SU41998A1 - The method of burning caps - Google Patents

Description

In the technique of firing various materials, it is known to use calcining kilns with vertical retorts and adapting to them for loading the furnace with material to be fired from one end and unloading the finished product from the other.

The present invention relates to methods for continuous calcining of the droplets with ceramic masses contained therein or products of them in the calcining muffle devices in the form of vertically supplied outside heated pipes loaded from above and discharged from the bottom.

The main disadvantages of creatures of lean types of kilns for firing of ceramic masses and products from them are the large expenditure of heat on heating the masonry of stoves, caps that have a relatively large mass compared to the mass of baked objects moving trolleys and emit it into the surrounding space. Great inconvenience before (376)

at the same time, especially for periodically operating furnaces, the difficulty and high cost of loading and unloading products from the furnaces.

I (the proposed method of firing ceramic masses and products from them is aimed at eliminating to a large extent many of the aforementioned drawbacks, by feeding hot glowing trays after passing the zone of greatest heating to the trolleys through the lower mouth of the kiln.

In the attached drawing of FIG. 1 shows an exemplary embodiment of the proposed furnace in a vertical section; FIG. 2 is the same cross section; FIG. 3-vertical section of a part of the furnace with capsles loaded with the product.

The furnace consists of a special design, carefully insulated from radiation losses and heat transfer from the heating chamber 2 (Fig. 1 and 2), with burners and openings 16, 17 for exhaust gases placed in it; wherein the outlines and dimensions of the chamber of defined gases in the chamber of the respective device, characterized in that the hot glowing droplets with the products directly, after passing through the zone of greatest heating, produce

on the trolleys through the lower mouth of the furnaces into the space under the latter with the help of a lowering, supporting rod, passed through the hole in the bottom of the trolley.
