导言1969年3月美国电力公司向拔柏葛公司订了一台130万瓩锅炉。该机组安装在西弗吉尼亚州的阿莫斯(Amos)电站(3号机组),要求于1973年投入运行。1970年该电力公司又订购了三台130万瓩机组,其中两台安装在俄亥俄州的加温(Gavin)电站,第四台的安装地点尚未确定。锅炉的额定蒸发量为4443吨/时,蒸汽参数为543/538℃和270公斤/厘米~2(表计),再热器蒸汽量为3616吨/时。使用单位决定:第一,锅炉和辅机均为室内布置,以免仪表线路可能发生冻结,这个问题历来就是露天布置锅炉的一个严重的问题。经常导致强迫停炉,而室内布置为检修人员以后在机组运行时维
Introduction In March 1969, the U.S. utility company ordered a 1.2 million boilers to beco. The unit was installed at Amos Power Station in West Virginia (Unit 3) and was commissioned in 1973. In 1970, the utility company ordered three 1.3-megawatt units, of which two were installed at Gavin Power Station in Ohio and the fourth was not installed at the site. The rated boiler evaporation is 4443 tons / hour, the steam parameters are 543/538 ° C and 270 kg / cm 2 (meter), and the reheater steam volume is 3616 tons / hour. The use of units to determine: First, the boiler and auxiliary equipment are indoor layout, so instrumentation lines may freeze, this issue has always been a serious problem open-air layout of the boiler. Often lead to forced shutdown, and indoor layout for the maintenance staff after the operation of the unit dimension
