Improve the efficiency of your reheating operations with our oxyfuel solutions.
If you would like maximum benefits with minimum changes to your existing operation, we recommend increasing the oxygen content using high velocity lances. Alternatively, for customers who want to maximise the benefits of oxygen and are willing to replace the combustion system, we have developed flameless oxyfuel.
Conventional oxyfuel combustion
Using oxygen instead of or in addition to air offers a number of advantages.
• For instance, oxygen eliminates the nitrogen ballast of air and thus increases the energy efficiency of the furnace.
• It also raises the concentration of CO₂ and H₂O in the furnace atmosphere. And since these gases are mainly responsible for thermal radiation, oxyfuel significantly increases thermal efficiency and heat transfer.
The REBOX® family. Customized to your needs.
REBOX® is not a "one size fits all” solution but a portfolio of approaches tailored to different furnace and application requirements.
REBOX® solutions can be incorporated into new and existing furnaces without increasing the existing footprint. They are compatible with all conventional fuels and most types of furnace, from large pushers and walking beams through rotary hearths to various batch furnaces. Our REBOX® flameless oxyfuel and REBOX® HLL applications are dedicated solutions for steel reheating furnaces. And because safety is our number one priority, our specialists always ensure that our technology complies with all relevant safety standards and norms.
REBOX® flameless oxyfuel
Ideal for:
REBOX® flameless oxyfuel solutions are targeted at operators of continuous and batch-type reheating furnaces looking to maximise production capacity.
Benefits:
• More than 50% throughput gains due to improved radiation and low flue gas volumes
• Lower flue gas temperatures and volumes allowing a shorter dark/recuperative zone
• Significant reduction in fuel consumption (up to 50%) by eliminating nitrogen ballast
• Lower NOx emissions and fuel-based SOx and CO₂ emissions
• Fuels with low calorific values can be burnt more efficiently using pure oxygen, enabling it to be used even in high temperature processes
REBOX® HLL
Ideal for:
REBOX® HLL is designed for customers looking for a simple, cost effective way of optimising reheating furnaces that can be deployed on demand and does not require major changes to the existing furnace infrastructure.
Benefits:
• Up to 25% reduction in fuel consumption
• More homogenous heating due to flameless high impulse HLL combustion
• Higher thermal efficiency and heat transfer in the installed zone
• Up to 30% less NOx emissions per installed zone due to reduced nitrogen ballast and recirculated flue gas which effectively lowers flame temperature
• Can be switched on and off only when beneficial for you
