METHODS AND MELTING FURNACE OF IMMERSION COMBUSTION Russian patent published in 2018 - IPC C03B5/235 

FIELD: chemistry.

SUBSTANCE: group of inventions relates to a device for melting submerged combustion, a technological line for the production of glass products, a method for producing a molten glassy material. Device for melting submerged combustion contains a melting chamber having a side surface, a base, a vertical central axis of the melting chamber, and a mounting plane of the burners. Device for melting is equipped with a feedstock loader, a drain pipe for melt discharge and at least five burners for immersion, each of them has a central axis of the burner, respectively, and one or more nozzle outlets, a burner installation plane perpendicular to the center axis of the melting device and located at a weighted average distance relative to each of the outlets. Position of the burner is at an appropriate distance relative to the positions of its two adjacent neighbouring burners. Difference between each adjacent distance of the burner and the average value of the distances of the burners is less than or equal to 20 % of the average value of the distances of the burners. Central axis of the burner has an axial circumference that runs around the axis of the burner and has a radius equal to the measured distance from the axis of the burner to the side surface of the melting device. Difference between the radius of the axial circumference of the burner and the average radius of the axial circumference of the burner is less than or equal to 20 % of the specified average radius of the axial circumference of the burner. Melting device has a central zone in the installation plane defined between the axial circumferences of the burner in the installation plane. Central melting zone has a diameter of at least 250 mm.

EFFECT: technical result is an increase in energy efficiency.
