摘要
以国际水和水蒸气性质协会(International Association for the Properties of Water and Steam,IAPWS)1997年提出的工业用水和水蒸气热力性质模型(IAPWS-IF97)为基础,结合热平衡方程式,计算出汽轮机在不同负荷时不同循环水进水温度下所需的循环水泵运行台数,从而在不同工况点下取得循环水流量与凝汽器真空压力之间的最佳平衡点,并以此来获取最大的经济效益。
On the basis of industrial water and thermodynamic property of vapor model presented in !997 by International As- sociation for the Properties of Water and Steam, this paper discusses calculation for operation numbers of circulating water pumps under different circulating water inlet temperature with different load of the steam turbine in order to get the best balanced point of circulating water flow and vacuum pressure of the condenser under different working conditions and ac- quire maximum economic benefit.
