in that inclined grids, which are formed of juxtaposed grate rollers, gleiehodor gegenainnig above the other anordne;!, Said alu intermediate grates small Traveling grids or stair grids

Such an "enlargement of the Boston area overall by stacking grids of any kind is only possible to a limited extent, because the space is not available in the unmeasurable even in terms of height »

The inventor has therefore set himself the task of making a Y / alzengrate for waste incineration very large Construct performance within the realms of possibility and. An enlargement of the rust surface can be justified on the cost side brings with it that meet the increased requirements k & iin. that already now and especially in the near future at waste incineration plants be asked:

It is therefore suggested for very wide grids, as they are due to the enlargement of the burner bed are provided to subdivide the individual grate rollers in the axial direction and the individual To provide parts with their own separate drive. This will make the slack with the ones described above adverse consequences of jamming and other malfunctions avoided because the roller parts can be easily supported constructively, and through the appropriate regulation of the The speed of rotation of the individual roller parts guarantees the advancement of the garbage and the formation a burning bed guaranteed without stowage or fuel holes.

Since the combustion air must be supplied also regulated by the individual grate sections, the grate hoppers corresponding to the subdivisions dee roller grate and also divided 'mounted on the grate waves continuous web plates. The air then enters the grate funnel from below and flows through and cools the grate bars. To protect the web sheets, air-cooled grate bars are attached to the web sheets. The outer roller parts are built on and mounted on HcLl shafts and are driven by them and set in rotation. The middle rollers are built on shafts that are guided through these hollow shafts. These drive shafts are equipped with a flexible coupling to ensure that the bearing is statically sound.

In the drawing, an embodiment of the subject matter of the invention is shown in section.
