Introduction of Refractory Honeycomb Ceramic Regenerator

Refractory honeycomb ceramic regenerator (also called a ceramic regenerator, or refractory ceramic block), honeycomb ceramic regenerator is the main component of high-temperature air combustion technology. It has been widely used in various heating furnaces such as pusher-type heating furnaces, walking-beam heating furnaces, heat treatment furnaces, forging furnaces, melting furnaces, firing furnaces and ladle heaters, soaking pits, radiant tube burners, lifting furnaces, blast furnace hot blast stove, etc.

Refractory honeycomb ceramic regenerator is a kind of porous ceramic. The regenerator is the key component to stop heat and reduce harmful gas emissions. It is widely applied in all kinds of HiTAC (High-temperature air combustion) step-type heating furnaces, RTO (Regenerative thermal oxidizer) Etc. we can produce honeycomb ceramic regenerators with many kinds of raw materials, such as cordierite, mullite, corundum-mullite, Carborumdum, Zr-Cr corundum, etc. The advantages of ceramic regenerators can improve heat exchange conditions in the furnace, and utilize low calorific value fuel. Reduce heat loss, utilize the energy the most, and reduce operation capital. Reduce harmful gas emissions, and produce more friendly.

Features of Refractory Honeycomb Ceramic Regenerator

1. Various materials, according to customers and different environments, choose different materials and specifications of products.

2. The hole wall is thin, the capacity is large, the heat storage is large, and the space is small.

3. The hole wall is smooth and the back pressure is small.

4. Long service life, not easy to scum, high-temperature deformation after drinking.

5. The product has high quality specifications. During installation, the heat storage bodies are discharged neatly with little misalignment.

6. Good thermal shock resistance, good thermal conductivity, and high mechanical strength.

Characteristics of Refractory Honeycomb Ceramic Regenerator

Honeycomb Ceramic Regenerator has low heat expansion, high specific heat capacity, high specific surface area, low-pressure drop, low thermal resistance, good thermal conductivity, thermal shock resistance, and much more. So, in metallurgy and chemical industries, it’s used as HTAC, while we combine recycling the heat of the emissions, highly efficient combustion with reducing NOx. It becomes a true energy saver and decreases Nox.
