摘要

定热量等效热降用作局部分析时

必须把求得的做功变化

通过转换系数λ转换成新蒸汽的等效热降变化

方能求得经济指标的相对变化。结合 q γτ矩阵方程

针对进出热力系统的 3类典型辅助汽水 (从加热器的汽侧、水侧进出系统

纯热量进出系统 )

构造了相应转换系数λ的计算模型

完善了定热量等效热降的应用体系。以某台国产N12 5 135 / 5 5 0 / 5 5 0再热机组为例

讨论了模型的适用性。

Abstract

alWhen an equivalent heatreduction under constant heat quantity is used as partial analysis

it is necessary to change workdone obtained into equivalent heareduction variation of the live steam through conversion factor λ

and then the relative variation of economic index can be evaluated. Combining with qγτ matrix equation

the calculation models of conversion factor corresponding to three kinds of auxiliary steamwater entering into and outgoing from the thermal system （i、e. from steam side or water side of the heaters

or with pure heat quantity） have been established

perfecting the application system of equivalent heatredution under constant quantity. Taking a homemade N 125135/550/550 unit as example

the adaptability of the models has been discussed.
