Description

885394

The invention relates to an ignition grate for traveling grids which can be moved on one side Supported grate members, consisting of a slanted under wind grate and a self subsequent plan grate, which is based on the traveling grate.

The purpose of the invention is such grates that are suitable for burning inferior quality, in particular Strongly water-containing fuels, such as ίο raw lignite and the like, are used, so train that a perfectly even distribution of the glowing coal particles on the Rust path is guaranteed, so the basic fire cannot tear off. According to the invention, therefore, the bars of the plan grate are in the vicinity of their pivot point attached projections on the forming step-like η grate track of the traveling grate freely. Bring one here

so the projections with which the grate bars rest on the traveling grate, alternately in at different distances from the fulcrum, this results in a finger-like one Shaking motion that causes the glowing coal

»5 particles evenly across the entire width of the Moving grate distributed, blockages in the spaces between the grate bars prevented and influences the air supply favorably. The fact that the grate bars of the plan grate are Support the traveling grate at a point where it is only in the process of being formed when you turn back is, so stair-like, with the advancing movement constantly changing paragraphs forms, in itself offers a guarantee for a?

vigorous movement of the individual rods around their pivot points. But there is also the point of contact between plan grate bars and traveling grate in the vicinity of the pivot point of each If the bars are laid, there is another one

Large-scale translation, so that the rods swing at their ends at the front, which is a multiple of that which is due to the stair-like gradations of the Moving rust are caused.

In the drawing, an embodiment of the subject invention is shown, and although show:

Fig. Ι a vertical section through the front part of a traveling grate and Fig. 2 a part of the device in plan. The ignition grate consists of the sloping under wind grate a, to which a short! Plan grate b adjoins. This plan rust ■ b is made up of individual grate bars c, d together sitting on the rotatable elle after the forward-looking rust to end on a common W ^T e and with their noses η on the limbs r! of the traveling grate rest. These noses η are designed to be of different lengths, that is to say in ver! at different distances from the pivot point of the j rods, for example so that all! Rods c have a longer nose, all rods d a shorter} nose. The consequence of this is that the bars with a longer nose lag behind those with a shorter nose, during the oscillating movement of the grate bars c, d about their axis e caused by the step-like gradation of the traveling grate. The rods are therefore constantly shifting against each other and in this way prevent the gaps from becoming blocked, while the oscillating movement itself ensures that the material to be fired is transported even further.

There are the most diverse structural changes both in terms of the oblique as The plan grate is also conceivable, due to the design of the traveling grate, the peculiarity of the Fuel or by other circumstances, without thereby outside the scope of the invention to fall.

Claims (2)

Patent Claims: 1. Ignition grate for traveling grids with one-sided movably mounted grate sections, consisting from an inclined under wind grate and an adjoining plan grate, which is based on the traveling grate, thereby characterized in that the bars of the plan grate with projections attached in the vicinity of their pivot point on the in formation grasped stair-like grate path of the traveling grate rest freely. 2. ignition grate according to claim 1, characterized in that the projections with where the grate bars rest on the traveling grate, alternately attached at different distances from the pivot point are. 1 sheet of drawings.
