FIELD: glass.
SUBSTANCE: invention relates to glass industry and can be used in processes related to loading charge and glass scrap in regenerative glass furnaces with U-shaped direction of flame in production of glass containers and other articles from glass. Alternate loading of charge and glass scrap into two loading pockets arranged on lateral sides of the furnace is made with the help of two loaders having two independent pushers and two parallel tubular vibrating feeders each. One of the vibrating feeders is installed inside the loading pocket on the side facing the front end wall of the furnace and loads into the furnace its own return glass scrap from the corresponding intermediate hopper. Second vibrating feeder is displaced inside the loading pocket by 300…400 mm towards the glass production and supplies the furnace with a mixture of charge with delivered glass scrap from the other intermediate hopper, herewith separate loading of the own return glass scrap is performed mainly on the side of the furnace contacting with exhaust flue gases. Combined supply of the own return glass scrap and the mixture of charge with delivered glass scrap, at which pushing the loaded piles of the mixture of charge with delivered glass scrap is performed more intensively, than pushing the loaded piles of the own return glass scrap, is performed only on the side of the furnace contacting with the flame, herewith 3…5 minutes prior to changing the flame direction and the end of each regeneration cycle, duration of which is 20…30 minutes. Loading the mixture of charge with delivered glass scrap from the side of the furnace contacting with the flame is stopped leaving only loading of the own return glass scrap, and it is resumed from the other side of the furnace in the next cycle of the exhaust flue gases heat regeneration.
EFFECT: technical result is decrease of dusting and charge loss during loading, reduced wear of refractory masonry of the furnace in the boiling pool and higher efficiency of melting charge and glass scrap.
