How does fireproof material craze answer boiler wall thing, if why are this handled?

Boiler wall is fireproof material craze may be caused as a result of a variety of reasons, it is a few possible reasons and processing technique below:
Temperature changes: When boiler is operated, wall can get high temperature and cooling alternant influence, this may bring about fireproof material expand and contract, cause craze thereby. The processing technique can include to use more high temperature resistant fireproof material of change, and the temperature control that improves boiler operation.
Thermal stress: Long high temperature handles the thermal stress that causes wall possibly, cause craze thereby. The means of settlement may include to choose more high temperature resistant fireproof material, improve the cooling system of boiler, perhaps adjust operation parameter in order to reduce the temperature stress of wall.
Material quality: Use inferior quality or the fireproof stuff that do not fit specific applying may bring about craze. When replace or be maintained, ensure the choice is proper the fireproof material of quality and function.
Water quality problem: If boiler wall is water is cooling, water quality problem (if corrode, furring) the damaged that brings about fireproof material possibly and craze. Check water quality regularly, use proper water treatment method, can reduce this kind of problem.
Machinery is oscillatory: Long-term mechanical vibration may cause the exhaustion of fireproof material to destroy. Ensure of boiler prop up and fixed structure is good, can reduce the vibration effect to wall.
The method that handles craze may include to change the fireproof material of attaint, repair craze part, perhaps adopt preventive measure, if optimize operation condition and the data that use more high temperature resistant, heatproof stress. Before handling an issue, the proposal seeks advice from professional engineer or technical personnel undertakes check and be assessmented in the round, the step that takes in order to ensure accords with safety and technical standard.
