SU128990A1 - Glass Melting Furnace Continuous Furnace - Google Patents

Description

Studies of glass melting baths, which have been developed in recent years, have shown that the melting of the charge in the cooking basin is due to the heat obtained by the charge directly from the torch of burning fuel, and the heat from molten glass. This latter part of the heat comes from the flare in the zone of clarification free of charge, and together with the reverse convective flow of glass melt is transferred under the charge layer to the same wall that loads the charge to the sonar wall. It was also established that under the charge layer at the drywall there is a glass mass, the degree of clarification and rO. The strength of which is sufficient for production and is much higher than in the zone of clarification.

The described furnace design allows the use of molten glass under the charge layer along the path of its natural convection currents.

FIG. 1 and 2 depict two furnace designs.

It is a basin /, divided by a vertical transverse wall 2 (dry wall) into two parts in the gaseous medium and partly in the glass melt. In a larger cooking basin, 3 stoves near the dividing wall are loaded with charge and combat. The maximum temperature is located at the opposite end wall of the same part of the basin. The smaller, production pool 4 is located on the other side of the dividing wall and communicates with the cooking pool 3 through the slot 5 in the dividing wall. The depth, location and height of the slit are set experimentally. Through this slit, the glass melt flows from the brewhouse into the working room.

It is possible to load the charge into the furnace both from the corners of the cooking part of the furnace at the dividing wall (Fig. 1), and above the slit through the dividing wall (Fig. 2). The walls, vault and bottom of the working basin should be

carefully insulated so that the glass mass is not cooled in the upstream. When it rises to the place of production, electric heating is possible. i-: In the on-point flow, the maximum Mperature is located at the end wall of the cooking basin against the separating wall. As a result of the fact that the temperature of this wall is 100–200 ° higher than the temperature of the dry steppes, the glass flows in this basin are similar to the glass flows in a conventional furnace. The glass melt moves in the upper part from the zone of maximum temperature to the sonic wall, pushing towards it and warming it up below. Here, the glass melt, cooling down, goes down, passes partially into the production pool and then moves in the lower part back to the maximum zone, where it rises up, the closure cycle.

Subject invention

Vappa is a glass furnace of continuous operation, consisting of the cooking and working compartments, interconnected by electrocution and heating of the glass mass in the working compartment, and the fact that, in order to select the glass melt from the reverse flow, , the working compartment, equipped with tenel insulation, is located on the same wall, at which the charge is loaded, the zone of maximum temperature — on the opposite wall, and the duct connecting the cooking and working compartment, is buried below OVN steklomas-sy.
