| 摘 要： | 值与环境温度的高低有关。我国一般在计算过程中值的选取是以固定的环境条件298.16K,0.1MP为基准,但是环境条件是随着时间与地域而变化的。通过选取不同的环境条件,对国内300MW、超临界600MW以及1 000WM机组回热系统的热力参数及其值进行了查值,并在此基础上对回热系统加热器的损进行了计算,分析了不同环境温度基准对回热系统加热器损变化的影响,为回热系统乃至整个机组分析的基准点的选择提供参考。

| Abstract: | The value of exergy is related to the ambient temperature level.The constant condition(298.16K,0.1MP)is always used to be the baseline in choosing the value of exergy during the calculation,but the environmental conditions are varied with time and geography.The author investigates the value of exergy about the domestic 300MW,600MW supercritical units and 1000WM regenerative thermal parameters of the system by selecting different environmental conditions,calculates the exergy loss of the regenerative system ... |
