Why Honeycomb Ceramic Heat Accumulator?
In high-temperature furnaces, exhaust gas heat loss can account for 50–70% of total energy consumption when flue gas temperatures reach 900–1300°C. Recovering this waste heat is one of the most effective ways to reduce fuel costs and improve furnace efficiency.
Honeycomb ceramic heat accumulators can:
1. Recover high-temperature exhaust heat efficiently
2. Preheat combustion air to 800–1000°C or higher
3. Reduce exhaust temperature close to dew point
4. Improve combustion efficiency and furnace productivity
5. Reduce NOx and CO₂ emissions
6. Improve furnace temperature uniformity
7. Support low-calorific-value fuel combustion
Compared with traditional checker bricks and ceramic balls, honeycomb ceramic regenerators offer much larger heat transfer surface area, lower pressure loss, and significantly higher thermal efficiency.
Product Features of Honeycomb Ceramic Regenerator:
1.Excellent Heat Recovery Efficiency:
The honeycomb structure provides a heat exchange surface area exceeding 1300 m²/m³, greatly improving thermal storage and heat transfer performance.
2.High Temperature Resistance:
Suitable for long-term operation in high-temperature industrial furnaces and regenerative burner systems.
3.Outstanding Thermal Shock Stability:
Designed to withstand rapid heating and cooling cycles in regenerative combustion systems.
4.Low Airflow Resistance:
Straight-through channels reduce pressure loss to approximately 1/4 of traditional ceramic ball regenerators.
5.Energy Saving & Environmental Protection:
Thermal efficiency up to 95%
Heat recovery efficiency above 80%
Significant reduction in fuel consumption
Lower NOx and CO₂ emissions
6.Long Service Life:
Low dust accumulation, stable structure, and excellent mechanical strength ensure reliable long-term operation.
