汽封漏汽对机组经济性的影响

Influence of gland leakage on economy of unit

超临界汽轮发电机组设计的热耗率具有较高循环热经济性,在实际的运行中,有时热经济性方面优势并没有真正体现出来。以某一机组为例,分析了高压部分汽封漏汽对经济性的影响,定量地给出了具体影响值,对同类机组有一定的借鉴意义。

The designed heat consumption rate of supercritical steam turbine generation unit has higher circulation thermo-economy, but sometimes this advantageous was not realized in practical operation. In this paper the author took a unit as an example, analyzed the influence of gland seal leakage in high pressure parts on economy of the unit, and gave some concrete influence values quantitatively, the results can be used as a reference for the similar units.
