摘要
近年,350MW超临界火力发电机组技术发展迅速,在中国大陆地区已有约20多台机组投运或正在建设中。与同容量等级的亚临界火力发电机组相比,超临界火力发电机组热经济性较高,但电厂初投资高。因此,有必要对350MW超临界参数的火力发电机组的技术经济性加以分析。通过对比亚临界参数火力发电机组,比较其技术特点和投资回报。
In recent years, 350MW supercritical power units developed rapidly and about 20 units in mainland of china are in construction or commissioning test. Compared with the same rank of subcritical unit, supercritical unit involved with high economic efficiency but higher primary investment. So it is necessary to analyze the technical economy of 350MW supercritical units. The economy of supercritical and subcritical units is compared while the technology character and invest profits are also discussed in this paper.
