摘要

印度不断增长的电力需求和排放标准要求更高效的燃煤电厂。电厂从亚临界蒸汽状态向超超临界(USC)蒸汽状态的转变可以提高12%的效率,减少35%的二氧化碳排放。有必要在实验室规模上开发和鉴定高温高压超超临界蒸汽条件下的材料。样品材料在700°C的高温空气和700°C/243 bar的高压蒸汽中暴露1000小时,在接收和晶界增强条件下。晶界增强包括对冷轧和退火样品的热机械工艺进行优化。分析了空气和蒸汽氧化对镍基候选高温合金in617的影响。在特制的PARR 4650系列高压灭菌器上进行蒸汽氧化,并在扫描电子显微镜下对氧化样品进行表征,以评估氧化鳞片。晶界工程材料的性能优于接收样品。总体而言,在空气和蒸汽条件下,in617表现更好,体重增加少得多。

Long-Exposure Air and Steam Oxidation Characteristics of IN 617 Alloys
India’s growing power demands and emission norms require more efficient coal-based power plants. The shifting of power plants from subcritical to ultra-supercritical (USC) steam conditions could improve efficiency by 12% and reduce CO2 emissions by 35%. There is a need to develop and qualify materials under ultra-supercritical steam conditions with high temperatures and high pressures in laboratory scale. The sample materials were exposed to high temperatures of 700 °C under air and high pressure steam at 700 °C/243 bars for 1000 h in as-received and grain-boundary-enhanced conditions. Grain boundary enhancement included optimization of a thermo-mechanical process involving cold rolling and annealing of samples. The effect of air and steam oxidation on IN 617, a nickel-based candidate superalloy, was analysed. Steam oxidation was performed on a custom-built PARR 4650 series autoclave, and the oxidized samples were characterised under scanning electron microscopy, to evaluate the oxide scales. The grain-boundary-engineered material performed better than the as-received samples. IN 617 overall fared better under both air and steam conditions, with far less weight gains.
