浅析余热锅炉循环水加药处理

转炉烟道冷却壁经常开裂 ,据分析 ,开裂的主要原因为 :水质、水处理系统及其运行过程中在锅炉系统的内部产生点蚀及局部结垢后 ,部位具有较高的热阻 ,锅炉管外壁温度不均匀 ;同时 ,冷却壁急冷急热现象频繁 ,容易在冷却壁的最薄弱处产生裂纹。处理方式为在锅炉系统中增设加药计量泵 ,连续定量加入除氧缓蚀剂及阻垢剂 ,避免锅炉管内结垢及产生点蚀 ,进而避免了锅炉管外壁温度不均匀现象的产生 ,从根本上解决了烟道冷却壁经常开裂的问题

Elementary View on Waste Heat Boiler Loop Water

Cooling wall of converter flue often split, based on analyzing, the main reasons of splitting are as follows: water quality, water processing system and after the spot corrosion and part incrustation are emerged in converter system during operating, the heat resistance of this part is very high, the temperature of outer wall of converter pipe is unevenness; meanwhile, the phenomenon of quick heating and cooling for cooling wall is happen frequently, it is easy to crackle at the weakest point of cooling wall. The solution for this problem is to installating a measuring pump in converter system and add quantitative de-oxide corrosion inhibition and anti-incrustation corrosion inhibition to avoid incrustation and spot corrosion, furthermore, the phenomenon of temperature unevenness will be avoided for outer wall of converter pipe, it solved the problem of splitting for the cooling wall of flue entirely.
