Wall Thinning

Abnormal wall thinning of elbows were detected in the economizer at waste heat boiler system. In the failure analysis, material analysis, metallographic examination, macro- and microstructure analysis and composition analysis were conducted. We analyzed the causes and mechanisms of abnormal wall thinning. The failure causes were found to be sulfuric dew point corrosion. Finally, corresponding countermeasures were suggested.

Industrial Waste Heat

In order to improve the utilization rate of industrial waste heat and improve the fine design level of waste heat power station, this paper constructs the mathematical model of waste heat boiler and steam turbine, and puts forward the optimization design method of thermal system of waste heat power generation project. By using typical cases, it is proved that there is the optimal design pressure of HRSG, which makes the power generation of the system maximum, and provides a method to improve the power generation of HRSG.
