Cullet filling service for Glass Furnaces

At Traterme, we offer specialised solutions for cullet filling in glass furnaces, a crucial step following the construction, repair, or maintenance of furnaces. This process must be carried out in a controlled and efficient manner to ensure that the furnace reaches its optimal operational level without compromising the quality of the glass or the integrity of the furnace.

Why is controlled cullet filling important?

Cullet is essential in the production of new glass, as it is used to initiate and stabilise the melting process. However, this material must be introduced carefully into the furnace to avoid issues such as dust accumulation, blockages, or imbalances in the melting process. Improper filling can lead to inefficiencies in melting, contamination, or even equipment damage.

At Traterme, we ensure that the cullet is loaded at a controlled rate and evenly distributed, tailored to the specific needs of each plant and furnace.

Our filling methodology

We employ two main techniques for cullet filling, chosen based on the furnace's characteristics and process conditions:

• Blowing techniques: Using compressed air, the cullet is blown into the furnace evenly. This method is ideal for larger furnaces or when rapid and efficient distribution is required without creating blockages or material build-up.
• Vibration techniques: Controlled vibration systems progressively feed cullet into the furnace without generating excessive friction, preventing material compaction or accumulation in specific zones. This method is particularly useful in smaller furnaces or when precise placement of the cullet is needed.

Technology and Benefits

• Uniform and controlled loading: We ensure that the cullet is loaded at a consistent and appropriate rate for each furnace, preventing dust formation or blockages.
• Adaptability: Our blowing and vibration systems allow for adjustments in filling speed and volume, ensuring the cullet is loaded according to each plant's parameters.
• Furnace protection: Controlled filling minimises thermal and mechanical stresses that could damage the refractories or compromise the furnace's lifespan.
• Energy consumption optimisation: Efficient cullet filling allows the melting process to start more quickly with less energy consumption, optimising the overall plant performance.

Cullet filling often follows furnace draining or repair phases, where our controlled cooling service plays a key role. At Traterme, we integrate these services to provide a comprehensive solution for glass furnace maintenance.
