Mullite honeycomb ceramic heat storage body is a honeycomb ceramic heat storage body made of mullite (mainly composed of aluminosilicate minerals) as the base material. It is widely used in industrial high-temperature heating equipment (such as hot air furnaces, industrial kilns, etc.) to recover waste heat of flue gas and preheat combustion-stimulating air or gas.

advantage

1. Excellent high temperature stability

Mullite materials have high refractory resistance (about 1750℃~1850℃), which is not easy to soften or deform under high temperature environments, and are suitable for long-term operation in high-temperature conditions above 1000℃.

The thermal expansion coefficient is low, the thermal shock resistance is good, and it can withstand frequent hot and cold cycles, reducing cracking or damage caused by thermal stress.

2. High heat storage efficiency

The honeycomb structure design greatly increases the specific surface area, significantly increasing the heat exchange area between the gas and the heat storage body, and improving the heat transfer efficiency.

The gas flow resistance is small and the flow uniformity is high, which is conducive to improving the efficiency of the heat storage and heat release process.

3. Strong corrosion resistance

Mullite materials have good corrosion resistance to acid and alkali environments, molten ash slag, etc., and are not easy to react chemically with corrosive components in the flue gas, extending the service life of the heat storage body.

4. Energy-saving and environmental protection

By recovering the waste heat of flue gas, fuel consumption and pollutant emissions (such as NOx) can be significantly reduced, meeting energy conservation and emission reduction requirements.

The heat storage body itself is free of harmful substances and is environmentally friendly.

5. Compact structure and easy to install

The honeycomb ceramic heat storage body has a small bulk density and light weight, making it easy to install and maintain.

Modular designs can be flexibly combined according to requirements to adapt to industrial equipment of different sizes.
