The Grate bars
Rinse the cloth frequently while wiping the grate down. Change the water in the bucket if it becomes murky and gray. Scrub the grate a second time to remove any debris missed on the first go round. Wipe the grate down with a clean cloth and water.In view of these facts it is an object of the invention to eliminate these disadvantages and to create a grate bar clamp which is simple in design and operation and which facilitates the exchange of defective grate bars. The clamp should be form-closing but it should also allow for a thermal expansion as well as the relative motion of two grate bars towards each other. At the same time it is another object to keep down the uncontrolled flow quantity and the riddlings between two fire grate bars. This object is achieved by way of the invention in that there are shoulder projections formed at the edges of the side walls of at least two neighboring grate bars towards the forced draught region being connectable with each other through a removable clamping element.
There are preferably ledge-type shoulders which are such formed to the edges that on one hand they allow a close adjoining of two neighboring side walls and on the other hand there is a distance between the side walls because of a projection formed on top of a shoulder section. Thus in a transverse view in the region of the ledge the side wall shows the shape of a foot, the side walls being adjoined with their heels. This allows to hold down the space between the two grate bars as far as possible.
The clamping element for the ledge consists of a part of a rectangular hollow section profile with a slot on one side, this slot showing a breadth which approximately corresponds with twice the width of the side wall. The hollow space itself has the same height as the projection and a breadth of approximately twice the width of the side wall plus twice the width of the projection.
The clamping element equipped like this is qualified to simply slide it over two neighboring ledges and holding them–and the corresponding fire grate bars–together. In case a defective grate bar has to be exchanged, the two or more connected grate bars must be lifted, the clamping element slid off the ledges, the grate bar taken out of its tie-down position, a new one set in and the clamping element newly slid over the ledges. There is extremely few time needed for this repair work.
