Thermal Fatigue Life Prediction of Ventilation Air Methane Oxidation Bed
Thermal flow-reversal oxidation is the main technology that can effectively reduce emissions of ventilation air methane. As the core component of coal mine ventilation oxidation devices, honeycomb ceramic oxidation beds play a decisive role in the functionality of these devices. The thermal fatigue...

The results of the fatigue experiment indicated that in general, the bending strength of mullite ceramics decreases as thermal shocks increase.
