Heating up of the furnace and dust free cullet charging
In many cases glass draining involves controlled cooling, i.e. the
temperature of the melting end is decreased until the furnace is
accessible. Controlled cooling is essential so that parts of the
plant, such as the melting end crown etc. are preserved.
Refractory damages can only be avoided by means of controlled
cooling.
During controlled cooling (or heating) any change of crown
height is controlled by means of a sensor or a probe. Both the
crown movement and the furnace temperature are supervised.
High precision bricklaying gua-
rantees the customer a furnace
with a long lifespan and many
years of trouble-free operation.
In addition to traditional furnace
construction, HORN Bau &
Service GmbH undertakes steel
construction on an international
scale.

Tapping of the furnace including drilling
Before any repair or maintenance takes place, the controlled
tapping of the furnace must be undertaken.
To do this, a number of holes are drilled at various points in the
furnace using a specialised water cooled drill.
The flow rate can be regulated using an adjustable, water cooled
damper. It is mounted directly in front of the holes and, amongst
other functions, stops the glass flow if necessary.
The hot glass flowing out of the furnace is lead to a refractory
lined funnel via a gutter. The glass is fritted by adding water,
after which it is lead away from the furnace through a series of
gutters. HORN specialists have in fact constructed gutter systems
of over 70 m in length.
Thermal regenerator cleaning
This is one of the methods for improving the efficiency of the
regenerator. During the lifespan of a furnace, condensation of
the dust that results from the melting process can lead to
clogging in the checker works.
The thermal regenerator cleaning entails heating instruments
being installed in the regenerator beneath the rider arches and
raising the temperature of the regenerator to such a degree that
the condensation melts and flows down the shafts to the rege-
nerator basement. Great care must be taken when applying this
method since negligence can lead to damage of the rider arches.
Since the control and operation of the instruments call for a
great deal of experience as well as state-of-the-art technical
equipment, customers are well advised to consult specialists such
as the HORN staff.

ling system.
With it, openings up to 580 mm deep
may also be sawn into high-density
materials. The ambient temperature
during operation may be up to 200° C
while the temperature on the inner side
of the wall may be up to 1600° C.
