Thermodynamic unit matrix analysis method for the thermal economics of coal fired power plant shaft gland system

In this paper, thermodynamic unit matrix analysis method is used to research the general regulation and thermodynamic essence of the thermo-economic changes caused by the shaft gland system. On the base of the traditional thermal balance method, we developed a new approach for calculating the shaft gland system´s thermo-economics. The new method has characteristics of clear concept, broad application and easy popularization. Furthermore, it is even more helpful to computerize the thermo-economic analysis of the thermal system and energy conservation on-line monitoring.
