Use products that are designed to
integrate at all levels
Integration is an important part of systems. You can use products that are
designed to work on multiple communication platforms with connectivity at all
levels. Where appropriate, or necessary, 3rd party integration is an established
part of our solutions offering.
You can make use of our expertise in process automation, accurate control,
secure data recording and visualisation, which can be found at every level of
our systems. Maximize your system productivity with high availability
(redundancy) and use proven, standard function blocks to minimize your
engineering costs.
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.

Fuel flow/ratio control
Oxygen trim
Fuel switch over control
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 6000°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.
Multi-zone temperature control
Easy monitoring with local and central HMI solutions
Heat-cool algorithms
Speed control
Setpoint changes and control stability to 0.5°C in a range of 0-2000°C
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.
