中文摘要 | 模拟生物质锅炉过热器区的气相条件以及过热器管壁沾灰状况,在500~600℃范围内对奥氏体不锈钢TP347H进行了腐蚀试验研究。通过测定试样的增重量,得出了腐蚀动力学曲线;利用配有能谱分析仪的扫描电镜和X射线衍射仪,对试样腐蚀后的形貌结构、元素含量和腐蚀产物的组成成分进行了分析。结果表明,当试片表面存在生物质灰时,TP347H的腐蚀速率比无灰大大增加;沾有生物质灰的TP347H对反应温度非常敏感,随着反应温度的增加,TP347H的抗腐蚀性能逐渐降低。; A study on corrosion test of TP347H austenic stainless steel has been carried out in a temperature range of 500~600 ℃,simulating the atmosphere and ash deposition on tube-wall of superheaters in biomass-burned boilers.The corrosion dynamic curves have been obtained through mass gain;the appearance,elements content,and composition of corrosion products after corrosion of specimens being analysed by using the scanning electron microscope(SEM) equiped with energy dispersive spectrometer(EDS) and X-ray diffraction(XRD) meter.Test shows that the corrosion rate of TP347H steel with biomass ash deposition is greatly increased compared with that without biomass ash deposition;the TP347H steel with biomass ash deposition is very sensitive to the reaction temperature,the anti-corrosion performance of TP347H steel is gradually decreased with the increase of reaction temperation. |
