On the basis of exergy loss distribution matrix equation of regenerative system and steam-water distribution matrix equation

all based on the entropy analysis method

combing with the regenerative system of one N300 steam turbine unit

and through strict mathematic deduction and induction

a general-purpose calculation model for influence of heater's terminal temperature difference upon the exergy loss distribution in regenrative system has been obtained.By using said model

the variation of exergy loss distribution in regenrative system can be accurately and rapidly calculated only through the deviation value between the outlet water data and teh drain data of upper-level heater

boasting good suitability and versatility

at the same time

it is convenient for on-line quantitatively analysing the influence of terminal temperature difference variation upon the exergy loss distribution in the regenerative system.
