Bubbler Systems

F.I.C. has some disturbing news for the glass industry

Our Bubbler Systems can reduce fuel consumption, increase productivity and quality.

F.I.C. offers a Pulse type Bubbling System as well as its more favoured Variable Bubbling System.
We can supply Bubbler tubes in a range of materials.

AS THE BUBBLE RISE, THE GLASS IS DISTURBED AND COLD GLASS IS TAKEN TO THE HOTTER REGIONS OF THE FURNACE.

A bubbling system promotes a controlled disturbance in the glass flow, bringing the cooler glass from the bottom of the furnace towards the surface in a mixing action where it can absorb the heat from the flames without the use of excessive crown temperatures. The benefits are not only decreased fuel consumption and firing temperature but also a notable increase in production and quality promoted by the improved homogeneity. The superior glass flows within the furnace help to eliminate cords.

The system also has major advantages for the melting of coloured glass. The product loss due to stone inclusions in a furnace melting dark green glass could be as high as 7%.

An F.I.C. Bubbler System will normally reduce this figure to less than 1% by stimulating the convection currents so that stones are lifted into the hotter zone at the top of the furnace and so become molten.

Down time is also reduced with an F.I.C. Bubbler System. The bubbling in float furnaces causes disturbance at the bottom of the furnace thus promoting a much quicker colour change.

Quality is ensured and no unmelted batch can enter the refining area as the bubbles from our systems ‘break’ on the surface of the glass and produce a physical barrier to the batch/foam blanket.
