What is the lifespan of a small-scale high-temperature incinerator lining?

What is the lifespan of a small-scale high-temperature incinerator lining? The lifespan of a small-scale high-temperature incinerator lining varies widely, ranging from 1-3 years in some cases to 15-17 years or even longer if specialized high-performance materials are used and features such as expansion joints are implemented. Factors such as thermal stress, the capillary action of molten ash, and mismatched thermal expansion coefficients can cause lining degradation, leading to cracking and spalling. Currently, the PRC Fireprint low-temperature magnetic waste pyrolysis unit has a lifespan of up to 30 years. Because the low temperatures of 50-380°C produce virtually no metal corrosion, it does not require a lining.
