Better Control of the Tin Bath Temperature in Float Glass Production

The fact that physical properties of the glass as a function of temperature makes forehearth control difficult. Proper control reduces the number of rejects, which in turn increases productivity and saves energy. In float glass plants, it is especially important to control the temperature of the tin bath by controlling the various zones of the tin bath roof.
Siemens and AEG have developed an energy control system for the float glass process. The tin bath is heated in up to 40 different zones, which are carefully controlled to sustain high product quality. Together, the power consumption for the electric heating of the bath is considerable, making control also essential for control of energy use and production costs. The system minimizes power fluctuation, reduces start-up time, and increases the energy efficiency (Worrell et al., 2008. p.71).
