高温高压电站锅炉蒸发受热面某些部件的工作可靠性,在很大程度上取决于内部汽液两相流体的流动情况。几十年来,不少国家为此进行大量的探讨研究工作。目前,随着大量采用超高压、超高温及亚临界蒸汽参数,在实际设备上进行试验研究困难愈来愈大。在实验室内采用蒸汽-水模型试验方法也往往由于参数太高,测量精度低以及试验设备要求太高等问题而难于进行,所以探索一种简便而可靠的试验方法已成为一项十
The reliability of the operation of certain components of the evaporative heating surface of high-temperature and high-pressure utility boilers depends to a large extent on the flow of the internal vapor-liquid two-phase fluid. For decades, many countries have done a lot of research and research for this purpose. At present, with the extensive use of ultra-high pressure, ultra-high temperature and subcritical steam parameters, experimental studies on actual equipment have become more and more difficult. The use of a steam-water model test method in a laboratory is often difficult due to parameters such as too high a parameter, low measurement accuracy, and high requirements on the test equipment, so it has become one of the ten to explore a simple and reliable test method
