FURNACE WITH SUBMERSIBLE BURNER Russian patent published in 2022 - IPC C03B3/00 C03B3/02 C03B5/12 C03B5/235 

FIELD: furnaces.

SUBSTANCE: invention relates to a furnace with a submersible burner, in particular, suitable for reusing fragments of mineral wool, with the advantage of energy efficiency. Apparatus for melting a glass-making material includes a furnace equipped with at least one submersible burner, a system for supplying flammable gas and a combustion-supporting substance to the submersible burner, a system for supplying source material containing fragments of mineral wool into the furnace under the surface of molten glass-making material, a system for supplying source material into the furnace, including a channel suitable for receiving source material through the upper end and passing the source material downwards to the molten source material. The channel is suitable for receiving gaseous combustion products discharged from the furnace and passing said products upwards through the source material in the channel. The apparatus is equipped with a supporting tool for solid source material in the channel, located above the surface of molten glass-making material, suitable for retaining solid source material in the channel, and suitable for the molten source material flowing down into the molten glass-making material to pass through said tool, and suitable for gaseous combustion products discharged from the furnace rising in the channel to pass through said tool. The system for supplying source material into the furnace under the surface of molten glass-making material is configured to push the source material into the molten glass-making material.

EFFECT: possibility of increasing the heat transfer efficiency and melting mineral wool fragments quickly.
