超临界和超超临界发电技术简介工程热力学定义水的临界状态点压力为22.115兆帕、温度为374.15℃,当达到临界点状态参数时,不再存在汽、水二相区,水直接从液态变成气态。如果水蒸气参数大于临界状态点参数,则称为超临界,相反则称为亚临界。蒸汽的高参数意味着发电效率的提高。超 Supercritical and ultra-supercritical power generation technology Brief introduction Engineering thermodynamics Define the critical state of water The point pressure is 22.115 MPa, the temperature is 374.15 ℃, when the critical point state parameters, no longer exist vapor and water two-phase zone, water directly from the liquid Become gaseous. If the water vapor parameter is greater than the critical point parameters, it is called supercritical, otherwise it is called subcritical. The high steam parameters mean increased power generation efficiency. ultra
