| 摘 要： | 给出通用型系统热经济性方程,并针对国产300MW机组,分析了过热器、再热器不同喷水位置对其热经济性的影响。结果表明,无论是过热器还是再热器,其减温水从最高加热器出口分流的影响较小,而再热器喷水对机组经济性的影响远大于过热器。

| Abstract: | Gives the universal thermo economic equation,analysised the influences on the thermo economics of the unit caused by different spray positions of superheater and reheater based on domestic 300MW unit.The result shows that,attemperating water discharged from the highest heater of superheater and reheater has the least influence.And the water from reheater has a larger effect on thermo economics of the unit than the water from superheater. |
