In order to evaluate reclaiming effect of energy with auxiliarysteam or water, energy balance analysis of thermal system local variation is necessary.
为了评价辅助蒸汽或者水的热量利用效果，热力系统的局部变化分析是非常必要的。

Design considerations for the thermodynamic system, plant layout, steam turbine proper, the oil system for governing and safety control, butterfly valves and some major auxiliary equipment are given.
Therefore, the paper constructs the virtual thermal system, which is adapted to EEDM equation, and proposes the universal expression rules of each auxiliarysteam-water component.
