水垢可以缩短蒸汽发生器运用寿数
Scale can shorten steam generator to use the number of days
一般蒸汽发生器运用寿数,在正常运用条件下,能够接连运转20年摆布。但为什么如今大部分运用单位的锅炉没有到达这一寿数呢?其缘由是多方面的,其中之一就有水垢的影响。
The general boiler USES the number of days, under normal operation conditions, can run for 20 years. But why do most of today's boilers not get to this longevity? The causes are manifold, and one of them has the effect of scaling.
锅筒发作鼓疱,挖补修正后,应该对其恰当降压运用,以确保安全。这么一来,关于请求蒸汽压力较高的单位来说,就不得不更换新的锅炉。有些单位也会因蒸汽压力过低而影响产品质量,乃至呈现次品,直接影响经济效益。
When the drum is in a blister, it should be applied properly to ensure safety. In this way, new boilers will have to be replaced for units that request high steam pressure. Some units will also affect the quality of the products due to the low pressure of the steam, and even the defective products, which directly affect the economic benefits.
有些蒸汽发生器因鼓疱面积过大且变形严峻而不得不作报废处理;有的锅炉虽然能够修正,但因修补费用过高,无价值,也不得不报废。
Some boilers have to be scrapped due to their large size and severe deformation. Some boilers can be corrected, but they are too expensive to repair and have to be scrapped.
当酸洗办法不当或酸洗频频也会影响锅炉的运用寿数。别的,因为水垢中富含卤素的离子,在高温下对铁有腐蚀作用,会使金属内壁变脆,并不断地向金属壁的深处开展,构成金属的腐蚀,缩短蒸汽发生器运用寿数。

Improper acid cleaning or acid washing will also affect the use of the boiler. Other, because contain halogen ion in scale, corrosion of iron at high temperatures, can make the metal lining brittle, and constantly to the depths of the metal wall, constitute the corrosion of the metal, shorten the boiler using life spans.
