盘管加热炉操作规程 | 2011-2-27 10:57:00
盘管加热炉操作规程 
 
 
 一、启动前的检查
  1、检查各仪表是否正常,人孔、着火孔、防爆门是否关闭。
  2、检查烟囱挡板开关是否灵活,并将打开进行通风。
  3、检查加热炉进出口阀门以及燃气管线各阀门是否灵活、好用。
  二、启动
  1、倒通燃气阀门,燃气调压阀调压后压力为0.01MPa;
  2、启动炉区电源,给各设备送电,启动所有记录仪表及控制仪表;
  3、调整炉后工艺流程,倒通加热炉上下游流程,使加热介质流入炉管内;
  4、按燃烧器使用说明要求启动燃烧器,使其正常运行;
  5、调节燃烧器风门,使燃烧完全,并控制火焰长度,严禁火焰舔烧炉管;
  6、扩建加热炉出口温度保持在80℃左右,120万吨加热炉出口温度保持在60℃左右,排烟温度保持在150℃—200℃之间;
  三、巡检内容
  加热炉每2小时巡检一次,巡检内容为:
  1、检查炉体各部件、阀门是否有漏气、漏油、漏风等现象;
  2、观察加热炉进出口压力、温度是否在正常范围内,进炉压力是否在0.3MPa至0.5MPa之间,出炉压力是否在0.25MPa至0.4MPa之间,燃气压力是否在0.004MPa至0.008MPa之间,并作好记录;
  3、燃气流量计是否正常运行,记录累计流量;火焰长度是否正常,烟囱是否有冒黑烟现象,燃烧器运行是否正常,如检查中发现异常现象及时处理或上报并作好记录;
 四、停炉操作
  1、停炉应提前2至4小时通知加热炉岗位和上下游岗位;
  2、停炉应按先降温后停炉的顺序进行;
  3、关闭燃烧器;
  4、临时停炉时,炉管内介质应继续流动,不需关闭进出口,以防管内介质凝固;
  5、如维修或生产需要停炉,关闭加热炉上下游阀门,切断燃气阀门并排放管内介质;
  五、倒炉操作
  1、按启动前检查的要求,检查加热炉;
  2、打开加热炉上下游阀门,使介质流入加热炉盘管内,关闭要停用的加热炉燃烧器,使之停炉;
 3、打开燃气阀门,给燃烧器送气,启动燃烧器,观察燃烧情况、温度、压力等参数;
  4、等加热炉运行正常后,关闭另一台加热炉上下游阀门,并作好记录;
  六、紧急停炉
  1、加热炉上下游生产不正常,压力波动大;
  2、加热炉介质停止流动或流量过小,温度上升过快;
  3、加热炉进出口压力表、温度计失灵而无其他仪表指示;
  七、维护与保养
  1、加热炉进出口阀门、燃气管线各阀门等岗位值班人员负责一季度保养一次,并作好记录;
  2、燃烧器电机,由设备物资办公室负责每4500小时保养一次,并作好记录;
  3、燃烧器由电器仪表室负责每6个月检查或保养一次,并作好记录;
  4、每6个月检查一次耐火衬里,对有缺陷的地方应进行维修,由工程技术室负责并作好记录并存档;
  5、每年清除一次灰垢,由工程技术室负责并作好记录并存档;
  6、炉膛内如发现烧坏应及时修复,并在表面涂高温涂料一层。
