摘要 湿化器是湿空气透平(HAT)循环的关键部件,其性能优劣对于循环的性能有着重要的影响。对采用新型SiC泡沫陶瓷填料的湿化器在加压条件下的湿化性能进行了实验研究,分析了水气比、进口水温、操作压力以及进口空气温度对湿化过程的影响,研究表明,提高水气比或进口水温会使进出口空气温差、含湿量差相应增加,湿化器节点温差增大。操作压力升高,进出口空气温差增加,含湿量差减小。进口空气温度增加会使得出口水温升高,但对出口空气的温度及含湿量影响不大。 A humidifier constitutes a key component in a humid air turbine cycle and its performance has an important influence over the cycle performance.The humidifying performance of a humidifier under a pressurization condition using a new-type SiC foam ceramic packing was experimentally studied and the influence of the water/air ratio,inlet water temperature,operating pressure and inlet air temperature on the humidifying process,analyzed.The research results show that to increase the water/air ratio or inlet water temperature can increase accordingly the inlet and outlet air temperature difference and moisture content difference as well as the node temperature difference of the humidifier.To increase the operating pressure can increase the inlet and outlet air temperature difference and decrease the moisture content difference.To increase the air temperature can increase the outlet water temperature but exercise no big influence on the outlet air temperature and moisture content.
