| 摘 要： | 以热力学基础理论为依据,推导出过热水蒸气热力参数的数学模型,该模型包括水蒸气的比焓、比容、定压比热以及比熵公式.在1985年国际水蒸气骨架表允差范围内,对于水蒸气比焓公式,其压力适用范围为0～90 MPa;对于水蒸气比容公式,其压力适用范围为0～40 MPa,而模型中使用的温度范围均为273.15～1 073.15 K.该模型适用于超临界火电机组实时仿真,便于工程实用.

| Abstract: | Based on the general thermodynamic theory,a mathematical model for thermodynamic parameters of hot-shot steam is derived,it includes the formula of specific enthalpy,specific volume,specific heat at constant pressure and specific entropy.The specific enthalpy formula of steam with a pressure range from 0 MPa to 90 MPa and the specific volume formula of steam with a pressure range from 0 MPa to 40 MPa within permission error of the International Steam Skeleton Tables in 1985,and that all the model with a temperature range from 273.15 K to 1 073.15 K.The model is applied to real-time simulation for supercritical fossil power unit and convenience in application of engineering. |
