工业上大量使用天然水,自来水,软化水以及脱盐水作为锅炉给水、设备冷却水或油田注水。由于水中溶解氧的存在,它对锅炉及其相关设备的腐蚀问题比较突出。由于溶氧腐蚀是一个缓慢而持续性的过程,有些企业对工业水除氧不重视,加之目前市面上已有的除氧技术普遍陈旧,致使我国50%的工业用水设备未配置除氧器,导致锅炉及采油工业设备平均寿命缩短三分之一,造成巨大的经济损失。1目前工业锅炉除氧现状1.1存在问题目前我国工业用蒸汽锅炉给水除氧大部分采用传统的热力除氧技术,不仅自耗蒸汽至少20%,降低锅炉出力,而且经热力除氧后,脱氧水水温为105℃,这样的高温水进入锅炉省煤器回收烟气余热不完全,烟囱排烟温度在250℃~300℃左右。如果能把锅炉排烟
Industrial extensive use of natural water, tap water, demineralized water and desalinated water as boiler feed water, equipment cooling water or oil field water. Due to the presence of dissolved oxygen in the water, it is more prominent on the corrosion of boilers and related equipment. As the corrosion of dissolved oxygen is a slow and persistent process, some enterprises do not attach importance to the deaeration of industrial water. In addition, the existing deaeration technology on the market is generally obsolete, resulting in 50% of industrial water equipment in our country being not equipped with deaerator, As a result, the average life expectancy of boilers and oil recovery equipment has been reduced by one third, resulting in enormous economic losses. At present, most of the deoxygenation of industrial steam boiler feed water using traditional thermal deoxidation technology, not only consume at least 20% steam, reduce boiler output, and after thermal deoxidation, deoxygenated water Water temperature 105 ℃, such high-temperature water into the boiler economizer to recover flue gas waste heat is not complete, chimney flue gas temperature of about 250 ℃ ~ 300 ℃.
