Description

The invention relates to the industry of building materials, in particular to devices for the production of glass, and can be used in glass melting furnaces when loading charge and glass.

The purpose of the invention is to reduce energy costs for melting glass and reduce losses of volatile components.

FIG. shows a diagram of a glass furnace; figure 2 - node burner.

The glass-melting furnace contains a cooking basin 1 with burners 2 and a system 3 of translation of the direction of the flame, charge loaders 4 and glass cullet 5, and uro-number 6 glass mass. In the bottom 7 of the first pair of burners 2, loading chambers 8 with ducts 9 connecting them to the cooking pool 1 are installed, and glass-loader loaders 5 are placed above the loading chambers 8 in the roof of the 10 burners and interact with the glass melt level gauge 6 and the furnace direction translation system 3 Kiln contains a block 11 for controlling the feed rate of the charge and a block 12 for controlling the feed rate of the broken glass. The loader 5 of broken glass consists of a hopper 13 and a feeder 14 with a hopper 15. The gas in the burner 2 is introduced through the inlet 16.

Loading of the charge and glass into the glass melting furnace is performed as follows.

The mixture is supplied by the charge loader 4 to the cooking basin 1 continuously at a predetermined speed set by the charge rate control unit 11. The feed rate of the charge is set for the calculated nominal capacity of the glass furnace. For an established calculation of the ratio of the charge and the glass on the glass feed rate control unit 12, the glass flow rate is set. The inclusion of feeders 14 loaders 5 glass from one or the other side of the glass furnace is produced by

commands from the translation system of the flame direction 3 so that the tattel 14 fed the cullet into the loading chamber 8 through under the 7 inactive burner 2. The cullet is fed by the feeder 14 from the hopper. 13 through the feed funnel 15 into the feed chamber 8, where it melts under the influence of the heat of the exhaust gases from the glass melting furnace.

When the glass is dropped from the charging funnel 15 into the loading chamber, dust in the waste gases, in particular sulfate, is trapped. In the loading chamber 8, opposite the operating burner 2, the cullet also melts under the action of a torch (radiation from the burner masonry). The melted glass from the loading chamber 8 through the duct 9 is fed into the cooking basin 1. The flow rate of the broken glass is corrected depending on. bridges from glass melt level. So, if the glass mass level decreases from the set value, then at the output of the level gauge 6 of the glass mass a signal appears that increases the glass feed rate. When the glass mass level rises, a signal is given to decrease the glass feed rate. Due to the fact that the supply of the charge to the furnace remains always unchanged, and only the flow of glass depending on the level fluctuations varies only within certain limits, the boundary of the glass melting zone remains stable.

The advantages of the proposed device are the reduction of energy costs for glass melting due to more efficient use of heat from waste gases and stability of the glass melting zone, improving the quality of glass mass due to the stability of the glass melting zone, extending the service life of the furnace due to reduction of dust from the regenerators and reducing littering the environment.
