It considers all thermal properties of solid material and gases are invariance with temperature.
So the regenerator inlet end is damaged easier, and the requirements of the regenerator material are higher.
In the actual production, in order to avoid affect production produced by the regenerator damage, it needs to choose high refractoriness material.
