Product Detail

Ceramic heat storage monolith  ( air to air heat exchanger ) , by the advantage of large specific surface area, small heat resistance, good thermal conductivity, excellent thermal shock resistance and thin web structure realize quickly exchanging heat, reducing energy in the strict sense (up to 97% of true thermal energy can be recovery) is the key to efficient heat recovery in Regenerative Thermal Oxidizers.

Dense cordierite material blocks are preferred to be used in high temperature applications due to the high chemical resistance and thermal stability.

Usage Considerations

1.The speed of temperature rise and fall should not be too fast, otherwise it will easily cause cracking in the regenerator product. Within 300°C, the heating rate is ≤30°C/h, which mainly excludes adsorbed water; when the temperature is 300-600°C, the rate of temperature rise and fall is 60°C/h, and when the temperature is higher than 600°C, the rate of temperature rise is ≤120°C/h; When the temperature is lowered, the temperature is lowered Speed ≤60°C/h.




2. In the working conditions, if there are too many nano-dusts (silicon, organic titanium, etc.), the pores of the regenerator product will be blocked, causing uneven temperature and pressure, and finally leading to product cracking.




3. If the treated waste gas contains acid or alkaline substances, the heat storage product will be seriously corroded, resulting in such as chalking and cracking, and the service life of the product will be greatly shortened.




4. Causes of ceramic block damage : Impact, thermal shock damage, rapid steam vapor explosion, gas corrosion, too  tight installation.
