1·The problem of boilers main steam temperate to be rather high in super critical pressure concurrent boiler at start-up initial stage, which should be paid enough attention to was discussed.

讨论了超临界压力直流锅炉在启动初期应充分注意锅炉主汽温度偏高的问题。

2·Calculation and comparisons show that the error caused by the assumption of concurrent temperatures of working medium and heated surfaces in boiler dynamic models is not negligible.

通过计算和比较表明，在锅炉动态模型中假定工质温度与金属温度同步变化所引起的误差往往是不容忽视的。
