Flameless oxyfuel combustion technology is uniquely designed to boost capacity, reduce fuel consumption, improve temperature uniformity and lowering emissions. The combustion occurs under a diluted oxygen concentration as flue gases are mixed into the combustion zone. This slows down the oxyfuel combustion reactions and results in lower flame temperatures, which are below the point at which thermal NOx is created. The mixing of flue gases into the flame also disperses the energy throughout the entire vessel for a faster and more uniform heating. The dispersed flame contains the same amount of energy but with a much more effective heat distribution. The overall result is a more homogenous heating, a further decreased fuel consumption, and reduced emission of NOX emissions.
The OXYGON® 400 preheating system works in a flameless mode with only the pilot flame continuously visible.

Customer benefits
Up to 55% reduction of fuel consumption and CO2 emissions 25% shorter heating cycle for ladles.
Flameless oxyfuel promotes a more uniform heating to further extend refractory lining life.
Flameless oxyfuel effectively lowers NOx emissions.
Compact, simple and powerful oxyfuel installation, easy to fit on any vessel.
A hotter ladle allows for lower metal tapping temperature saving energy, refractory lining and reducing number of rejections (returns due to too low metal temperature).
A faster heating, which could reduce the number of ladles in circulation.
- Hotter and uniformly heated vessel for improved cast product quality.
