A study, on models, of the effects of operation and design on the glass flow in tank furnaces

JSGT 1957 V41 T259-T275

The pattern of currents in glass contained in tank furnaces has been studied using transparent 1:20 scale models. Endeavours were made to maintain similarity, using the Gallileo Number as a criterion, glass being represented by a liquid phenolic polymer. A concept of a 'refining factor', which combines viscosity and time, has been introduced to judge the effects of operation and design factors on the pattern of currents and their velocity. Examples are given of the effects of the thermal barrier position and of the location of the throat.
