Abstract

In the process for burning and drying ceramic articles with the use of kiln cassettes, the mouldings are dried and burned in the cassettes, filled with solid fuel, without a transfer step. In addition, at least a part of the cassettes are used as flat cassettes, and the solid fuel is dried together with the mouldings.

Additional application to the patent application

The method according to 'linser KrfinclnnR has proven itself for firing'! " des Hers i: i''llungs |.> ro / .ossL's suchc-r j.rzeu ^ nisse can be achieved, in particular the Vm lada processes between drying and burning process, which require complex mechanics, should be omitted under the extensive use of solid fuels.

For the production of brick products in use moldings can already be downloaded from the press directly on Brenrnw'gen and the same to dry out and burn without ^i: mJ; -de - process. This method, however, only allows for uneconomical prongs and, if charcoal is used for burning, produces an ashy effect on the meat.

Object of the invention; a procedure is to be specified at ceramic products with solid fuel, e.g. bricks can be burned cleanly and there is no reloading of the dry material between the drying and the burning process. The method should also allow the use of high drilling spaces, which are correspondingly inexpensive.

According to the invention, hearth cassettes are used as drying and firing bases in which moldings are inserted and those between the cassette bottom and the ones above Formations of solid fuel before topping with Formings is stored. The filled cassettes, which are made of refractory material and at least one The bottom part consists of the dry and then the Burning process suspended. It is advantageous that fuel with a higher moisture content is also filled into the cassette bocion such as sawdust, lignite, etc. there this together with the formations the drying process is exposed. After the drying process, the stove cassettes are placed in the oven (chamber or continuous oven) where the solid fuel in the cassettes is burned and has an effect.

The inventive method is even suitable for Manufacture of cheap, mass-produced items such as masonry bricks because as o a considerable shortening of the manufacturing process permitted. No transhipment facilities like sonsi. usually required between drying and firing, rriie Forml iiigs carrier to dry eiitf a 1] .on.
