    热风炉安装使用前需要做必要的清理

    2018-11-11 10:50:23 无锡盛发地坪科技有限公司 阅读

    新建热风炉在启动前一般都应该进行化学式热风炉清洗,以清除设备在制造、钣金加工过程中形成的高温氧化轧皮和带硅氧化皮,以及在存放、运输、安装过程中所产生的腐蚀产物、焊渣和带入的泥沙、油脂涂层、污物等.热风炉如启动前不进行化学式热风炉清洗,水、汽系统内的各种杂质和附着物在热风炉投运后会产生以下危害

    Before the start-up of a new hot blast stove, chemical hot blast stove cleaning should be carried out to remove the high temperature oxidation rolled skin and silicon oxide skin formed in the process of manufacturing and sheet metal processing, as well as corrosion products, welding slag and sediment, grease coating and dirt brought in during storage, transportation and installation. If the stove is not cleaned before start-up, various impurities and adhesives in the water and steam system will cause the following hazards after the stove is put into operation. 直接妨碍管壁的传热或者导致水垢的产生,使炉管金属过热和损坏,缩短热风炉的使用寿命。

    It directly hinders the heat transfer of the tube wall or causes scale formation, which causes the overheating and damage of the tube metal and shortens the service life of the hot blast stove.

    促使热风炉在运行中发生沉积物下腐蚀,致使炉管变薄、穿孔而引起爆管。炉水中形成碎片和沉渣,从而引起炉管堵塞或破坏正常的汽、水流动的工况。

    It causes the corrosion of the hot blast stove in the sediment during operation, which causes the furnace tube to thin and perforate and cause bursting. Fragments and sediments are formed in the furnace water, which can cause blockage or damage normal steam and water flow conditions.

    使炉水的含硅量、含铁量等水质指标长期不合格,延长了机组的启动时间,危害汽轮机的正常运行。 热风炉启动前进行热风炉清洗,不仅有利用热风炉的安全运行,还能改善热风炉启动阶段的水汽质量,使之较快达到正常标准,缩短机组启动到正常运行的时间。

    The water quality indexes such as silicon content and iron content in boiler water are not up to standard for a long time, which prolongs the start-up time of the unit and endangers the normal operation of the steam turbine. Hot blast stove cleaning before start-up not only makes use of the safe operation of hot blast stove, but also improves the water vapor quality during start-up stage of hot blast stove, so that it can reach the normal standard quickly and shorten the time from start-up to normal operation of unit.

    当机组投入运行后,固形物随补给水带入热风炉,造成某些不溶物发生沉积,不及时除去,沉积物会在炉内累积,影响热风炉的热效率,影响了热风炉安全运行,严重时会发生热风炉大面积的爆管。 如果采用完善的化学水处理或在新炉投运前,进行炉前系统的热风炉清洗,可使炉前系统的腐蚀产物减小到最小程度。高压以上机组系统中完全没有沉积也是不可能的,所以对于运行的热风炉机组也必须定期进行化学式热风炉清洗。 除垢的好处 热风炉将无垢运行,大大减少燃料消耗; 减少了热风炉清洗和维修成本;

    When the unit is put into operation, solids are brought into the hot blast stove along with the recharge water, causing some insoluble substances to deposit, which will accumulate in the furnace if not removed in time, affecting the thermal efficiency of the hot blast stove, affecting the safe operation of the hot blast stove, and large-scale tube explosion of the hot blast stove will occur in serious cases. If perfect chemical water treatment is adopted or hot blast stove cleaning is carried out before the new furnace is put into operation, the corrosion products in the front system of the furnace can be minimized. It is also impossible that no deposits exist in the system of units above high pressure, so chemical hot stove cleaning must be carried out regularly for the units running in hot stove. The advantage of scale removal is that the hot blast stove will run without scale, greatly reducing fuel consumption, and reducing the cost of cleaning and maintenance of the hot blast stove.

    避免因贺德克滤芯而产生的腐蚀、鼓包、变形、泄漏甚至爆炸等安全隐患; 大大的延长了热风炉的使用寿命; 避免因热风炉清洗或修理而停产造成的损失。

    Avoid potential safety hazards such as corrosion, bulging, deformation, leakage and even explosion caused by Hedeck filter element; greatly prolong the service life of hot stove; avoid loss caused by shutdown of hot stove cleaning or repair.
