Our honeycomb ceramic regenerators are engineered specifically for the demanding environment of ladle and tundish preheaters, delivering unmatched performance through regenerative combustion technology.
Dramatic Energy Savings: Preheats combustion air to over 1100°C, enabling efficient use of low-cost fuels. Recovers waste heat to exhaust at ~150°C, reducing fuel consumption by 30-50%.
Faster, More Uniform Heating: Achieves higher flame temperatures for superior heat transfer, cutting preheating time by 60-80%. Eliminates hot spots, ensuring even temperature distribution and extending refractory lining life by 15% or more.
Greener Operation: Promotes complete combustion, lowering CO and NOx emissions by over 50% to meet strict environmental standards.
How It Works: The Regenerative Cycle
The system uses paired ceramic regenerators that continuously alternate between two functions in a fast cycle (typically 20-60 seconds):
Heat Capture: Hot exhaust gases pass through one regenerator, transferring their heat to the honeycomb structure.
Heat Release: Cold combustion air is then directed through the hot regenerator, absorbing the stored heat before entering the burner.
This creates a highly efficient, self-sustaining loop of energy recovery.
