燃气热风炉在使用一段时间后,司炉工就应该对工作中的燃气热水热风炉进行保养,保养是为了燃气热水热风炉更好的工作,并且能延长使用期限,豫园热风炉整理了3种保养方法,供各位参考。通过以上三种方法对热风炉进行保养,选择保养的方法要根据使用燃气热水热风炉的状态决定,不能盲目的进行,如果司炉工不能完成,就要咨询相关工作人员,帮助完成,延长热水热风炉的使用时间。

After a period of use, the fireman should maintain the gas hot-water stove in his work. Maintenance is for the better work of the gas hot-water stove and can extend the service life. Yuyuan hot-air stove has arranged three maintenance methods for your reference. Through the above three methods to maintain the hot blast stove, the choice of maintenance methods should be based on the use of gas hot blast stove status, can not be blindly carried out, if the fireman can not complete, it is necessary to consult the relevant staff to help complete, prolong the use time of hot blast stove.

一、压力保养

1. Pressure maintenance 适用于生产备用热风炉或停运进行短暂检修时间不超过一周的热风炉。

It is suitable for producing hot air stoves with a standby hot blast stove or shutdown for a period of no more than one week.

①、停炉后把炉水全部放尽,将炉内的水垢、水渣清理干净,重新加入合格软化水。

After stopping the furnace, all the furnace water is discharged, the scale and slag in the furnace are cleaned up, and qualified softening water is added again.

②、定期用小火加热,或定期利用相邻热风炉的蒸汽加热炉水,使热风炉内的炉水温度夏季应保持在环境温度+10℃左右,冬季应保证炉水不冻结,关闭所有放空阀、排污阀和放水阀,防止漏水。

(2) Heating furnace water with small fire regularly or using steam from adjacent hot stoves regularly, so that the temperature of furnace water in hot stoves should be kept at ambient temperature + 10 C in summer and not frozen in winter, closing all vent valves, drain valves and drain valves to prevent water leakage.

③、热风炉定期给水,保持热风炉内压力为0.05MPa~0.1MPa防止空气进入锅筒。

3. Regular supply of water in hot blast stove keeps the pressure in the hot stove 0.05MPa~0.1MPa to prevent air from entering the boiler.

二、湿法保养

Two. Wet maintenance

湿法保养一般适用于停炉时间不超过一个月的热风炉的保养。

Wet maintenance is generally suitable for maintenance of hot blast stove with no more than one month's shutdown time.

①、停炉后按规定时间放尽炉水,将水垢、水渣、烟灰清楚干净。

1. When the furnace is stopped, drain the scale, slag and soot clearly according to the prescribed time.

②、关闭所有的人孔、手孔、阀门等,与运行的热风炉完全隔绝。

Close all manholes, hand holes, valves and so on, and completely separate from the running hot stove.

③、用合格软化水配制碱性保护溶液,按每吨炉水加入氢氧化钠Na(OH)8kg~10kg,或加碳酸钠(NaC03)20kg,或加磷酸钠(Na2P03)20kg。

(3) Preparing alkaline protective solution with qualified softening water, adding Na OH 8 kg~10 kg per ton of furnace water, NaC03 20 kg or Na2P03 20 kg.

④、用专用泵将配制好的碱性保养溶液注入热风炉。

4. Use the special pump to inject the prepared alkaline maintenance solution into the hot blast stove.

⑤、当保护溶液全部注入后,开启给水阀将合格软化水注满热风炉,直至水从空气阀溢出为止,然后再关闭空气阀和给水阀,开启专用泵循环,使溶液混合均匀。

(5) When the protective solution is fully injected, open the water supply valve and fill the hot blast stove with qualified softening water until the water overflows from the air valve. Then close the air valve and the water supply valve and open the special pump cycle to make the solution mix evenly.

⑥、在整个保养期间,应定期用微火烘炉保持受热面外部干燥,定期开启泵循环,使各处溶液浓度一致,还要定期取溶液化验和补充药液,使溶液PH值在10~12之间,保证炉水的碱度。

During the whole maintenance period, the external drying of heating surface should be maintained by micro-fire oven regularly, the pump circulation should be opened regularly, so that the concentration of solution everywhere is the same, and the solution test and supplementary liquid should be taken regularly, so that the PH value of solution is between 10 and 12, to ensure the alkalinity of furnace water.

⑦、在冬季要采取相应的防冻措施。

In winter, corresponding measures should be taken to prevent frostbite.

三、干法保养

Three, dry maintenance

干法保养适用停炉时间较长,一般时间超过一个月,特别是夏季停用的采暖热水热风炉。

Dry maintenance is suitable for stopping the stove for a long time, usually more than a month, especially in summer stoppage of heating hot water hot blast stove.

①、停炉后,将炉水放尽,清楚炉内的水垢,水渣和受热面的烟灰。

1. After the furnace is stopped, the furnace water is exhausted, and the scale, slag and heating surface of the furnace are clear.

②、关闭热风炉的供水管、给水管、排污管上的阀门,或用隔板堵严,与其它运行热风炉完全隔绝。

(2) Close the valves on the water supply pipes, water supply pipes and sewage pipes of the hot blast stove, or close them with partitions, so as to completely isolate them from other running hot blast stoves.

③、打开人孔、手孔,使热风炉自然干燥,若热风炉潮湿,用微火将热风炉本体及炉墙,烟道烘干。

(3) Open manholes and hand holes to make the hot stove dry naturally. If the hot stove is wet, use a light fire to dry the main body, wall and flue.

④、选用适量干燥剂。常用干燥剂有无水氯化钙(CaCl2)和生石灰(CaO2),CaCl2按每立方米水容积2kg定量放置,要求选用15mm左右的颗粒;生石灰按每立方米水容积3kg定量放置,要求选用10mm~30mm的块状物。

Select suitable desiccant. Commonly used desiccants are anhydrous calcium chloride (CaCl2) and quicklime (CaO 2). CaCl2 is placed quantitatively at 2 kg per cubic meter of water volume, requiring the selection of particles of about 15 mm; quicklime is placed quantitatively at 3 kg per cubic meter of water volume, requiring the selection of blocks of 10 mm to 30 mm.

⑤、热风炉干燥后,将装有干燥剂的托盘放入炉膛和锅筒中,以吸收潮气,要求干燥剂不能与热风炉受热面直接接触。

(5) After drying, the tray with desiccant is put into the hearth and pot drum to absorb moisture. It is required that the desiccant should not contact directly with the heating surface of the hot blast stove.

⑥、干燥剂放入热风炉一个月内应每周定期检查一次,看受热面有无腐蚀,及时更换失效的干燥剂,一个月以后每半个月检查一次。

(5) Drying agent should be checked periodically once a month in hot stove to see if the heating surface is corroded or not, change the failed drying agent in time, and check every half month after a month.
