Examples
- Analysis and deal with gear ' s point corrosion of 4 m winder gearbox
绞车减速器齿轮点蚀问题的分析和处理 - Tooth surface knocked burr or point corrosion on tooth surface or not in tangency
轮面磕碰，有毛刺或面发生点蚀或接触不良 - Acid dew point corrosion
酸露点腐蚀 - The results are follows : chemical composition , tensile strength , yield strength and elongation accord with standard , part corrosion of outside is dew point corrosion , equable corrosion of inside is brought by deoxidized water
结果表明：其化学成份、抗拉强度、屈服强度、延伸率均符合标准要求，管材外表面局部腐蚀是因露点腐蚀造成，管材内表面受除氧水的作用均匀腐蚀。 - Abstract : the causes for low efficiency of the heater in no . 2 crude unit of jpc refinery are described and analyzed including water leaking of steam soot blower , dew point corrosion caused by steam , soot deposits in convection chamber owning to poor soot blowing , high flue gas temperature , no heat recovery of flue gas , and poor performance of insulation lining , etc . by using sonic soot removing system , flue gas recovery system , spray coating of fiber and rock wool , as well as adjustment of flow scheme accordingly in the technical revamping . the dew point corrosion is completely eliminated , the insulation performance is improved , the heat loss is reduced by 1 . 25 % , the flue gas temperature is reduced to about 170 , and the heater efficiency is increased from 83 % to more than 90 %
文摘:分析了金陵石油化工公司炼油厂二套常减压装置加热炉存在的因蒸汽吹灰器漏水,蒸汽引起露点腐蚀及吹灰效果差造成对流室积灰，排烟温度高，烟气热量未回收利用以及炉子保温衬里效果差等问题，提出采用声波除灰系统、烟气回收系统、纤维喷涂和岩棉喷涂及相应的流程调整等改造措施.测定结果表明，本次技术改造解决了因蒸汽吹灰器漏水所造成的露点腐蚀问题，提高了保温效果，减少散热损失1 . 25 % ,排烟温度降至170左右，装置的炉效率由83 %左右提高到90 %以上
