The service life of ceramic fiber module is a complex problem, which is affected by many factors. The following is a detailed analysis of its service life:

I. Service life range of ceramic fiber module

The service life of ceramic fiber modules usually ranges from several years to more than ten years. Under ideal conditions, its service life can reach 5 years or even longer. However, under some extreme or harsh working conditions, its service life may be shortened to several months.

II. Main factors affecting service life

Material quality: high-quality ceramic fiber modules usually have higher heat resistance, corrosion resistance and wear resistance, and can work stably for a long time in high temperature and harsh environment.

Working temperature: The degradation speed of ceramic fiber module will be accelerated when it is close to its maximum service temperature (such as 1350℃).

Thermal stability: frequent temperature fluctuations (such as rapid cooling and rapid heating) will lead to microcracks in ceramic fiber modules, thus affecting their service life.

Chemical environment: the chemical atmosphere in the kiln (such as oxidizing, reducing or neutral) will affect the chemical stability of ceramic fiber module.

Mechanical vibration: Mechanical vibration during operation may lead to loosening and damage of ceramic fiber modules.

Maintenance: Regular cleaning, inspection and timely repair of damaged modules are the key to extend their service life.

III. Ways to prolong service life

Material modification: by adding high temperature resistant materials such as alumina and zirconia, the fire resistance of ceramic fiber module can be enhanced.

Structural optimization: adopting multi-layer structure or composite structure can disperse thermal stress between different levels and improve the overall stability.

Construction technology improvement: operate in strict accordance with the construction specifications to ensure the close fit between modules and avoid cracks and holes.

Regular maintenance and monitoring: establish a regular maintenance and monitoring system to find and deal with problems in the use of ceramic fiber modules in time.

IV. Practical application cases

In the renovation project of a high-temperature kiln in a glassware factory, the high-temperature resistance and thermal shock resistance of the ceramic fiber module were significantly improved by adding alumina fiber and adopting multi-layer composite structure design. In the actual operation of the reformed kiln, the service life of ceramic fiber module is prolonged by about 30%, and the energy consumption of the kiln is reduced by about 15%.

To sum up, the service life of ceramic fiber module is affected by many factors. By optimizing materials, structure and construction technology, and strengthening maintenance, its service life can be effectively extended, thus improving economic benefits and energy-saving effects.
