摘要
以汽轮机功率方程为基础,根据汽轮机变工况原理和其参数之间的变化关系,对末级进行分析计算,推导出功率增量的计算公式,确定凝汽器真空修正曲线。结果表明,考虑到热力系统变工况的影响,需要对机组功率进行修正,提高计算的实用性和精确度,扩大计算的适用范围。
This paper presents the analysis and calculation for last stage based on the turbine power equation and the relation between the power and parameters under variable conditions, deducts equation of power variation and determines correction curve of condenser vacuum, which reveals that the practicability, accuracy and applicability of the calculation are further improved by considering the effect of variable conditions on thermodynamic system and correcting the unit output.
