Power Plant Boiler Lining Life

　　Power plant boiler lining life refers to the time during service that the refractory covering inside the boiler can maintain its design performance and integrity. The life of power plant boiler lining is affected by many factors, and it is necessary to adopt effective evaluation methods and maintenance measures to prolong its service life and ensure the normal operation and safety performance of the boiler. The following is a detailed introduction to the life of power plant boiler lining:

　　1. Factors affecting the life of power plant boiler lining: There are many factors that affect the life of power plant boiler lining, including fuel characteristics, combustion temperature, flue gas composition, chemical corrosion, mechanical shock, thermal stress, etc. These factors will have varying degrees of impact on the lining material, accelerating its aging and damage.

　　2. Life evaluation method of power plant boiler lining: For the life evaluation of power plant boiler lining, regular inspection and evaluation are usually required. Commonly used methods include non-destructive testing (such as ultrasonic flaw detection), destructive testing (such as sampling testing) and actual operation monitoring. Through these methods, the damage degree and remaining life of the lining material can be evaluated, and corresponding maintenance plans and replacement programs can be formulated.

　　3. Ways to extend the life of power plant boiler linings: In order to prolong the life of power plant boiler linings, various measures can be adopted, such as optimizing the combustion process, controlling flue gas components, reducing thermal stress and mechanical shock, etc. In addition, the selection and design of lining materials also need to take into account factors such as its corrosion resistance, high temperature stability and wear resistance.
