据《Электрическиестанции》2011年5月号报道,对各种锅炉水冷壁管热力破坏的分析表明,这些破坏的原因是由于管子周边单侧加热在金属内产生过度的轴向热应力。分析了在管内形成积垢的条件下,锅炉水冷壁管工作的温度条件。给出了有关水冷壁管强度计算的
Analysis of the thermal failure of various boiler waterwall tubes shows that the cause of these breakdowns is the excessive axial thermal stress in the metal due to the unilateral heating around the tube, according to the report of “Электрическиестанции” May 2011. The temperature conditions of the boiler water-cooled wall tube were analyzed under the condition of fouling in the tube. Gives the calculation of the strength of the water wall tube
