回热加热器的散热对机组热经济性的影响

The Effect of Heat Release of a Regenerative Heater on the Economics of a Steam-Electric Generating Set

本文用等效热降法分析回热加热器的散热对汽轮发电机组热经济性的影响，提出了有效油汽系数的概念，用有效抽汽系数来评价加热器的散热损失对机组热经济性影响的大小。

By the use of an equivalent heat drop method an analysis was performed of the effect of regenerative heater heat release on the thermodynamic economics of a turbine-electrical generating set with the conception of an effective steam extraction factor being proposed, The effective steam extraction facfor can be employed to evaluate the effect of the heater heat release loss on the thermodynamic economics of the above-cited generating set.
