The invention relates to a method for boot heaters with heating elements for downloadable material glass devices, and downloadable material is placed on the upper heating elements with uniform distribution, controlled by sensors.

Publications relating to the preparation of feed material for glass furnaces, there are already several decades, in many cases draws attention to the tendency for bonding mixtures with different components. The mixture in the glass due to the very different target destinations. The reasons for the propensity for bonding components are very diverse and are based on very different melting points, viscosities, sizes and shapes of particles, and thermal and mechanical factors affecting road transportation before melting. A particularly negative effect when this recorded with downloadable material is free or bound water and water vapor introduced from the exhaust gases to preheat and heat recovery from downstream of the cooking basin. The condensation of the evaporated water promotes bonding. Another negative factor is the hopper to feed material in which the material is uncontrolled and uneven fit with what oame over the top of the heating pipes and in which, again, is condensed water vapor.

From the publication US 7494948 B2 it is known that stack freely flowable mass of the loaded material component glass for glass furnaces respectively in the wet (cheese), or at temperatures below 35°C or heated to a temperature of 100°C or higher before you bring them to the furnace. When this wet feed material must contain the free fraction of water from 2% to 10% and from 0.0001% to 5% of surface-active material, preferably water-soluble Soaps, such as carboxylate from 4 to 22 linked atoms With. you can put the wet feed material and to heat at least up to 150°C, and it remains without deposition freely flowing. The author reports that prior to its invention, it was impossible to load the heater wet downloadable material, as at temperatures of 100°C and above inevitably occurred sintering mass. The publication does not specify the size of the particles, however, with reference to the publication EP 1123903 A2 reported that without the described device with electrostatic dust separator may be environmental pollution by fine particles of dust.

From the publication DE 102008030161 known heat exchanger, having a form mine for preheating the mixture of glass particles for glass furnaces through which the smoke is off gases from the heating system of the furnace are directed to alternate and winding horizontal flue gas channels. The heat exchanger has numerous vertical and rectangular cross-section channels of molten material that intersect with transverse offset from the flue gas channels and connected to each other through the openings in the channel walls so that water vapor from the vertical channels of molten material will be otkazyvatsa in the transverse direction so as to prevent the entrance of the flue gases in the channels of molten material. However, it is not excluded that, due to the remoteness of these holes in the walls of the mine and due to the long horizontal paths of flow within the molten material remains wet, resulting in bonding of the particles of molten material and the blocking of its filing.

None of the above documents does not solve the problem of distribution of feed material evenly and most thin layer to the uppermost flue gas channels or over them and maintain this status.

The task of the invention is to provide a method described above kind in which the distribution of the feed material occurs with the greatest thin but uniform layer thickness on the upper heating elements and between them, in order to effectively deter or prevent bonding of the particles and the jam movement the Oia downloadable material.

The solution of this problem is carried out according to the invention by the above method using the fact that

a) above the upper heating elements have a distribution device at least three rotary distribution plates, rotary axes which are horizontal edges of the virtual prism (P), and

b) the upper distribution plate resets the feed material with alternating one located beneath the distribution plate, which, for its part, resets received downloadable material on one of its sides, and

(c) divider plates are regulated by the sensors with the scheme of data processing and management and regulatory authorities, the relevant distribution plates, with the purpose of uniform distribution of the surface of the charged material in the cross section of the heater.

Due to this, the problem is solved in full, in particular the feed material is distributed with most thin but uniform layer thickness on the upper heating elements or between them, so that effectively restrains or prevents adhesion of particles and the jam movement of the loaded material.

The invention relates also to a device for loading the conditions of the heaters, containing switchgear and heating elements for downloadable material for the glass-melting device, and the feed material is placed on the upper heating elements with a uniform distribution by adjusting the sensors.

To solve this problem and achieve the advantages of such a device characterized in that

a) above the upper heating elements are located switchgear at least three rotary distribution plates, rotary axes which are horizontal edges of the virtual prism (P), and

b) the upper distribution plate may interleaved rotatable between two end positions, in which the feed material may be disposed on one located beneath the distribution plate, whereby respectively caught by the feed material may be disposed on one side down, and

(c) divider plates can be adjusted by the sensors with the scheme of data processing and management and regulatory authorities, the relevant distribution plates, with the purpose of uniform distribution of the surface of the charged material in the cross section of the heater.

For the following in the of Panini invention particularly preferably, if, either individually or in combination:

- the top axis is in the vertical mid-plane (M-M) switchgear, and under it there are two other axes with their distribution plate in mirror-symmetrical arrangement on both sides of the vertical mid-plane (M-M) switchgear;

- way sliding of the two directed to each other in the position of the alignment distribution plates, respectively, is limited to a single deflector plate located on the section of the region of the switchgear,

- sensors are arranged in a horizontal matrix located in a horizontal plane at the upper end of the heater,

sensors are gaps between the upper heating elements, and/or, if

- switchgear is installed at an angle in a mirror-symmetrical arrangement of two walls, a virtual extension which runs into the middle plane (M-M).
