锅炉(本体)受热面的安全性可以用单位时间内因受热面损坏而引起的平均停炉次数来表明。这种意外停炉的原因是:某些强度削弱了部件的存在,它们因锅炉在运行、结构、金属等方面的缺陷而丧失自己的安全裕度,致使其服役期大大低于正常的使用寿命。这些强度削弱部件的运行状况与其温度 The safety of the heating surface of the boiler (body) can be indicated by the average number of shutdowns caused by the damage of the heating surface per unit time. The reason for this unplanned shutdown is that certain strengths weaken the presence of components that lose their safety margin due to the boiler’s defects in operation, structure, metal, etc., resulting in significantly less service life than normal service life . These strengths weaken the condition of the part and its temperature
