All-around experiments on the temperature of the evaporator wall are performed under 40% load through large quantities of temperature metrical points.

通过安装大量的温度测点对锅炉40%负荷运行时的水冷壁温度进行了比较全面的测试。

In production, the main difficulty is the manufacture of the evaporator spiral wall especially it's transition section.

此锅炉制造中最大的难点在于螺旋水冷壁，特别是其中过渡段的制造。
