摘要
针对汽轮机冷端参数对电厂热力系统热效率和运行经济性的影响进行了研究,结合电厂工程实际,介绍2台1 000MW超超临界汽轮机冷端优化设计,从原理上分析了降低凝汽器压力、降低温差和端差的途径,以实例说明了凝汽器压力优化和循环水泵配置的优化设计过程及收效。
A study has been carried out to analyze the effects of steam turbine cold-end parameters on the thermal efficiency and operation economy of the power plant＇s thermodynamic system. Combined with the practical project, the cold-end design optimization for 2 1 000 MW ultra supercritical steam turbines has been described. The ways of reducing condenser pressure, temperature difference and terminal difference have been analyzed based on relevant principles. The design optimization and resulting effects for the condenser pressure and circulating water pump＇s configuration have been introduced with examples.
