一、序言 本锅炉为 AG-25/3.82-Q 型燃富氢气锅炉, 锅炉安装应按《蒸汽锅炉 安全技术监察规程》和 DL/T5047 《电力建设施工及验收技术规范》（锅炉机 组篇）的有关法律法规，并遵守本说明书的规定。本说明可作为安装单位编制安 装工艺文件和使用单位编制运行使用规程的基础资料。 二、安装说明 （一）、安装前的准备工作 1、用户收到订贷后，要按制造厂的交贷清单，清点和检查零部件及设备 是否齐全和完好，运输中有没有损坏及变形，对损坏及变形的零部件要 进行修理和校正。 2、载重车辆，起吊设备如捆扎所需要的钢丝绳、卷扬机等需要有足够的 载重能力。 （二）、建议安装顺序 1、基础验收； 2、钢架就位，找正装好，并适当拉以横梁； 3、将锅筒支座就位，并安装锅筒； 4 、安装水冷壁； 5、安装过热器； 6、安装省煤器及空气预热器； 7 、连接下降管及汽水引出管； 21-3 80B-SM2 8、安装燃烧器及其管道系统 9、将钢架、平台扶梯全部就位； 10、安装管路阀门及各种仪表； 11、水压试验； 12、砌筑炉墙，同时将检查门、看火门、防爆门、测量套管等安装并砌 入炉墙； 13、砌筑和浇注炉顶； 14、安装外护板及框架护板； 15、安装上锅筒内部装置； 16、锅筒及管道等的保温； 17、安装锅炉辅机设备； 18、锅炉辅助设备试运行； 19、烘炉、煮炉及气密性试验。 （三）、安装说明 1、基础验收 对混凝土应根据土建设计要求做，基础上予埋件不仅要按图纸核对其 装设尺寸，并应检查是不是有松动、高低不平等现象，在此基础上要根据图纸 要求划线）、钢架立柱、底板位置及纵横中心线）、锅炉纵横向中心线； 上述各种线与图纸所示尺寸的误差不应超过±1mm。 21-4 80B-SM2 2、钢架及平台扶梯的安装 ⑴、安装前应对各部件进行全方位检查是否在运输中发生变形，如有变形需校 正后方可安装。 ⑵、钢架中的立柱予埋在基础内，进行二次浇注。钢柱可以在地面组装 后成片安装，立柱间的中心距偏差小于 5 毫米，立柱顶端不垂直度偏差 小于 5 毫米，横梁标高偏差小于 5 毫米。 ⑶、钢架组装定位后，经检查合格，再进行焊接。 ⑷、在平台扶梯托架等构件上，应注意尽量不切割孔洞，必须切割时， 在切割后应予加固。 3、受压元件的安装 ⑴、检查锅筒集箱及管子外观是否因运输而损伤的痕迹，锅筒和集箱上 的管接头、法兰、管孔有无损伤。 ⑵、吊装锅筒及集箱以钢丝绳绑扎时，禁止穿在管孔或绕在短管上，外 壁应垫以木板或布，以防损坏表面。 ⑶、清除锅筒、集箱等管孔内油漆和杂物，清除焊接法兰及管端上的铁 锈。 ⑷、锅筒安装公差： a、锅筒纵向水平度±1 毫米 b 、锅筒横向水平误差±1 毫米 c 、锅筒中心线 毫米 ⑸、在整体水压试验合格后再安装锅筒内部装置，安装要符合图纸要求， 21-5 80B-SM2 连接处密封垫片要完好，密封挡板及预埋件不要有漏焊之处，以免影响蒸汽 品质。 ⑹、锅筒支座的安装应根据锅筒支座图纸做，滑动支座内的零件在组 装前应经检查和清洗，组装时不应遗漏，并应正确定位，以保证锅筒的膨胀。 ⑺、集箱安装误差： a、集箱纵向水平度±1 毫米 b 、集箱标高偏差±2 毫米 c 、上下集箱间距偏差±2 毫米 ⑻、管子安装事宜： a、受热面管子的焊接应按JB/T1613—93 《锅炉受压元件焊接技术 条件》和 JB/T1614—93 《锅炉受压元件焊接接头机械性能检测验证的方法》的有 关规定执行。 b 、过热器蛇形管、省煤器蛇形管在安装前需做通球试验，试验按 JB/T1611—93 《锅炉管子制造技术条件》执行。 c 、管排安装的排列应整齐，不应影响砌筑。 4、管路阀门仪表的安装 ⑴、管路的安装按锅炉房设计进行，管子的弯曲半径应不小于 4 倍的管 子直径。 ⑵、阀门应装在便于操作的位置，安全阀在水压试验完成后再来安装。 ⑶、安全阀的调整按劳动人事部颁发的《蒸汽锅炉安全技术监察规程》 进行。 ⑷、压力表弯管不得保温。 21-6 80B-SM2 ⑸、水位表应装排水管，并接到安全地点，以免冲洗水位表时汽水伤人。 ⑹、所有的排污管均应接到安全地点，以免伤人。 5、水压试验 ⑴、锅炉本体（包括锅筒、水冷系统、过热器、省煤器）及管路阀门和 仪表安装好后，检查及清理锅炉内部，关闭人孔、手孔，着手进行水压试 验。 ⑵、水压试验压力为锅筒工作所承受的压力的 1.25 倍。 ⑶、水压试验时，周围环境和温度不能低于 5 ℃，水温应略高于环境的气 温，但不得高于 60℃。 ⑷、锅炉上水时应将最高点的空气阀打开，将水全部注满后，再关闭空 气阀，如无漏水即可升压。 ⑸、升压速度不可太快，并且要均匀上升，每分钟升压不可超过 1.5 公 2 斤/厘米 。 2 ⑹、压力升到 3~4 公斤/厘米 时应暂停升压，检查锅炉有否渗漏和异常， 升压到试验压力后要保持 5 分钟，此时不可进行敲击检查，降压到工作所承受的压力 后关闭进水阀，做全面检查，如各焊口、法兰、阀门、人孔和手孔均无渗漏， 便认为水压试验合格。 ⑺、试验合格后便可以放水、降压，放水时要将空气阀打开。 6、炉墙砌筑 ⑴、炉墙砌筑要在水压试验合格后进行，要严格按照图纸要求做施工。 ⑵、水平烟道及尾部炉墙砌筑要严格按有关规程进行实施工程，保温砖的砌 21-7 80B-SM2 筑应平整，灰缝均匀，在砌筑不方便的部位，不能用碎
