Glass Furnace Control
Glass manufacture requires a high level of accuracy and reliability in the control of the furnace to achieve consistent glass quality, to avoid energy losses and to keep emissions within legislated boundaries. Reliability is particularly important at critical stages in the process such as the furnace reversal. The T2550 PAC is designed with integral redundancy and is synchronised to a real time clock to ensure that this process can be managed safely and efficiently.

Boosting Power Control and Monitoring
Molten glass is a conductor of electricity. Passing high currents through the glass produces direct heating in the resistance presented by the glass. This heating is beneficial as it heats the 'colder' bottom glass in the furnace. This heated bottom glass rises towards the top and has a stirring effect which helps with melting and heat transfer. Boosting is often used to meet periodic fluctuations in demand or to support the pull rate of a furnace at the end of its operating life. Boosting may also help to reduce NOx emissions.
For electrical power control and monitoring in fiber glass, float glass, containers and insulation applications, you can rely on us to provide complete systems including the electrical cabinets, power controllers and necessary transformers.
Glass Annealing Lehr
Glass enters the annealing lehr at about 600°C, at which temperature it can support its own weight but still has many internal stresses. Annealing lehrs have several temperature control zones through which the glass is warmed and cooled. These must be properly monitored and controlled for consistency and quality of the glass. This cooling process is critical for the maximum yield of the finished glass.

Glass Tin Bath Roof Heating
The bath is the forming part in a flat glass production process where it is taken from the furnace spout at 1100°C and leaves the bath at 600°C when it is solid. While in the bath the glass travels through heating, fire polishing and cooling zones.
Modern flat glass systems require precise temperature control for these multiple zones. Eurotherm's control systems provide combustion or power control with multi-parameter influence.
