The features of the use of plow dumpers in the lines for transporting the charge and cullet to the hoppers of the loaders of the glass furnace are considered. An improved design of a plow spreader equipped with an electromagnetic vibrator is presented. An adaptive algorithm for controlling the unloading of batch and cullet from a belt conveyor is presented. The possibility of additional mixing of these materials on a conveyor belt is shown.

The dependences for calculating the density of the heat flux into the environment from the outer surfaces of the enclosure of industrial furnaces: side walls, vault and hearth, obtained from the analysis of literature data, as well as as a result of mathematical modeling of a glass furnace, are presented. On the basis of a comparative analysis of these dependencies, performed for a glass furnace, recommendations were formulated for the selection and use of formulas for calculating the heat transfer coefficients from the outer surfaces of the fence in order to more adequately determine the heat balance of the furnaces.

An improved design of a twin-screw charge loader into a glass-making furnace is presented. It is noted that changing the shape of the pushing gate and equipping it with two side sections of a trapezoidal shape allows, with additional rotation of the pusher console around its axis, to optimize the process of distributing the charge over the glass mirror in a sealed loading pocket.

Using the methods of mathematical modeling, a theoretical and computational study of thermal processes in regenerative heat exchangers of glass-making furnaces has been carried out. Based on the data obtained, recommendations were developed to improve the efficiency and service life of heat exchangers of this type. These recommendations can be used both in the design of new glass melting furnaces and in the modernization of existing glass melting complexes.

The modern systems for loading the charge and cullet into regenerative glass-melting furnaces with a horseshoe-shaped flame, built on the basis of the use of innovative loaders, are considered. It is noted that the use of such loaders in combination with adaptive control algorithms leads not only to a reduction in dust and nitrogen oxide emissions into the surrounding atmosphere, but also increases the efficiency of the glass melting process.

Various designs of hopper devices for glass batch mixers are considered. The factors influencing the shape, volume and number of the receiving bins of the mixers have been determined. The possibility of using kubels, as well as vibrating, screw and belt feeders for unloading the charge from mixing apparatus, is shown. Some variants of rotary vibration mechanisms are presented for unloading a mixture of raw materials from the receiving hoppers of the batch mixers.

The problems of enrichment of dolomite used for the preparation of glass batch are considered. A project of a lump dolomite processing line was presented, including equipment for drying, crushing and three-stage separation of crushed material. The possibility of an additional decrease in the amount of dolomite dust fraction in the finished product is shown due to the use of aerial classification
