The exergy transfer analysis model for utility boilers has been estabished.In the light of Exergy Evaluation Criterion In Engineering

the evaluation principle for exergy transfer

exergy flux density

and exergy resistance etc.has been put forward

and the exergy transfer coefficient being defined

the exergy transfer analysis for boilers of 100 MW unit being completed.Through comparision with the conventional heat transfer and excergy analysis

it is believed that the exergy transfer analysis can provide new information about technical evaluation

thereby

the energy transfer can have a more complete and comprehensive dynamic analysis.
