高温硫腐蚀,high-temperature sulfur corrosion
high temperature sulfur corrosion高温硫腐蚀
1.Basing onhigh temperature sulfur corrosion mechanism,the fracture of bolts is a typical stress corrosion cracking(SCC) caused by high temperature and sulfur corrosion.根据高温硫腐蚀机理分析,确定该连接螺栓的断裂是一起典型的高温硫环境下的应力腐蚀开裂失效案例,主要是由于工作介质中含有硫化氢或者硫蒸汽所致。
2.This paper explains in detail mechanism ofhigh temperature sulfur corrosion in power plant boilers.通过阐述锅炉产生高温硫腐蚀的机理,针对实际情况,提出一些预防高温硫腐蚀的具体方法,为火力发电厂采取有效措施,降低受热面高温硫腐蚀情况提供参考。
3.Heze power plant420 t/h boiler water wall high temperature corrosion belongs tohigh temperature sulfur corrosion because of the coexistence of sulfate,iron sulfide and hydrogen sulphide corrosion.菏泽电厂420t/h煤粉锅炉水冷壁发生的高温腐蚀,为硫酸盐、硫化铁、硫化氢3种腐蚀并存,属于高温硫腐蚀类型。
3)high temperature corrosion高温硫腐蚀
1.With an eye on Huaneng Luohuang Power Plant s 360 MW sets,countermeasures againsthigh temperature corrosion are being explained,among which metal spray coatings have proved themselves to be quite effectiv高温硫腐蚀是高硫分燃煤锅炉普遍存在的问题,它会引起锅炉受热面泄漏。
4)high temperature sulphidization corrosion高温硫化腐蚀
5)high-temperature dilute sulfuric acid corrosion高温稀硫酸腐蚀
1.The leakage of 5 tubes in the same row was the result ofhigh-temperature dilute sulfuric acid corrosion initiated by the water spray of one of tubes due to the sulfuric acid dew point corrosion failure.经过对ＮＤ钢省煤器管束泄漏管子的宏观及微观分析，表明管子泄漏是首先从焊缝开始的硫酸露点腐蚀引起的；同排同位置的５根管子泄漏是由于其中一根管子发生硫酸露点腐蚀后穿孔喷水所引起的高温稀硫酸腐蚀的结果。
6)corrosion by high temperature H 2S高温硫化氢腐蚀

高温硫腐蚀分子式：CAS号：性质：即硫化。在高温含硫气氛中金属与硫反应生成金属硫化物而导致的腐蚀过程。由于金属表面形成的硫化物膜中通常含有很多缺陷，不够致密，附着性差，对基体金属的保护效果较差，所以金属的高温硫化速度一般显著高于其高温氧化速度。
