燃煤蒸汽锅炉腐蚀磨损有关的因素

发布日期:2019-09-18 13:00:43 访问次数:345

小易为你介绍一下燃煤蒸汽锅炉腐蚀磨损有关的因素有哪些?

经过长时间的工作,锅炉的内部部件会受到一定的侵蚀和磨损。 哪些因素与导致的电线磨损有关? 在计算燃气蒸汽锅炉腐蚀时的钢丝磨损量时应考虑哪些因素?
 
 考虑到摩擦载荷面积系数,应考虑锅炉腐蚀磨损的钢丝磨损量,其尺寸随迎角和磨削量的变化而变化。 为了比较在不同攻角下测量的导线磨损量,换算成相同面积的导线磨损量是实际测量的导线磨损量。 
 注意,当迎角恰好等于90°时,它是表面疲劳磨损并且与灰分的性质更好地相关。 对于锅炉碳钢,当受到石英磨料的腐蚀磨损时,这种磨损过程不能以单一模式处理,这是多种磨损形式的结合。
 

 可以看出,为了减少卧式燃煤蒸汽锅炉的腐蚀和磨损,有必要从许多方面入手,不仅要调整适当的迎角,还要使用抗腐蚀材料。 锅炉,以防止其表面损坏。 延长其使用寿命,同时确保正常使用。

Xiaoyi will introduce to you some factors related to corrosion and wear of coal-fired steam boilers。


After a long period of work, the internal parts of the boiler will suffer certain erosion and wear. Which factors are related to wire wear? What factors should be considered in calculating steel wire wear during corrosion of gas steam boilers?



Considering the area coefficient of friction load, the wear of steel wire in boiler corrosion wear should be considered. Its size varies with the change of angle of attack and grinding quantity. In order to compare the wear of conductors measured at different angles of attack, the wear of conductors converted into the same area is the actual wear of conductors measured.


Note that when the angle of attack is exactly equal to 90 degrees, it is surface fatigue wear and is better related to the properties of ash. For boiler carbon steel, when it is corroded and worn by quartz abrasive, the wear process can not be treated in a single mode, which is a combination of various wear forms.



It can be seen that in order to reduce the corrosion and wear of horizontal coal-fired steam boilers, it is necessary to start from many aspects, not only to adjust the appropriate angle of attack, but also to use anti-corrosion materials. Boiler to prevent surface damage. Extend its service life, while ensuring normal use.
