Oxygen Bubblers

Bubblers improve heat transfer and uniform product quality. Taking advantage of the developments in fluid dynamics modeling and increased understanding of the melting process, the placement of the bubblers can now be improved delivering better results. The use of oxygen is preferred in the bubbler as reduces the impact of nitrogen and other inert gases and can increase the heat exchange efficiency. Introduction of an oxygen bubbler – at design stage – can eliminate the need for the relatively expensive electric booster (Worrell et al., 2008. p.60).

Energy Savings Potential

Oxygen bubblers can increase the heat exchange efficiency by 10- 15%. With the introduction of oxygen bubblers (at the design stage) a plant in Netherlands eliminated the need for electric boosters for their furnace and saved 4 million kWh of electricity per year – equal to 170 kWh/t-product (Worrell et al., 2008. p.60).
