Ceramic honeycomb, as an efficient heat exchange element. It plays an important role in high temperature environment such as heating furnace. However, during use, the ceramic honeycomb may suffer damage, affecting its performance and life.
In the field of ceramic technology, the selection of honeycomb material is a crucial link.https://www.rtoceramic.com/
This structure performs well in high temperature, hot and cold environments. But its performance depends largely on the material chosen.

- Use environment
In the furnace environment, the iron oxide contained in the oxide sheet . And the material itself plays a crucial role in the fire resistance of the honeycomb. - Design factors
In regenerative reheating furnace, the double regenerative mode is dominant. However, due to the large size of the air and gas nozzles. the flow mixing effect between the two is often unsatisfactory. Which may lead to incomplete combustion. When the residual air and gas enter the narrow space inside the honeycomb. The re-mixing between them may trigger secondary combustion. And it can cause damage to the honeycomb. - Honeycomb structure
In the process of designing and manufacturing ceramic honeycomb. The choice of hole spacing and wall thickness is a crucial engineering decision. These two parameters are not only directly related to the change and distribution of temperature field. In the process of heat absorption and heat transfer.But also the key factors affecting the service life of honeycomb.
If the hole distance is too small, it is easy to cause dislocation during installation. Which greatly reduces the effective flow area of gas and increases unnecessary resistance loss. - At the same time, too small hole spacing may also lead to thermal stress concentration, accelerating fatigue and failure of the material. On the contrary, too large hole distance means that the heat exchange between the gas and the honeycomb is insufficient. Resulting in a decrease in thermal efficiency and poor heat exchange effect.
