在火电机组安装后期,要对锅炉本体进行水压超压试验。在水压试验前,须用堵板封堵主蒸汽出口联箱。对于国产机组,通常采用与主汽联箱材质相同的钢板作为堵板,比较容易。在华能丹东及大连电厂新建、扩建的2×350MW机组中,4台锅炉同为英国巴布科克—威尔科克斯公司生产的亚临界一次中间再热、单炉膛平衡通风、自然循环燃煤锅炉,其最大连续出力为1165t/h。4台锅炉的编号分别为:大连3号、4号,丹东1号、2号。锅炉本体水压超压试验压力按外方要求为汽包工作压力的1.5倍,即
In the latter part of the installation of thermal power units, the boiler should be subjected to water pressure overpressure test. Before the hydrostatic test, the main steam outlet header must be closed with a blocking plate. For domestic units, it is usually easier to use the same steel plate as the main steam header. In Huaneng Dandong and Dalian Power Plant newly built and expanded 2 × 350MW units, the four boilers with the British Babcock - Wilcox company produced subcritical a reheat, single hearth balanced ventilation, natural circulation combustion Coal boiler, the maximum continuous output of 1165t / h. Four boilers are numbered: Dalian No. 3, No. 4, Dandong No. 1, No. 2. Boiler body pressure overpressure test pressure by foreign requirements for the steam drum work pressure 1.5 times, that is
