摘要:
针对生物质中氯含量较高,生物质直燃锅炉在运行中经常发生氯引起的过热器高温腐蚀问题,模拟生物质直燃锅炉过热器工作的温度条件和含HCl的烟气气氛,利用管式炉采用增重法对15CrMoG,12Cr1MoVG,12Cr2MoWVTiB,20G,T91,TP347H和0Cr25Ni20七种常用的过热器管材进行高温腐蚀实验.研究各管材的腐蚀增重拟合曲线,并基于热分析动力学方法对高温腐蚀的动力学模型进行分析.结果表明,腐蚀增重符合抛物线规律,温度和HCl浓度对腐蚀速度影响显著.7种管材中,T91,TP347H,0Cr25Ni20具有较好的耐高温腐蚀性能,这可能与它们的合金组分中较高的镍含量有关.动力学分析结果显示,高温腐蚀反应遵循一维扩散动力学模型.
Abstract:
Aiming at the problems that biomass-fired boiler often experiences chlorine-induced high-temperature corrosion of superheater due to high amount of chlorine in biomass, high-temperature corrosion experiments are conducted on seven types of commercial superheater alloys, i.e. 15CrMoG, 12Cr1MoVG, 12Cr2MoWVTiB, 20G, T91, TP347H and 0Cr25Ni20 using a weight-increase method in a horizontal-tube furnace, with temperature conditions and HCl-containing atmosphere simulating the working conditions of superheater in a biomass-fired boiler. Mass gain curves of the specimens are plotted and corrosion kinetics are studied using thermal analysis kinetics method. The experimental results show that the mass gains fit with parabolic curves and corrosion rates are strongly influenced by temperatures and HCl concentrations. Among the tested alloys, T91, TP347H and 0Cr25Ni20 have better performances against the high-temperature corrosion than the other alloys, which are attributed to their higher Ni content. The kinetics analysis shows that the high-temperature corrosion follows the one-dimensional diffusion model.
