 HORN researches forehearth firing HORN researches forehearth firing
The firing system in a forehearth is a critical and very important tool for glass conditioning and thermal homogeneity. Targeted and controlled firing results in higher efficiency and flexibility in forehearths.
The firing system in a forehearth is a critical and very important tool for glass conditioning and thermal homogeneity. Targeted and controlled firing results in higher efficiency and flexibility in forehearths.
HORN not only theoretically develops its knowledge in this area but also through practical research.
One of these practical research studies was carried out directly in HORN's workshop. The effects of different burner types on the thermal homogeneity of glass and the heating efficiency as well as the
adverse effect of the flames on the refractory material were tested on a forehearth model.
In order to simulate a real forehearth, the same cross-section dimension of a typical forehearth and the same material was used. The forehearth model was heated to normal operating temperature. In addition, the model was filled with molten glass to the same depth as in a real forehearth.
Under these conditions, the heat exchange between the superstructure, the glass surface and the combustion products could be examined realistically. The temperature of the glass at five different points, the temperature of the super-structure, the burner blocks, and inside the combustion chamber, as well as other important parameters were recorded precisely and continuously. The analysis of these test results increased HORN’s know-how regarding forehearth firing.
Once again, HORN's research and development department has taken a positive step forward regarding forehearth development.

| Cross Fired Furnace Regenerative cross fired furnaces are used for production capacities of above 220 t/d or because of space reasons also for smaller furnaces. The long flame and wide crown span are reasons that End Fired Furnaces above 450 t/d are not built any more, they are often replaced by the Cross Fired Furnaces at this range. Regenerators, burner neck and burners are located there laterally.
The doghouse is situated at the front and over the whole width of the furnace. As alternative doghouse can be designed as two small charging front building.
The burner necks are in step design and are subject to energy consumption in the different melting zones designed in different sizes. By special devices in the regenerators or in the waste gas channels the air / waste gas flow can be controlled in each burner neck.
As at the End Fired Furnace all internals like barrier wall, deep refining area, melting boosting, bubbling system or throat boosting can be installed in the Cross Fired Furnace as well.
Advantages
- For high capacity furnaces up to 750 t/d (at float furnace up to 1000 t/d)
- Temperature profile along the length of the furnace can be adjusted easily
- At suitable designed superstructure a re-circulation of the flame is possible

| Measurement and Controlequipment The technological condition of a glass melting plant´s control system determines the plant´s financial feasibility as well as the quality of the glass produced. A side from the most modern visualisation software used to support the inspection of the melting process, HORN has developed products such as the OPTIBEAM; the internationally appoied laser glass level control system.
HORN offers functional units for miscellaneous requirements, primarily:
MCC (Motor Control Cabinet) and -electronic within the low voltage range
Measurement and control technology
Control aund automation technology
Process supervision technology
To control and govern the complex technological glass melting process, HORN has developed a four-level operational concept. The aim is to display technical parameters in the clearest and most user-friendly way and at the same time achieve the highest possible safety level.
Process supervision and visualisation
PLC - levels with independent operating units
Back-up hardware levels
Manual operation level
HORN furnaces are fitted with individual measurement and control equipment, the main elements of which govern and control the following operating parameters:
Glass levels
Furnace pressure
Temperature
Measurement of the Oxygen and CO2 in the furnace atmosphere (Optional)
Furnace camera
