  燃气热风炉点火操作不当会引起爆炸。那么燃气热风炉应该如何操作呢?
  Improper ignition operation of gas hot blast stove will cause explosion. So how should the gas stove be operated?
  点火前:
  Before ignition:
  1. 检查电控柜是否处于待机状态;
  1. Check whether the electronic control cabinet is in standby state;
  2. 检查供气压力是否符合要求,阀门和管道是否有泄漏,阀门关闭是否可靠,有任何问题必须及时排除;
  2. Check whether the supply pressure meets the requirements, whether the valves and pipes are leaking, whether the valves are reliable to close, and any problems must be eliminated in time;
  3.检查燃烧风机、烟气诱导风机、电机的转向是否正确,阻尼器是否灵活可靠,并将阻尼器调整到“关”位置
  3. Check whether the direction of combustion fan, flue gas induced fan and motor is correct, whether the damper is flexible and reliable, and adjust the damper to the "off" position.
  4. 检查压力防爆孔是否打开灵活。
  4. Check whether the pressure explosion-proof hole is flexible to open.

  当点火:
  When ignition:
  1. 启动风机,开启风机5-10分钟,清除炉内残留气体,避免爆炸。记得这一步。
  1. Start the fan, open the fan for 5-10 minutes, remove the residual gas in the furnace, avoid explosion. Remember this step.
  2. 排气完毕后,关闭燃烧风机,减小抽风机门的开度或关闭抽风机,将炉膛内水柱调至5~20mm的微负压。
  2. After exhaust, close the combustion fan, reduce the opening of the exhaust fan door or close the exhaust fan, and adjust the water column in the furnace to 5-20 mm of micro-negative pressure.
  3、点火棒着火。首先打开常开阀,打开点火杆上的阀门,然后点火。调整点火杆上阀门的开度,使火焰稳定。稳定后,从点火孔插入,让它燃烧。
  3. The ignition rod is on fire. First, open the normal opening valve, open the valve on the ignition rod, and then ignite. Adjust the opening of the valve on the ignition rod to stabilize the flame. After stabilization, insert it from the ignition hole and let it burn.

  4、炉点火。
  4. Furnace ignition.
  5. 关闭点火杆,首先关闭常开阀1,然后关闭点火杆上的调节阀。
  5. Close the ignition rod, first close the normal open valve 1, and then close the regulating valve on the ignition rod.
  6. 加大引风机的开启度或打开引风机,调整风门。
  6. Increase the opening degree of the induced draft fan or open the induced draft fan and adjust the air door.
  7、当炉膛点火未点火或熄火时,应重复上述步骤1~6。
  7. When the furnace ignition is not ignited or quenched, the above steps 1-6 should be repeated.
  8. 炉子加热后,打开鼓风机加热。加热时,先逐渐增大风量,观察火焰是否呈蓝色,并适当调整风机扇门的开启度,使火焰呈蓝色,然后调整风机扇门的开启度,并保持炉内为微负压5~20mm水柱。
  8. After the furnace is heated, turn on the blower for heating. When heating, first increase the air volume gradually, observe whether the flame is blue, and adjust the opening degree of fan door appropriately to make the flame blue, then adjust the opening degree of fan door, and keep the water column of 5-20 mm of micro-negative pressure in the furnace.
  9、加热时,应控制天然气阀门、燃烧风机和感应风机风门的开启,使炉膛温度逐渐升高,避免炉体部件由于热不平衡而产生过多的热应力而影响使用寿命。
  9. When heating, the opening of natural gas valves, combustion fans and induction fans should be controlled so as to gradually increase the furnace temperature and avoid excessive thermal stress of furnace components due to thermal imbalance affecting service life.
  加热过程中观察燃烧火焰,保持火焰蓝色,控制炉内温度和流量,调节鼓风机风量,将炉内热风出口保持在200~250℃。
  During the heating process, observe the combustion flame, keep the flame blue, control the temperature and flow rate in the furnace, adjust the air flow rate of the blower, and keep the hot air outlet in the furnace at 200 ~ 250 C.
