摘要
分析了空冷凝汽式汽轮机组的发展将面对低压端的设计与运行,以及机组热效率低、增加排放两大问题,提出空冷长叶片及结构强度设计的关键,以及为提高热效率应采用的一系列先进技术。这些技术对策的实施将使空冷电厂同时达到节水和节约能源消耗的目标。
Two primary issues are analyzed associated with design and operation of low pressure turbine. lower thermal efficiency and high environmental pollution in view of development of air cooling condensing turbine units. The key aspects of the mechanical design for long blade and a series of the advanced technology on design and thermal cycle are presented to increase the thermal efficiency and improve emission, which can be used to reach the target of both energy and water saving.
