A longitudinal processing direction, from charging to working, is characteristic for all existing types of continuous tank furnaces. The design of the tank furnace with the dog house at one end and the working of the glass at the opposite end fixes the scheme of the production line and the layout of the factory or department. Since, in the majority of plants, the working of the glass outstrips the melting potential of the furnace, existing designs serve satisfactorily. However, in the processing of lightweight glass products, e.g. chemical-laboratory, fine-walled containers, perfume bottles, pharmaceutical glassware, the working front does not completely utilise the furnace capacity, resulting with the furnaces working with an inadmissibly low specific-fuel consumption per daily weight of finished goods. This paper addresses the problem and suggests a solution.
