水套加热炉的烟气腐蚀及防护

The Corrosion and Protection of the Stack Gas of the Water Jacket Heating. Boiler

本文对一台水套加热炉烟气系统的腐蚀情况进行了现场调查,分析了导致水套加热炉的烟气腐蚀的原因,阐述了腐蚀机理,纠正了四川天然气田生产中设计水套加热炉只考虑硫化氢腐蚀,忽略烟气中二氧化碳腐蚀的论点。在使用和制造方面提出相应的建议方案。

The paper proceeded on locale investigation on the corrosion circumstance of the stack gas system of a water jacket heating boiler, analyzes the reason of that the stace gas has brought on the corrosion of the water jacket heating boiler, expatiates on the corrosion mechanism, rectifies the contention that it is only the H2S corrosion that is cogitated in the designing of water jacket heating boiler in the Sichuan Natural Gas Field, neglecting the CO2 corrosion.The paper is to table a proposal on the usage and manufacture of the water jacket heating boiler to reduce the corrosion.
