高温受压锅炉外部检验工作高温受压锅炉外部检验工作.doc

高温受压锅炉外部检验工作 锅炉在运行过程中,受压元件在高温高压水汽介质作用下,在外部高温火焰辐射或烟气冲刷下,可能发生腐蚀、变形、磨损、结垢、过烧、泄漏等缺陷,还会出现堵灰、结渣等现象,更严重的发生爆管甚至爆炸事故,如果不及时发现并加以消除,最终将会导致设备破坏。锅炉检验工作就是将锅炉的危险降低到最低限度的一项重要的工作。 Boiler in operation process, the pressure parts under high temperature and high pressure steam medium role, under the outside high temperature flame radiation or flue gas erosion, corrosion, deformation, wear may occur, scaling, burnt, defects such as leakage, there will be blocking the phenomenon such as ash, slagging, the more serious the happening of the tube explosion accident, even if not discovered in time and try to eliminate, will eventually lead to equipment damage. Boiler inspection is to lower risk of an important work to a minimum. 　　二、锅炉检验的内容 The content of the two, boiler inspection 　　1.外部检验可以在锅炉运行过程中进行。其检验内容包括:(1)人孔、手孔、检查孔是否漏水、漏汽;(2)汽、水阀门和管道的状况;辅助设备运行情况;炉墙、钢架及炉膛燃烧情况;(3)安全附件是否齐全、灵敏;(4)锅炉的操作规程、岗位责任制、交接班等规章制度的执行情况;(5)水处理设备运行情况。 1. External inspection can be conducted in the process of boiler operation. The inspection items include: (1) manhole, hand hole, check hole leakage, leakage; (2) the steam, the condition of water valve and pipeline; Auxiliary equipment running status; Furnace wall, steel frame and combustion chamber of a stove or furnace; (3) whether safety accessories are complete, sensitive; (4) boiler operation procedures, post responsibility system, rules and regulations implementation such as succession; (5) water treatment equipment operation. 　　2.内外部检验,又叫定期停炉检验,它需要在锅炉停炉后进行。内外部检验的重点如下:(1)上次检验有缺陷的部位;(2)锅炉受压元件的内、外表面,特别是开孔、焊缝、扳边等处有无裂纹、裂口和腐蚀;(3)管壁无有磨损和腐蚀;(4)锅炉的拉撑以及与被拉元件的结合处有无裂纹、断裂和腐蚀;(5)胀口是否严密, 酿酒设备管端的受胀部分有无环形裂纹,铆缝是否严密,有无苛性脆化;(6)受压元件有无凹陷、弯曲、鼓包和过热;(7)锅筒和砖衬接触处有无腐蚀,受压元件或锅炉构架有无因砖墙或隔火墙损坏而发生过热;(8)受压元件水侧有无水垢、水渣,进水管和排污管与锅筒的接口处有无腐蚀、裂纹,排污阀和排污管连接部分是否牢靠;(9)安全附件是否灵敏、可靠,水位表、水表柱、安全阀、压力表等与锅炉本体连接的通道有无堵塞;(10)自动控制、讯号系统及议表是否灵敏可靠。 2. Internal and external inspection, also called the furnace inspection regularly, it needs to stop at boiler furnace. The focus of the internal and external in
